Poking into the dark: Do the C headers have something like 'extern "C"'
mentioned somewhere?
If not, try
extern "C" {
#include "the_software_C_header.h"
}
A C++ compiler typically "mangles" the function names it enconters, so
the linker might not be able to match them with the symbols from the
library.
