A frequent question.

eu> Adding "extern void foo_test(void);" to the C header files and linking

Close. You must use

    extern "C"

to get proper linkage with C Module. Without "C" the default is "C++".
(Refer page 524 of the C++PL2 from Stroustrup)

The reason for this is that C++ Compilers use different internal names
to distinguish e.g. between overloaded functions of the same name but
different arguments. This is called "name mangling".
