Hmm,...
Are you using the precompiled binaries for VisualC++ ?
The downloadable binaries (from savannah) are compiled for VisualC++.
AFAIK, MinGW uses the GNU compilers (gcc). These compilers produce C++
binary incompatible code.

Conclusion:
If you want to link your MinGW compiled app with a C++ library it must
be also compiled with the MinGW compiler.

Indeed :)

You need to recompile ParaGUI with the MinGW compiler.
