A might-be-sloppy resolution I came out is to use boost to transform
SOURCE_DIR macro to string, which is
#include <boost/preprocessor/stringize.hpp>
...
void test ()
{
...
std::string string_from_macro = BOOST_PP_STRINGIZE(SOURCE_DIR);
...
}
It worked, but as what I said, in a sloppy way. I'd be happy to see what
you guys have in mind.
