Code::Blocks command line requires to export DISPLAY

(1/3) > >>

LittleJawa:
I am using Code::Blocks to develop programs that run on both Win32 and Linux.
Then I have two developpment environment, both with Code::Blocks, so that I can switch from one to the other depending on the developpement/debugging issues.
This is perfect, really :-)

Now the bad point...
Sometimes, I just do a simple change on the windows environment, and just want to recompile on the Linux one. I could move to the linux box and log in, but I would rather SSH to it, and do a command-line build. It is far easier and, if I don't need to edit the code, I don't need the graphical environement either.
BUT when I do it, Code::Blocks returns an error saying :

ERROR: Unable to iitialize gtk, is DISPLAY set properly ?

And I cannot go further.

If I use the exact same command line on windows, or on the linux box after login in the X server, then no problem, the build is done. But it opens the build log window, which is probably why I had the error.
Finally, if I install cygwin's X server on my windows box and export the display to it, the build can be done...

This is a problem for me, because my team is preparing to use a build server for the team work, and this build server will not have an X server installed. Then this mean I would not be able to make it build my Code::Blocks projects.
Would it be possible to add an option on command line that says : "I don't want ANY window to get opened" or something like that ?

 I have retrieved C::B source code and looked at it.
 It seems that separating the graphical part from the build part of C::B is really complicated... All the main classes of C::B are derived from wxWidget classes, so it is not possible to load a small subset of the application without having to load/initialize a graphical display of some sort...
 Then having the batch build work on command line though SSH (without X export) is impossible with the current shape of the project.

 I am in the process of locating what part of C::B I would need to get an external build executable that could interprete C::B project files and do the exact same build... Not sure it is feasable :-(
 The next option is to export my projects settings to Makefiles, but this is something that must be automated anyway.
 If anyone can give me advice or ideas, you're welcome.

 I am raising this toppic again, because I have a real need for a "unattended" build.

 My problem actually appears on both Linux and Windows. When I want to use a build software to make scheduled, unattended build, the build process (that calls codeblocks on commandline) is launched by a service. This service have no display (neither on Windows or Linux). On Linux, this makes the process exit. On windows, it just hangs.

 I have tried to set the commandline option that removes the splash screen, but it doesn't help : CodeBlocks' batch process tries to display the log in a new window whatever you do, and it seems to be the cause of the problem.
 On Linux, I was able to cheat by creating a fake X server (using Xvfb) and redirecting the session's DISPLAY to it, but on Windows, I have no clue of what I can do to make the unattended build :-(

 Does anyone have done this successfully ? Do you have any idea I should try ?
 I really appreciate the use of CodeBlocks, but if I fail to use it for builds, I'll have to return to Makefile and the like, with different behavior/setup for each OS, and I really don't want it anymore :-(

 Any help is appreciated.

 Regards,
 Little Jawa

Couldn't you simply run an X server on your Windows box? I've been doing that for years. There are a lot of such servers available - google for "windows x server" for a list.

How do you make CodeBlocks use an X server on the windows host ?
The windows version of CodeBlocks uses Windows display, how do you change that ?
All the X servers that I've seen on Windows allow you to get the remote display of a linux/unix machine, but I don't remember seeing them display the GUI of a windows app...
