On windows, it does. Notice: ../nmixer/libnmixer.a(nmixer.o): ... undefined reference to ... means that the *library*, libnmixer, has the reference to a missing symbol. That symbol is actually in libncurses, which means that -lncurses must come *after* libnmixer on the link command. Thus... g++ -g -O2 -L../mpegsound -L../nmixer -o nmixer.exe main.o -lnmixer -lncurses -lpthread -lm -lao -lpthread should work (swap -lnmixer and -ncurses) -- Chuck -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
