Linking Visual 2010 to g++

[falcoman33]

Hello,
i have a file toto.lib which is linked by visual2010 (64bits).

I like to use it in QT with g++ (64bits) in my program test.c.

When i link with command
g++ -o test.exe test.o -Lxxx -ltoto.

I have undefined reference.....

can anyone help me to solve my problem?

thanks you

Do you use MinGW?

If the library exports C++ classes and methods I don't think you can link your library compiled with VS 2010 since it has a different binary format then libraries compiled with g++.
