linux - Using C++ classes in .so libraries -

-

i'm trying write small class library c++ course.

i wondering if possible define set of classes in shared object , using them directly in main program demos library. there tricks involved? remember reading long ago (before started programming) c++ classes worked mfc .dlls , not plain ones, that's windows side.

c++ classes work fine in .so shared libraries (they work in non-mfc dlls on windows, that's not question). it's easier windows, because don't have explicitly export symbols libraries.

this document answer of questions: http://people.redhat.com/drepper/dsohowto.pdf

the main things remember use -fpic option when compiling, , -shared option when linking. can find plenty of examples on net.
