Sorry if this is a dumb question but for the life of me I can't figure out how to run this eclipse rcp application (https://github.com/neo4j/neoclipse/downloads) on ubuntu 11.04.
Let's suppose that your computer has a 32-bit Intel or AMD processor.
You'll be using a terminal such as Gnome Terminal.
First make sure some "java" program is available by typing "which java". If not, install openjdk, or some equivalent if you know which one you want.
Then download neoclipse-1.6-linux.gtk.x86.zip, perhaps via "curl -L https://github.com/downloads/neo4j/neoclipse/neoclipse-1.6-linux.gtk.x86.zip > neoclipse-1.6.linux.gtk.x86.zip"
"unzip neoclipse-1.6.linux.gtk.x86.zip"
"chmod u+x neoclipse-1.6-linux.gtk.x86/neoclipse-1.6-linux.gtk.x86/neoclipse".
"neoclipse-1.6-linux.gtk.x86/neoclipse-1.6-linux.gtk.x86/neoclipse".
If some part of these instructions presents a difficulty, please clarify.

I'm trying to install Scalatra on windows seven and need to change a file to executable...the Scalatra documentation says to do this, which is unix. What is the windows equivalant?
chmod u+x srt
You can simply open the relevant folder with a unix command prompt (I use git bash) and execute the unix commands from there
To get scalatra-sbt going on Windows, either port you own sbt.bat from scalatra-sbt, or install chmod via cygwin.
Assuming you've successfully installed the rest of Conscript and giter8, you can start a project that downloads scalatra-sbt. From there, one can look through the ./sbt source, and port the bash script functionality to your own windows specific script, or install a unix compatibility layer into Windows. If you go down the "windows specific script" route, perhaps the scalatra-sbt would appreciate the project contribution.
The "unix compatibility layer" route will eventually allow you to run ./sbt. chmod is a unix command line function, and is provided in a default package of the tool set cygwin, which provides a complete lunix-like environment. Once inside a cygwin terminal, you can chmod your file, as mentioned in the scalatra-sbt first project.
Diving into the contents of ./sbt from scalatra-sbt, this is actually unix script wrapper around the scala build tool (also referred to, confusingly, as sbt). If while trying to run ./sbt you get strange '\r' errors, install the cygwin package dos2unix, and then run it on the sbt file. If you run into any "which: no curl in..." or "which: no wget in..." errors, go back to the cygwin installer, find those packages such as wget, and then install those programs.
By the way, the last thing the scalatra-sbt script runs is the Scala build tool. The Scala build tool sbt itself has many reported issues with cygwin's default configuration, so you will likely need to do more research. Depending on what issues you're running into on your specific setup, you may need to make changes to the end of the ./sbt script to adjust the parameters used to launch the Scala build tool.
hey everyone I am just starting to use c++11, which I need for uni, a have a mac and I am familiarise with eclipse (I have both Juno or Kepler with CDT), but as much as I tried I can not run properly any c++11 features in eclipse or compile any code, there is someone that has been in my same position and please help me, seriously I already try all the previous threads about, but for my frustration i am still compiling everything on terminal and editing all in gedit with is not the most confortable way, by the way I have to compile with g++-4.7 as command not g++ meaning that still I have the old OS gnu,please someone just explain me step by step what to do I am terribly frustrated, I beg!!!!
ps. just clarify i install gcc 4.7 with homebrew but the path is different than the original (/usr/local/bin instead of the regular /usr/bin which I believe eclipse use and the reason I can't work with it, thank you for all guys)
Well after trying different things and expending tedious time fixing my issue I will answer my own question with the hope someone with my same needs will not experiment such annoying situation.
First as in a lot of forums remark and is well know the gcc compiler provided for the Mac OS is old and obsolete (more than 5 years old is a lot in computing terms), so first step to work with c++11 is to get a new version of the gcc.
There are two options with the packets common managers (homebrew and macports), I have to say that I was that frustrated that i tried both to see if was a problem of the version in the packet manager even thought should be the same, but for my surprise there is a small difference which later I will explain, which bring me to suggest use macport because with macports the eclipse will work as smooth as with the old c++ while with the installation with homebrew the compilation will be the same than the macport but eclipse will complain about the new grammar in the c++11 (eclipse will tell you that the resource couldn't be resolve, even do compile properly ).
The steps for this are assuming you have the command line already:
download the appropriate macports from the official web page(google it)
in terminal type the following commands
sudo port selfupdate
sudo port upgrade outdated
sudo port install -d gcc47
port select --list gcc
with this you have gcc and will show you which are the gcc installed in you mac now just missing select as defauld the new gcc, do it with.
- sudo port select gcc mp-gcc47
3 having install in my case eclipse kepler create a new C++ project, but instead to left everything standar do the next:
- in the wizard window select as toolchain the cross GCC as the toolchain(for example ni the executable Hello World c++ project), put a random name and next , following window press next now here in the window for the selection of the compiler give the path for the new gcc(the default is /opt/local/bin) as prefix leave it empty and press now the finish bottom.
