We have defined our own ADD_EXECUTABLE macro (TDS_ADD_EXECUTABLE) for our cmake files which handles some nice internal functionality for us.
The problem is, when I load up our project in KDevelop 4 (linux) while it finds and builds our entire system, it does not add any of the executables to the Project Targets list for configuring the launches. This makes it a real management nightmare to do any work in KDevelop since we have to manually add all of our executables.
Is there a way to tell KDevelop our TDS_ADD_EXECUTABLE performs an ADD_EXECUTABLE... or something like this? I was actually surprised it was unable to fathom this on it's own since it's all scripted.
Any help is appreciated, thank you!
Do I understand this correctly - TDS_ADD_EXECUTABLE is just a macro around ADD_EXECUTABLE? If so, KDevelop should figure that out automagically. Post a small testcase to the correct place: http://bugs.kde.org

I'm looking at using Tesseract to do some work with PDF files, and so I want to use the library rather than an external executable.
I started by downloading the full Tesseract source and looking at building that. Sadly the standard sources don't have any means to build on a non-Linux platform, in my case Windows. There are methods for doing so, and I looked at those.
Firstly the VS2008 build doesn't. I'm aware that it need Leptonica, but I figured I'd tackle that afterwards and just tried to build the existing code. Fails with "fatal error C1083: Cannot open include file: 'allheaders.h': No such file or directory". Nothing to do with Leptonica at this stage, it simply doesn't work.
Even if I were able to get past that, I'd have to build Leptonica, and that requires using GNU tools and therefore an installation of Cygwin, so I gave up. I Have a MingW instatllation, (I've never managed to get Cygwin to work in a usable fashion) but I'm not keen enough to mess with such a complicated and fragile build.
So I decided I'd just use the pre-built binaries which some kind soul creates. Downloaded that from code.google.com. Now I need to look into using the code, so the next obvious step is the Tesseract API example, which states it requires "tesseract-ocr-3.02.02-win32-lib-include-dirs.zip", no problem, because I already have that now.
No real clue as to where the API example wants the files to be placed, but a little messing about gets them in appropriate locations. Press build and "fatal error C1083: Cannot open include file: 'allheaders.h': No such file or directory", just like trying to build Tesseract from source.....
And indeed there is no such file.
So, where is this file ?
I also struggled some time ago to make it works under windows and then I found this git repository : https://github.com/charlesw/tesseract-vs2012
It includes all needed extern library (because Tesseract need Leptonica, but Leptonica also need extern library to handle the different image format) and is also working great with vs 2013.
OK so now I see that allheaders.h is part of Leptonica. Still leaves me wondering why the Tesseract pre-built library requires that I have Leptonica available, I would have expected that to be built-in, I guess it isn't.
so once again, I'm having a little problem I can't figure out myself. Meaning, I'm pretty sure I know what the problem is, I just can't fix it.
I'm developing in C++ using Netbeans 7.01 with CMake 2.8.6. However, when I'm trying to build a project, I get the following error from CMake:
CMake Error: The path to the source directory:
H:/Projects/Netbeans/CppApplication_1/CONF=Release
contains unsupported character '='.
Please use a different source directory name.
Please note, that "CONF=Release" isn't a folder. It seems to be a configuration flag set by Netbeans, as it changes when I'm trying a debug build. So, my guess here is, that theres a space missing, or something similar. Unfortunately, I can't figure out where to change that. There are no options in any related Netbeans window, I can't find anything related in the configuration files for netbeans itself or the project either.
Did anyone here have experienced the same problem and found a solution to it? I would be very glad to hear it. If there's any information missing, let me know, I will add them as fast as possible.
Edit:
Just noticed there is already version 7.1 of netbeans, nice to know. However, even with this version, the same problem occurs.
You must specify the command you ran to allow for the error to be identified. However, it looks like you missed the "source-path" parameter.
The cmake command ends with the path to source and should be something like:
cmake -D CONF=Release <path to source>
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?
I've been trying to build some huge projects in BCB5 for some time now. I want to use the command line tools because it would cut build time by more than 50% (it already takes 4 hours in the IDE). Often, projects will build just fine in the IDE but fail miserably in the command line. I did some digging and discovered this nice little comment in a header file:
__published: // IDE-managed Components
Is this saying that the components that follow can only be built with the IDE open? Please tell me there is a way around this. BCB5 is starting to make me depressed.
Extra info:
Make.exe gives a pile of errors claiming ambiguity between the header file and an imported file. I''m pretty sure the header file is supposed to be referencing the imported file though, rather than comparing with it.
