Can't link wxWidgets app with Code::Blocks / MinGW

Question

I have an already working c++ + wxWidgets app built in Eclipse, with wxWidgets built using MSYS.

Now i'd like to try different IDEs, like CodeLite and Code::Blocks, but when i tried them they did'nt work 'cause i was lacking a build.cfg file they wants. So i tried a "clean" way, backupped the wxWidgets and build them again using MinGW32-make instead of MSYS.

Trying Code:Block now, i get a lot of "undefined reference" errors, and i can't understand what i've done or set wrong.

I'll try to give here all the related info:

Path to wxWidgets:

C:\SVILUPPO\TOOLS\wxWidgets

Path variable (the related part)

PATH=C:\SVILUPPO\TOOLS\MinGW\bin;C:\SVILUPPO\TOOLS\MinGW\libexec\gcc\mingw32\4.8.1;

Mingw v4.8.1, make version

C:\SVILUPPO\TOOLS\wxWidgets>mingw32-make -v
GNU Make 3.82.90
Built for i686-pc-mingw32

wxWidgets build command:

C:\SVILUPPO\TOOLS\wxWidgets\build\msw>mingw32-make -f makefile.gcc BUILD=debug UNICODE=1 SHARED=0 MONOLITHIC=1

Code::Block build log:

19 error(s), 2 warning(s) (0 minute(s), 29 second(s))

I also tried adding other libs i had to add when i built this code under arm-linux) in the linker settings, but these libraries files are not existing (i guess 'cause the MONOLITHIC option):

libwxmsw30ud_core.a
libwxmsw30ud_html.a
libwxmsw30ud_adv.a
libwxbase30ud_xml.a
libwxmsw30ud_richtext.a

In the end, i don't know what i should to finally link and debug my sources from Code::Block.

您需要链接在构建wxWidgets时创建的libwxexpat.a 。