4 Now go to project properties and in c/c++ build select settings and in the tool settings tab go to miscellaneous in cross g++ compiler and in other flags add -std=c++11.
5 by the last go to c/c++ general -> paths and symbols and select the tab symbols and in select the gnu c++ language and press add to type GXX_EXPERIMENTAL_CXX0X as name just that and press ok.
Now just press apply and ok, after that your mac should be running c++11 in eclipse.
Hope works for you as for me see you around guys.
Note probably you will be to configurate the run but it is more simpler than you thing just go to run -> run configurations and double click in c/c++ application now almost everything is generate for you just you have to fill up the first label with the path to the out put of the compiler (I asumme that you already build the project which will generate the executable file ) normally that file is in the debug folder of the project with the same name than the file compiled n does all.
have a good one guys.
I am new to Linux. I am trying to develop ROS application using eclipse. I don't understand the below which is provided in ROS website. Can you explain this in more simple way, So that I can configure my eclipse after downloading from eclipse.org.
Reusing your shell's environment
For building and running ROS programs from inside IDEs, the ROS
enviroment has to be set up. All IDEs might have a config for that,
but running your IDE from your ROS-sourced shell should be the easiest
way, avoiding inconsistency.
Likewise, you can enhance your IDE's launcher icon to load your shells
environment. E.g., replace its command eclipse with
bash -i -c "eclipse". This will make bash source
~/.bashrc, in which ROS has to
be sourced and parameterized, and start that IDE.
use following commands:
cd <your_catkin_workspace>
catkin_make --force-cmake -G"Eclipse CDT4 - Unix Makefiles"
cd build
cmake ../src -DCMAKE_BUILD_TYPE=Debug
now you can import your project to eclipse
after that you can create a desktop application entry for eclispe:
sudo vim /usr/share/applications/eclipse.desktop
[Desktop Entry]
Type=Application
Terminal=false
Icon=<path_to_your_eclipse_dir>/icon.xpm
Exec=bash -i -c "source /opt/ros/hydro/setup.bash && source $HOME/workspace/<your_catkin_workspace>/devel/setup.bash && <path_to_your_eclipse_dir>/eclipse"
Comment=IDE
Name=eclipse
Comment=IDE
It seems that a wiki was published about this subject here
Put simply, the lines you listed are suggesting you run your IDE (eclipse) from a terminal which has already been sourced. So for instance, if you have a package called mypackage, you might type in a terminal:
cd ~/mypackage
source devel/setup.bash
eclipse
The first line is just however you get to your package, the second line sets up environmental variables for you (like changing your PATH), then you can run eclipse with all of those already setup so you don't have to configure your package in eclipse 100% manually.
I have created an application in linux with GTK2 as GUI. It uses some linux-specific headers (e.g. arpa/inet.h) so to run under Windows I have to compile it with Cygwin. I downloaded the latest installer and choose to install GTK2 and its dependencies. My program compiled fine. But it needs X server to be running! I has old-style, ugly graphics and it doesn't open in a different window, like all Windows' applications do, but inside X server's window. Because of this it can't be portable. I found that guide, which is exactly what I need, but I get an error when I run "make" for GTK2 (undefined reference for _IID_IFilePersist, although I have uuid installed - also tried it with gtk2.20). Can you suggest what to do to build my application with cygwin? Or what do I need to install for the "_IID_IFilePersist" error? Thanks in advance!
There's prebuilt packages for windows that doesn't rely on X. http://gtk-win.sourceforge.net/home/index.php/Downloads
If you don't want X server to be running, then you're going to have to port the linux-specific parts of your code and compile with MinGW rather than Cygwin.
I just got this MSI wind netbook and tried to run eclipse on it. I installed JDK6 on the netbook already. Whenever I open eclipse there is nothing show up on the screen except a "warning sound" that alerts. What is the problem here?
ps.I just started learning java.
Most likely the Eclipse starter program can't find where you installed Java. Since Eclipse is a Java program, it needs a JRE installed (comes with the JDK typically) to run. Assuming you're running Windows on your MSI Wind, check to make sure the java executable is on your path in your computer environment settings (windows key + printscreen button, or windows key + pause button are the shortcuts to open the computer properties dialog if I remember correctly. Then go to advanced).
You can test if java is on the path by opening a cmd.exe shell window and typing 'java'. If it says it cannot find java, then you need to fix the path.
See this link for additional troubleshooting details: http://www.eclipsezone.com/eclipse/forums/t99010.html
You could try reinstalling the JDK. Perhaps having it on a different disk than the default (D: versus C:) is causing some trouble? It certainly isn't a problem with the hardware, I'm running Eclipse on Windows on an MSI Wind.
Use "Add/Remove programs" in the control panel to remove the java versions you have installed.
Then visit "java.com" and use it to install Java, and verify that it is working. You do not need more than that to use Eclipse.
