I am new with Eclipse, I have used it for SW development and in Altra environment for Nios processor. But now, I have a pretty large project that I have to manage and I would like to use Eclipse to have all the files in the system to make it easier to manage and update.
The project has multiple directories for various IPs and has multiple targets for ASCI, Xilinx and Altera FPGAs. In a near future the project will support both NIOS, Microblaze and ARM processors and I would really like to keep the whole project in one Eclipse project file if possible. I have tried several different options, but nothing seems to work properly.
I am looking for some freeware and not commercial programs like Sigasi.
Thanks in advance,
Farhad
This is an update to let others know about my progress.
Well, I finally managed to get it to work.
I installed the latest version of Eclipse on my PC
Installed version 6 of Java (the only one I could get to work)
Installed the latest version of the VEditor into Eclipse.
Mounted the Linux project directory as my P disk on PC
created a new project in Eclipse and linked it to the one on the P drive.
It took some time to figure this out, but it now works perfectly.
These are the ones I know of:
Veditor (beta) - http://sourceforge.net/projects/veditor/
sigasi free - http://www.sigasi.com/sigasi-starter-edition
signs (no longer in development) - http://sourceforge.net/projects/signs/
zamiaCAD (replacement of signs) - http://zamiacad.sourceforge.net/web/

I am a mentor for a FIRST (usfirst.org) Robotics Team Rotoraptors (http://rotoraptors.webs.com/) and we are using NetBeans (7.4) to create the program for this year’s robot (we chose Java over LabVIEW [i.e. G] and C++). We keep running into the same issue w/ NetBeans:
We install NetBeans and all requiste plug ins from FIRST
We start programming and all is well
Randomly we go to start NetBeans and it hangs on the "Starting Modules" stage.
We are not adding any other modules, updates, or other software. (The laptop we are using is dedicated to programming our robot, so it does not need anything else beyond what we are able to run before the hang up.
We always end up uninstalling then reinstalling NetBeans, after which it runs for awhile until hanging up at the same "Starting Modules" step again
After reinstalling NetBeans we are able to open the same Java project that we were working on before we saved it and turned of the laptop.
I cannot put any related events or triggers to the issue. It just happens at random.
Any and all help will be greatly appreciated by me and the kids on the team.

Next time please create a threaddump, a sampling snapshot of NetBeans (using JVisualVM from your JDK) aand attach it to a new issue at https://netbeans.org/bugzilla/
Do not forget to attach the IDE log too
Perhaps one of the plugins causes a deadlock.
Most recently I have added to NetBeans j2me plugin , then after installation of related J2ME sdk it started stick on that forever "starting modules.."
I simply uninstalled that j2me sdk outside and netbeans now starts ok again.
I use from netbeans 8.02 on windows 7 and my net beans hang constantly and recently i fixed hanging problem just with renaming "component" folder name of netbeans in following path ...AppData\Roaming\NetBeans\8.0.2\config\Windows2Local
when hanging occurred again
I'm relatively new to Android development, as well as OpenCV. I've tried out some OpenCV samples found with the sdk (using OpenCV2.4.2), as well as some here offered by Stanford University. The first two samples by Stanford worked fine (histogram equalization and color histogram). However I've spent almost a week now trying to get the remaining three to run.
I've already installed Android ndk and tried a hello world android app using ndk once and the three sample projects in question seem to all need native code (thus ndk).
On selecting the project in eclipse the console reads:
<terminated> Native Builder CVCamera_MSER [Program] C:\cygwin\bin\bash.exe
/usr/bin/bash: 1ine 0: cd: /home/Davidchen/opencv/android/apps/cvCamera_MSER: No such file or directory
I tried building the native project using the commands in the command line (as I understood from here):
cd {project path}
{ndk path}/ndk-build
However scores of errors appeared, all reference-related, since there are inumerable references to home/DavidChen. There is no folder on my computer named DavidChen. My guess is that there is a reference somewhere to the project path within the cygwin home folder of the project's author. I still cannot find where this faulty reference is specified however so that I could alter it to an existing one instead; I've looked into the paths and symbols under the C/C++ General Project Properties in eclipse as well as the source files, both native code and java code.
