After doing some web searches for <complex.h> and Cygwin, I found there doesn't seem to be any support unless I use: gcc -I/usr/include/mingw -lm tc.c But I still end up with:
/cygdrive/c/DOCUME~1/JOHNC~1.ECS/LOCALS~1/Temp/ccAPGnIv.o:tc.c:(.text+0x3d): undefined reference to `_ccos' collect2: ld returned 1 exit status I'm really not interested in working with MinGW either. All the messages about <complex.h> and Cygwin are rather old (<2007) so I was hoping that 1.7 would remedy the problem. Evidently not? ---John -- 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
