I include a makefile to compile a C++ written module. In addition:
1) init_module() and cleanup_module() have to be prefixed with
extern "C" to avoid name mangling problems.
2) All kernel includes and declarations have to be bracketed with
#ifdef __cplusplus
extern "C" {
#endif
#include <kernel_stuff>
#ifdef __cplusplus
}
#endif
It works fine here using gcc 2.8.1 - I have not tried any other
compiler.