When I've tried it on cgywin's console, it still didn't work.
The errors are upon trying to run the project CVCamera_MSER, under the project video titled Local Feature Points found in the link provided above (also [here][14] for convenience). I've also tried running the projects Edges, Lines, and Circles and Feature Tracking with no success.
I'm using Eclipse Indigo Service Release 2 running on Windows7 x64bit.
Thank you for your time.
Java problems
I am a student of Java. I managed to write about 15 Java programs so far and get them working on the PC. But I have not yet written a init() method like my latest assignment requires in order to initialize some instance variables. The compiler tells me that my init() method is attempting to override the final init() method in the acm.program. Isn’t that what an init() method is supposed to do? After exhausting all avenues on PC for the last week, I thought maybe it is an Eclipse problem on the PC. All the example code in the Java documentation shows little Mac windows. So I thought I would try moving my code to a Mac running Lion OS 10.7.2.
Switching to MAC environment.
The Mac claims to have Java installed but I think it’s just the run time environment, not a development environment. All I could find for applications is the Java VisualVM, which I assume is the virtual machine so there is no java development software. So… I downloaded Eclipse for Mac from Stanford’s website and got Eclipse IDE for Java Developers Version: Helios Service Release 2 and tried to run a simple program which included an import statement.
The import acm.program.*; statement is giving the compiler a problem: "acm cannot be resolved”. After researching this I think the problem is I have not downloaded the acm.jar archive and added that to my build path. Why this isn’t already done for me, as part of Eclipse I have no clue. I guess everything has to be difficult.
So I downloaded the acm.jar archive and it’s sitting in my download folder. I tried double clicking it and thankfully the mac won’t execute it. I tried dragging it into my source folder in Eclipse and then adding it to the build path. Once in the build path, Eclipse tells me the jar is missing. So I removed it from the build path and instead from inside Eclipse went to Properties/Java Build Path/Libraries/add External JARS… and navigated to my downloads folder where the acm.jar folder is to select the JAR. However, Eclipse seems to be looking for a .jar;.zip file, which there are none because my Mac helpfully already unzipped the folder. So I changed the open window to look for all files (.) and now I see individual .java files that are too numerous to add to the build path individually.
So back to the PC and download the acm.jar zip file and copy it over to the Mac in unzipped form and again add it to the build path as a zip file. This resolved the compiler error and my simple program executed on the Mac!
Next I will try my program with the init() method to see if that now works. Nope. Same problem on the Mac. This init method causes the following error: Multiple markers at this line
overrides acm.program.Program.init
Cannot override the final method from
Program
public void init() {
canvas = new HangmanCanvas();
add(canvas);
}
Does it have to be this hard or am I missing something?
Generally Macs have the whole JDK installed. Eclipse is nice, though.
This "acm" package isn't installed because it's not any kind of standard thing; this is like asking why your refrigerator doesn't come with asparagus already in it.
That last dialog was the right one; you need the original jar file. Try again, right-click and "Save As..." the link to save the file from your browser.
See 3. I find it particularly funny that anybody would use a Windows computer to make up for shortcomings of a Mac; in reality the Mac is infinitely more flexible and more powerful.
If you got a message that complains you're trying to override a final method, then you are indeed trying to do something wrong; final actually means "You're not allowed to override this." Perhaps you didn't fully understand the instructions for the assignment.
It gets better, I promise. Just be sure to use each of these annoyances as a learning experience.
There is no reasons why Java for the Mac would be any better than Java for the PC. The language and tools should work the same ... assuming that you are using the same versions of the language and similar versions of the tools.
Your problem with init is nothing to do with PCs versus Macs. So don't waste your time switching platforms to try to fix it. You need to figure out what the
On the face of is, the compiler / IDE is telling you the truth. Java won't let you override a final method. In fact the whole point of declaring a method to be final is to prevent overloading.
However, this does not make sense. According to the documentation I found here, the acm.program.Program.init() method is designed to be overridden. So why won't it let you?
