C++ wxWidgets Code::Blocks cross-compiling linking

I use Lubuntu 14.04 LTS AMD64.
In this way I compiled wxWidgets 3.0.1 with the help of that tutorial (I changed global compiler settings, not the target ones - my target to Win name is Windows ):

/home/tomasz/Pobrane/src/wxWidgets-3.0.1/configure prefix=/usr/local/i386-mingw32 --host=i386-mingw32 --build=x86_64-linux --enable-unicode --disable-shared --disable-debug --with-msw --enable-stl

Then i used make -j3 and install make. Everything - OK. However, there is the problem with linking:

obj/Windows/main.o:main.cpp:(.text+0x23): undefined reference to `wxEntry(HINSTANCE__*, HINSTANCE__*, char*, int)'
obj/Windows/main.o:main.cpp:(.text+0x81): undefined reference to wxAppConsoleBase::CheckBuildOptions(char const*, char const*)'

I think that the problem is connected with wx/app.h because when I disabled it, there weren't errors like the ones.

The whole log:

There are two completely separate problems here:

The link errors are just due to not linking with wxWidgets libraries at all -- your command line doesn't mention them anywhere. Use the output of wx-config --libs in your makefile.
The C++11 compilation problems are due to compiling wxWidgets without C++11 support. With g++ you can't use C++11 in your application without using it in the library or vice versa as C++98 and C++11 are not ABI-compatible. Rebuild the library with CXXFLAGS=-std=c++11 to fix this.
