Unrelated, but in C++ you should use <cstdio> and <cctype> instead of the .h files. > Now trying to compile gives: > chrisd$ g++ -std=c++11 -o test test.cpp > Undefined symbols for architecture x86_64: > "isalnum(int)", referenced from: > _main in ccDuU6gp.o > ld: symbol(s) not found for architecture x86_64 > collect2: error: ld returned 1 exit status There is a problem with the header files shipped with OS X. This is tracked in this ticket: http://trac.macports.org/ticket/41033 The problem only exists with the combination of g++-mp-4.* and -std=c++11, compiling earlier C++ code using g++-mp-4.* should work. The best known workaround is to use clang++ instead of g++ for C++11 code.