I suspect that the cause of your problems is that you've downloaded or been given a copy of the JAR file that someone has messed around with. Someone has changes the method to be final (for some reason best kown to themselves), compiled it and put it up for people to download. Google is not always your friend ...
So, what I suggest you do is review all of the handouts and the files that were provided to find either the copy of the JAR that is provided, or the instructions on WHERE to download it from. Then replace the copy of the JAR you are currently using with the recommended one.
Why this isn’t already done for me, as part of Eclipse I have no clue. I guess everything has to be difficult.
How is Eclipse supposed to know what this "acm" stuff is? Which version you require? Where to download it from?
Have been trying out Web2Py for a couple of days now and I decided it to be a keeper. But there is one thing that concerns me a lot and that might be a showstopper in the end. I need a nice development environment & setup I can trust and be productive with. Coming from the MS Visual Studio world I'm looking for something with good autocomplete / intellisense + functions for versioning and deployment.
I did some attempts to edit my code in Eclipse but it needs additional setup to run with autocomplete, and for debugging I dont know if it's possible. (Noticed there was a Django project template in Eclipse which is a bit tempting I must say.)
Wing Ide has a instruction on how to get web2py up and running and I am up to testing that one. Not free, but very cheap compared to much in the Windows world.
I also want a good versioning (hg) setup, and preferably a semi-automatic FTP-deployment-method.
What IDE do Web2Py developers use, and how do your setup look like?
A complete setup script for a project in a good IDE would be awesome! (Just like the installation is, one click to get it running 100%).
Pycharm looks good, perhaps that one can add web2py support http://youtrack.jetbrains.net/issue/PY-1648
Thanks a lot!
OS: Windows 7/Windows XP
IDE: NetBeans
Version control: TortoiseHg/NetBeans
Debugger: winpdb
Shell: IPython
Publish: WinSCP/PuTTY/TortoiseHg
Scripts
Once I create a new project in web2py I add a few scripts to my main app folder:
web2py\applications\myapp\DebugWinpdb.bat:
C:\Python25\Scripts\winpdb.bat ..\..\web2py.py -i 127.0.0.1 -p8000 -mypassword
web2py\applications\myapp\DebugShell.bat:
C:\Python25\Scripts\winpdb.bat ..\..\web2py.py -S myapp -M
web2py\applications\myapp\Shell.bat:
python ..\..\web2py.py -S myapp -M
IDE
As others have stated you need to do some extra stuff to get autocomplete/intellisense for web2py no matter what IDE you use.
For me NetBeans was a good compromise between does-everything-if-only-you-can-figure-out-how (Eclipse/PyDev) and does-the-basics-but-few-extras (PyScripter).
NetBeans Setup (Project Properties):
Python Category
Python Platform: Python 2.x (default is Jython)
Run Category
Main Module: web2py.py
Application Arguments: -i 127.0.0.1 -p 8000 -a mypassword
NetBeans Pros:
Tight Mercurial integration
Highlights which lines have been added, changed, or deleted in your source file as you edit it
Selective rollback of individual changes you've made since your last commit
One of the nicest visual diff viewers I have used
Python PEP8 style hints (fully customizable)
Name "foo" is not a valid class name according to your code style (CapitalizedWords)
Name "Bar" is not a valid function name according to your code style (lowercase_with_underscores)
Auto-format hotkey (corrects spacing around operators, etc)
Navigation within source file
semantically indexes current source file
organizes alphabetically by type (Class, method, attribute, etc)
makes even enormous style sheets manageable
NetBeans Cons:
Integrated Debugger doesn't work with web2py (that one really hurts)
Long startup time (but acceptably snappy for me once up and running)
Version Control
I use and highly recommend Mercurial for source control. As mentioned earlier, NetBeans has great support for Mercurial but there are some things I'd just rather do in TortoiseHg.
