Title: MinGW32-GCC linker problem: lots of "undefined reference to" errors
Post by: Comp_Lex on November 14, 2007, 09:44:36 pm

Hello,

I have a problem with linking all the object files of my project in Codeblocks using wxWidgets 2.8.6 unicode static lib. Something has to do with the position of the links to static libs, dynamic libs an object files on the command line for mingw32-gcc, but I can't seem to fix it. I've looked at other topics on this forum and found some that look like my problem, but they're not really it. I hope you can fix it :)

My build log:

mingw32-g++.exe -LC:\wxWidgets-2.8.6\include

You need to fix this it should be a path to the Library.

I would guess it should be "mingw32-g++.exe -LC:\wxWidgets-2.8.6\lib\gcc_lib"

What compiler are you trying to use? MinGW GCC or Microsoft Visual C++?
( The log above showing includes of Microsoft Visual C++ folders which will cause issues.)
