Title: Cannot build cb from source
Post by: smallB on October 29, 2011, 08:19:40 pm

Guys I followed http://www.codeblocks.org/downloads/7 and after exporting src to my hard drive I've opened codeblocks.cbp. After pressing build I'm getting following error:
C:\...\build_tools\autorevision\autorevision.cpp|108|error: 'pclose' was not declared in this scope|
What am I doing wrong?

It works fine for me...

Here are several things to try.  (I do not believe any of them could have caused this problem, but it does not hurt to check.)
Is svn in you path environment (autorevision tries to use this, but it should work without)?
Have cleaned the project?
Are your global variables correctly setup?
Have you checked for changes to the source code:
svn update
svn diff

You apparently can't compile CB with the -std=c++0x (and maybe other strict ANSI) option. See http://forums.codeblocks.org/index.php?topic=10003.0

@Neil Hi, After switching off some of the options like no -std=c++0x anymore, I'm getting:
 (invalid)\include||No such file or directory [enabled by default]|
 (invalid)\contrib\include||No such file or directory [enabled by default]|
 (invalid)\lib\gcc_dll\mswu||No such file or directory [enabled by default]|
Where am I suppose to get those folders from?

Have you installed wxwidgets?

Neil, no I don't think I did. I'm sorry for this. Is there any particular ver. of wxwidgets I'm supposed to install or the latest one is ok?

Ok I've installed wxwidgets. I've provided search directories to include folder from wxwidgets but I cannot find the other folders in there. Any thoughts?
Thanks.

You need to build wxWidgets, or use wxpack at http://wxpack.sourceforge.net - CB requires wxWidgets 2.8 - it won't build with 2.9 . Reading these instructions http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_Windows might also be a good idea.

Thanks Neil, will try it now.

Neil, I've installed wxPack, I believe that I've set up paths in cb to wxwidgets but still getting those three errors: I don't even have this path:
invalid)\lib\gcc_dll\mswu|

Have you set the CB wx variable as described here http://wiki.codeblocks.org/index.php?title=Installing_Code::Blocks_from_source_on_Windows#Compile_Code::Blocks

Hi Neil, yes, It is indeed set. Now I'm getting following error:
C:\wxWidgets-2.8.12\include\wx\platform.h|196|fatal error: wx/setup.h: No such file or directory|
And indeed there is no such file there. Any ideas why?

Nope, but you can get that problem if you build wxwidgets from scratch. I would expunge all traces of wx from your system (check with a tool like Everything http://www.voidtools.com) and then re-install from the wxpack setup file, but only install the GCC stuff.

Ok will do. Thanks. Tomorrow'll let you know how I got on.
P.S. As you probably've realized there is just one thread with my "ingenious" suggestions ;)

Hi Neil, Great news. Indeed, installing wxPack just for gcc did the trick. Also as you've already mentioned -std=c++0x MUSTN'T be on.
Thanks Neil for your help.