TortoiseHg Pros:
Shell overlay icons
Repository Explorer
view repos history with graphical display of branching/merging
one stop shop for Incoming, Outgoing, Push, Pull, Update, etc with button for Commit tool
Commit tool
Hunk Selection: cherry pick changes from within a file for more focused Commits
Add, Remove, Diff, Revert, Move, Remove, Forget
TortoiseHg Cons:
No easy way to drop directly into a command line
Bug that regularly prevents files from being removed during commit (waits indef for a lock to be released; running hg addremove from command line is a reliable workaround)
Publishing
I use a combination of WinSCP (for browsing), PuTTY (for terminal commands), and TortoiseHg (for push/pull of my repos) to work with my shared hosting account on Webfaction.
The first thing I do is set up public/private key encryption. If you are having trouble getting this set up between Windows and Linux, try these instructions from Andre Molnar. Short story is you need to generate your private key using ssh-keygen on Linux, copy it down to your Windows machine using WinSCP, then convert it for use with WinSCP and PuTTY.
Then add the following lines to your global mercurial.ini file:
[ui]
ssh = "C:\Program Files\TortoiseHg\TortoisePlink.exe" -ssh -2 -i "c:\path\to\your\privatekey.ppk"
Even if you have to connect to multiple servers, you need only copy your public key to each of the different servers. You'll also want to let WinSCP and PuTTY know where your private key is located, but those are fairly easy to figure out.
Try the new web2py admin interface in trunk. It has a web based mercurial interface and a google deploy interface.
In web2py you can edit applications/admin/models/0.py and set
TEXT_EDITOR = 'amy'
And you will get the web based Amy editor with autocompletion. It is not default because because it does not work with some browsers and because autocompletion is not as good as eclipse. It may work for you.
You can use web2py with Eclipse but you need a minor workaround to let Eclipse know about the web2py environment. It is explained here.
I know other users have used other IDEs with web2py, for example WinIDE and pyCharm. I suggest you ask on the web2py mailing list where people are very helpful.
I'm pretty sure that the 'one-click setup script' to do all that you are looking for does not exist (at the moment). But don't be put off - you can achieve a nice development environment to suit your needs and there are lots of choices.
Although I develop on Windows, I like the setup I have as it's more of a 'Unixy' way of thinking whereby I have a number of tools each doing a specific task. Once you get a workflow setup you can be very productive - although I realise it may look a bit confusing initially coming from a Visual Studio world.
Below I outline what I've settled on. I'm sure others will have their own recommendations. Pick the options you like best.
(There should be hyperlinks to useful software below but I don't have enough reputation to include more than 1 link...)
For developing on Windows I'm enjoying using Pyscripter. It's free, fast (compared to Aptana / Eclipse / Netbeans etc) and has some nice features (dark theme, integrated python console and code explorer to name a few).
To get code completion / intellisense to work for web2py you need to add some code to your model / controller files because of the way web2py works. There are some instructions in this discussion topic on the web2py group.
web2py has a great error ticketing system built in (see the web2py book chapter 3). For more comprehensive debugging, pydb seems to be the way to go. Just put the code below as a breakpoint:
import pydb
pydb.debugger()
and it'll take you to the debugger.
I use TortoiseHg for Mercurial integration and it works wonderfully. Combine that with winscp and you can deploy easily.
Caveats: I work in OS X, and do most of my coding in BBEdit.
That said, I've used both Wing and Komodo IDE for web2py debugging, and they've both worked quite well for me. I haven't tried NetBeans in a while now; when I did the Python support seemed a little rough around the edges. And I've never had the time or patience to come up to speed with Eclipse; it's filed in my mental file cabinet with Emacs, no doubt unjustly to Eclipse and/or Emacs.
(And I'll echo mdipierro's recommendation to try the web2py mailing list; it's really indispensable--one of web2py's strongest points.)
