However, if I write a C++ program that calls domp_malloc, and try to build it with my special g++, the linker cannot find the definition of domp_malloc, so my build fails. What else can I do to make domp_malloc visible to the C++ linker? You shouldn't need to do anything. What's the linker error? How are you declaring domp_malloc in the C++ program? Is it a name-mangling issue, such that the C++ program is looking for extern "C++" void* domp_malloc(size_t) but the library defines extern "C" void* malloc?
