Cross Linking of a Linux Project in Windows

(1/2) > >>

apaeffgen:
Hi all,
i am new to Codeblocks /wxWidgets. So maybe the problem is trivial.

On a samba share i have set up a linux CodeBlocks project on Centos, tested some gui-features and build the project for Linux. No Problems so far.

When i open the same project with codeblocks on Windows i get some linker errors.
I use Codeblocks with the mingw included, wxpack and the same project-settings as in the windows example project, that builds without errors.

The build-errors in the error log:
auto-import)

Info: resolving wxAppConsole::ms_appInitFn        by linking to __imp___ZN12wxAppConsole12ms_appInitFnE (auto-import)

C:\Programme\CodeBlocks\MinGW\bin\ld.exe: warning: auto-importing has been activated without --enable-auto-import specified on the command line.

This should work unless it involves constant data structures referencing symbols from auto-imported DLLs.obj\Debug\Windows2Main.o: In function `_ZNK12wxWindowBase10GetMinSizeEv':

Only the linker has some problems.

The System Specs:
WinXP Home SP3
Codeblocks 8.02 with bundled mingw
wxpack for wxWidgets 2.8.8
On Linux Codeblocks 8.02
wxWidgets 2.8.8

P.S. if i forgot relevant info, please excuse me as a newbie.

Thanks in advance for the help

TDragon:
Are you trying to link object files compiled without wxUNICODE #defined with a Unicode build of wxWidgets?

apaeffgen:
Hi TDragon,
i forgot that. Sorry.
The log now says:

Any other hints?
And thanks for the usefull tipp.
Best regards

TDragon:
Actually, I should've said "wxUSE_UNICODE" (note the USE_).

Jenna:
Did you clean the project tree before compiling, or do you use another target for building on win ?

I don't know what happens if you try to link object-files built on linux with the MinGW linker