Have you considered using fewer tools? Both Python and web2py don't require a whole lot of code to get a lot accomplished. web2py only adds 10 or 15 new function calls (besides the HTML helpers and validators). You might find that Eclipse and other IDEs actually get in the way. Setting up new apps in web2py is simple through the admin system. Since the new app scaffolding copies the welcome app, you can customize new app setup by editing the welcome app. With Mercurial (or Git, Subversion or Bazaar) you can set up a server on your machine or with one of the public sites and either push or pull updates to your production server. Keep it simple, I say.
we are using web2py framework for all our web application needs and this is our setup :
OS - Ubuntu up-to-date
IDE - Aptana Studio 3.0 with pyDev
Version Control - git
Python 2.7
Browser for developing phase : Chrome
I've found the Wing IDE debugger to be very useful. It's a powerful debugger across the board, and also can be configured to do remote debugging, which is really important when you are running web2py on a no-GUI remote machine (e.g. at Amazon Web Services).
I know there are posts that ask how one stores third-party libraries into source control (such as this and this). While those are great answers, I still can't find the answer to this:
How do you store third-party middleware/frameworks binaries that need to alter your compiler / IDE for the library to work properly? Note: for my needs, I don't need to store the middleware source, I only store header files / lib / JAR ..so that it's ready to be linked.
Typically, you simply link libraries to your app, and you are good. But what about middleware / frameworks that need more?
Specific examples:
Qt moc pre-processor.
ZeroC Ice Slice (ice) compiler (similar to CORBA IDL preprocessor).
Basically these frameworks/middleware need to generate their own code before your application can link to it.
From the point of view of the developer, ideally he wants to just checkout, and everything should be ready to go. But then my IDE/compiler will not be setup properly yet, so the compilation will fail..
What do you think?
Backup everything including the setup of the IDE, operating system, etc. This is what i do
1) Store all 3rd party libraries in source control. I have a branch for all the libraries.
2) Backup the entire tool chain which was used to build. This includes every tool. Each tool is installed into the same directory on each developers computer, so this makes it simple to setup a developers machine remotely.
3) This is the most hardcore, but prepare 1 perfect developer IDE setup which is clean, then make a VMWare / VirtualPC image out of it. This will be useful when you cant seem to get the installers to work in future.
I learned this lesson the painful way because I often have to wade through visual studio 6 code which don't build properly.
I think that a better solution is to make sure that the build is self-contained and downloads all necessary software for itself unless you tell it otherwise. This is the way maven works, and it is really handy. The downside is that it sometimes needs to download a application server or similar, which is highly unpractical, but at least the build succeeds and it becomes the new developers responsibility to improve the build if needed.
This does of course not work great if your software needs attended installs, but I would try to avoid any such dependencies in any case. You can add alternative routes (e.g the ant script compiles the code if eclipse hasn't done it yet). If this is not feasible, an alternative option is to fail with a clear indication of what went wrong (e.g 'CORBA_COMPILER_HOME' not set, please set and try again').
All that said, the most complete solution is of course to ship everything with your app (i.e OS, IDE, the works), but I doubt that that is applicable in the general case, how would you feel about that type of requirements to build a software product? It also limits people who want to adapt your software to new platforms.
What about adding 1 step.
A nant script which is started with a bat file. The developer would only have to execute one .bat file, the bat file could start nant, and the Nant script could be made to do anything you need.
This is actually a pretty subtle question. You're talking about how to manage features of the environment which are necessary in order to allow your build to proceed. In this case it's the top level of your code toolchain, but the problem can be generalised to include the entire toolchain, and even key aspects of the operating system.
In my place of work, we have various requirements of the underlying operating system before our code will successfully run. This includes machine-specific configurations as well as ensuring correct versions of system libraries and language runtimes are present. We've dealt with this by maintaining a standard generic build machine image which contains the toolchain requirements we need. We can push this out to a virgin machine and get a basic environment that contains the complete toolchain and any auxiliary programs.
We then use fsvs to version control any additional configuration, which can be layered on to specific groups of machines as needed.
Finally, we use custom scripts hooked in to our CI server (we use Hudson) to perform any pre-processing steps required for specific projects.
The main advantages for us of this approach is:
We can build and deploy developer and production machines very easily (and have IT handle this side of the problem).
We can easily replace failed machines.
We have a known environment for testing (we install everything to a simulated 'production server' before going live).
We (the software team) version control critical configuration details and any explicit pre-processing steps.
