Question

I have two precompiled library: X.a and Y.a and a test.cpp (without main function) source code use these two libraries.

I compiled the C++ using:

g++ -c test.cpp

and I got ‘test.o’.

Now how can I link these three together to generate a .a file because test.cpp use some function in X.a and Y.a and other GCC libraries?

BTW, I am doing these under Windows using MinGW. Can I rename this .a file to .lib and use this .lib in VC?

Thanks!

.a is nothing more then ar archive containg all object files (.o files)

Yes, but it requires little trick to work. See:
