I just installed MacPorts, and gcc49, and tried to compile a simple
program, which really should work, but I'm getting a link error. I
narrowed it down, and if I take out the use of any regex then it will
link. I can leave in the #include <regex> line, but if I have any line
that actually does a regex_search or a regex_replace, then I get the
following error output when I compile and link (with my compile line
shown first):
g++-mp-4.9 -std=c++11 -ggdb test-program.cxx -o test-program
Undefined symbols for architecture x86_64:
"__istype(int, unsigned long)", referenced from:
std::ctype<char>::is(unsigned long, char) const in test-program.o
ld: symbol(s) not found for architecture x86_64
collect2: error: ld returned 1 exit status
Can anyone help me? I don't know what to do next.
Regards,
Geoffrey Odhner