I would outsource the task of building the midleware to a specialized build server and only include the binary output as regular 3rd party dependencies under source control.
If this strategy can be successfully applied depends on whether all developers need to be able to change midleware code and recompile it frequently. But this issue could also be solved via a Continous Integration Server like Teamcity that allows to create private builds.
Your build process would look like the following:
Middleware repo containing middleware code
Build server, building middleware
Push middleware build output to project repository as 3rd party references
Update: This doesn't really answer how to modify the IDE. It's just a sort-of Maven replacement thingy for C++/Python/Java. You shouldn't need to modify the IDE to build stuff, if so, you need a different IDE or a system that generates/modifies IDE files for you. (See CMake for a cross-platform c/c++ project file generator.)
I've written a system (first in Ant/Beanshell at two different places, then rewrote it in Python at my current job) where third-partys are compiled separately (by someone), stored and shared via HTTP.
Somewhat hurried description follows:
Upon start, the build system looks through all modules in repo, executes each module's setup target, which downloads the specific version of a third-party lib or app that the current code revision uses. These are then unzipped, PATH/INCLUDE etc are added to (or, for small libs, copy them to a single directory for the current repo) and then launches Visual Studio with /useenv.
Each module's file check for stuff that it needs, and if it needs installing and licensing, such as Visual Studio, Matlab or Maya, that must be on the local computer. If that's not there, the cmd-file will fail with a nice error message. This way, you can also check that the correct version is in there
So there are a number of directories on the local disk involved. %work% needs to be set using an global environment variable, preferrable on a different disk than system or source-checkout, at least if doing heavy C++.
%work% <- local store for all temp files, unzip, and for each working copy's temp files
%work%/_cache <- downloaded zips (2 gb)
%work%/_local <- local zips (for development or retrieved in other manners while travvelling)
%work%/_unzip <- unzips of files in _cache (10 gb)
%work%&_content <- textures/3d models and other big files (syncronized manually, this is 5 gb today, not suitable for VC either)
%work%/D_trunk/ <- store for working copy checked out to d:/trunk
%work%/E_branches/v2 <- store for working copy checked out to e:/branches/v2
So, if trunk uses Boost 1.37 and branches/v2 uses 1.39, both boost-1.39 and boost-1.37 reside in /_cache/ (as zips) and /_unzip/ (as raw files).
When starting visual studio using bat files from d:/trunk/BuildSystem/Visual Studio.cmd, INCLUDE points to /_unzip/boost-1.37, while if runnig e:/branches/v2/BuildSystem/Visual Studio.cmd, INCLUDE points to /_unzip/boost-1.39.
In the repo, only a small set of bootstrap binaries need to be stored (i.e. wget and 7z).
We currently download about 2 gb of packed data, which is unzipped to 10 gb (pdb files are huge!), so keeping this out of source control is essential. Having this system allows us to keep the repo size small enough to use DVCS such as Mercurial (or Git) instead of SVN, which is very nice. (I'm thinking of using Mercurials bigfiles extension or file sharing instead of a separately http-served directory.)
It work flawlessly. Developers need only to check out, set an enviroment variable for their local cache, then run Visual Studio via a specific batch-file in the repo. No unzipping or compiling or stuff. A new developer can set up his computer in no time. (Installing Visual Studio takes the order of a magnitude more time.)
First time on a new computer takes some time, but then it's fast, only a few seconds. Downloads/unzips are shared on the local computer, do checking out additional branches/versions does not occupy more space. Working offline is also possible, you just need to get the zip files manually if new ones have been uploaded. (This mechanism is essential to test new versions/compilations of third-party libraries.)
The basics are in a repo on bitbucket but it needs more work before it's ready for the public. Apart from doc and polish, I plan to:
extend it to use cmake instead of raw
vcproj-files, to make it more
cross-platform.
script the entire
process from checkout/download of
third-party packages to building and
zipping them (including storing the
download in a local repo) ... currently that's on my dev computer. Not good. Will fix. :)
As for moc, we use Qt's Visual Studio add-in, which stores this in the .vcproj files. Works well. I do think that CMake is one of the best answers for this though
