Yes it is okay to link such libraries. However if a C function is
being used in a C++ program, The linkage directive
extern "C" (function name)
must be given in C++ program. The default linkage is extern "C++".

Is it OK to make a library using C compiler and link it with C++
compiled object files or vice versa?

If not, how do the standard libraries like the math library work ?

Thanks.

If the two compilers are from the same supplier, then it should be ok to
use libraries from both C and C++ compiler in the same project. The
C++ language supports this by the 'extern "C" <prototype>'-construct, i.e.
all routines shares between C and C++ must be defined in the C++ program
using it. But IMHO at least the ARM doesn't require a C++ implementation to be
object-code compatible with C-implementations, although it's recommended, and
All C++-compilers I've seen have supported it.