In the header file:
#include <ComCtrls.hpp>
ComCtrls.hpp has the variable TTreeNode.
Error from make:
[exec] Error E2015 .\TMain.h 876: Ambiguity between 'TTreeNode' and 'Comctrls::TTreeNode'
__published: // IDE-managed Components Is this saying that the
components that follow can only be
built with the IDE open? Please tell
me there is a way around this. BCB5 is
starting to make me depressed.
No, this does not mean that you can only build the source in the IDE. It just means that this section is automatically populated by the IDE (the form designer)
While there are good third party solutions (as mentioned by the others) C++Builder 2007 and above made huge improvements in the build system. IDE build times are very similar to command line builds and the MSBuild integration now makes it possible to be sure that the same parameters are passed to the command line tools as are used by the IDE.
Have you tried installing the C++ Compiler Enhancements plugin, by Andreas Hausladen, which improves the compilation speed. I would also recommend installing the DelphiSpeedUp plugin.
I think you need to export the project as makefile, to compile from the command line, because C++Builder 5 project files are XML. Have a look at this article, from the C++Builder Developer's Journal.
If none of the above fails try the official C++Builder Forum.
I've more or less given up on the BCB5 command line tools. It appears that they are fundamentally broken.
I did, however, manage to find a nice open source tool, ProjectMaker, that uses the command line tools effectively. You can find it here: http://projectmaker.jomitech.com.
ProjectMaker fixes up a few of the problems with BPR2MAK, but it's not perfect. Most project build perfectly with ProjectMaker, some still require the IDE. It's not a perfect solution, but it does alright.
I have been used to working with VS2005 and 2008 - using msbuild, etc, but I have inherited a set of projects that have to remain in vc6.0 for now. I don't like opening each project in the developer studio and building. I prefer to build form command line (I am automating the builds). Is this possible?
I have tried the nmake utility, but I still need to open up the projects and save/export the make file. This is tedious if the project changes - each time I have to save the make file. nmake seems to work, but it had a problem when I changed the location of the project in my directory tree (I checked out of svn into a new clean dir to try the build). It seemed to have hard coded paths in it, but I will have to check on that - it might have been a different problem.
Any alternatives out there?
Eventually I will migrate these to 2008, but for now that is not an option.
I'm recording the most important part of your link here - Microsoft has a bad habit of moving stuff around and leaving dead links. Not only is this the most important bit, but it gives enough information to do a search if/when they move it.
Building a Project from the Command Line
You can build a Visual C++ project from the command line without first exporting a makefile (MAKEFILE, or filename.mak) and using the NMAKE utility.
The basic command syntax is
msdev FileName [/MAKE "ProjectName – ConfigName | ALL"] [/REBUILD /CLEAN /NORECURSE /OUT LogFile /USEENV]
where FileName is the name of your project (.dsp) or workspace (.dsw) file.

thanks all
of course you can automate. I haven't used vc in years, but I think the compiler is called c8.exe or wow, I can't remember silly little tidbits like that anymore, but look in your vc\bin directory at all the exes and it will be obvious by name.
you can write a batch file worst case. But I also remember the UI having a "create makefile" function. So you do that once, and then just run make from the command line and voila. or maybe it's nmake. Again, been a long long time.
Microsoft provides a command line driver for building Visual Studio projects. In VC6 it's called "msdev" (do msdev /? for a list of options).
At some point (probably VS.NET/VS 2002) they started calling the command line build driver "devenv" for some reason. It has a somewhat different syntax, but for driving builds the options are the same or similar.
We use automated builds at my work place. Essentially just a batch file i fire off from the command line. Let me make sure i am allowed to post some sample code before i go ahead and post it. But yes, it IS possible to automate the build.
Sample Code:
:::::::: CompileSolution :::::::::::::::::::::::::
call X:\BuildTools\bin\BuildVbProj.bat
%COMPONENTNAME% %SOLUTIONDIR%
%PROJFILE% %BUILDOUTPUTFILE%
%PREBUILDFILE% if %ERRORLEVEL% NEQ 0
goto BuildErrors
goto Cleanup
EDIT: The BuildVbProj.bat file ultimately calls VB6.exe in the Program Files\MS Visual Studio\VB98\ folder. Try calling it with "VB6.exe /?" or "VB6.exe -?" and it will show you a list of options. You can basically automate your process using those options.
There should be a similar exe for VC in the VC98 folder as well.
Another option which is less labor intensive is
Pulldown Menu (BUILD)
Select (BATCHBUILD)
Push Button (REBUILDALL)
