How to compile a c++ program into shared library, and load it from a c program?

I am using gnu c compiler on centos 6, and the c program loads the shared library in the code dynamically.

Solution

  • You must declare your function to be useable in C:

    extern "C" void foo(int x, char y);

    Note that you can't do overloading or any of the other features that C++ gives you. (This is because of name mangling.)
