Title: build options for targets being developed in both windows and linux
Post by: vri on January 27, 2009, 03:14:26 pm
We are working on a project for an app that should run in both windows and linux. Development is being done on both platforms, using gcc and mingw. Codeblocks is great for this!
I have a small problem, however. We make use of boost and some other libs. Under windows, I need to set a -I option for the include path for that, I do this using a global variable $(#boost). Under linux, this is not needed. The unfortunate thing is that if I open the project under linux, CB insists on setting a global variable $(#boost), which I'd rather not do. Actually, I have a whole list of them in my workspace, and I seem to be unable to continue in a decent way unless I do specify them.
So my question is two-fold: - can I specify compiler options (-I) and/or linker options in a project for a specific platform only (without making the target compiler-specific, which is undesired in my case)? - can I somehow ignore or invalidate global variables when opening a project or workspace?
Thanks, Theo.
P.S. CB 8.02, gcc & mingw, XP and ArchLinux

You can try to use something like this as search-directory:

Sorry to bother you again...
Yesterday it worked... This morning, I upgraded my linux box to gcc 4.3.3 And now, it apparently doesn't work anymore. It seems that the empty compiler directive "-I" that results on linux leads to problems during the linking step afterwards. I get errors like "multiple definitions of `_start' ".
Any ideas?
Theo.

Sigh... how obvious...
and I pretend to be a programmer...
Thanks again!
Theo.

Further answering my own question: I remembered having read about this before, just didn't manage to find the thread. But now I did: http://forums.codeblocks.org/index.php/topic,8643.msg63221.html#msg63221 (http://forums.codeblocks.org/index.php/topic,8643.msg63221.html#msg63221)
