I've tried it but no.

Good point, I've tried and they work. I've seen it uses the option 
-WXUSINGDLL for the compiler. I've tried it and now the errors are like 
this:
/tmp/cc7YZW6G.o(.text+0xdd):app.cpp: referencia a 
`_imp___ZN8wxLocale4InitEii' sin definir
/tmp/cc7YZW6G.o(.text+0xf5):app.cpp: referencia a 
`_imp___ZN8wxLocale10AddCatalogEPKc' sin definir
/tmp/cc7YZW6G.o(.text+0xfc):app.cpp: referencia a 
`_imp___ZN13wxXmlResource3GetEv' sin definir

Now this is the command line:
i586-mingw32msvc-g++ 
-I/usr/local/i586-mingw32msvc/lib/wx/include/msw-2.5-i586-mingw32msvc 
-I/usr/local/i586-mingw32msvc/include -D__WXMSW__ -DWXUSINGDLL -mthreads 
-L/usr/local/i586-mingw32msvc/lib -mthreads 
-Wl,--subsystem,windows,--version-script,./version-script -mwindows 
-lwx_msw_core-2.5-i586-mingw32msvc  -lwx_base-2.5-i586-mingw32msvc   
-lwxtiff-i586-mingw32msvc -lwxjpeg-i586-mingw32msvc 
-lwxpng-i586-mingw32msvc -lwxzlib-i586-mingw32msvc  
-lwxregex-i586-mingw32msvc -lwxexpat-i586-mingw32msvc -mthreads -lrpcrt4 
-loleaut32 -lole32 -luuid -lwinspool -lwinmm -lshell32 -lcomctl32 
-lcomdlg32 -lctl3d32 -ladvapi32 -lwsock32 -lgdi32 -o app.exe app.cpp

I don't know why the samples work, maybe it's because they use the 
compilation directories instead of the installation ones. Maybe the 
problem is the installation I've done with "make install". It's strange 
that I have the libraries and I can see the symbols listed, but the 
linker can't find them. I'm gonna try to compile it like a sample, but I 
can't understand what it's failing.

It uses a script called bk-deps to run the compiler, I don't know what 
it does.

I did it, but it had broken makefiles for the contrib stuff that I need.

My address is blacklisted there, I don't know why.

Thanks and regards.
