He was responding to your question about "why am i getting this warning". Your command line looked like this: > /bin/gcc -c -g -mno-cygwin -I. -I../../include -I/usr/include/mingw -I/usr/include >-DCYGWIN mksf.c > ^^^^^^^^^^^^ >So mine was more of a question: If as Peter says /usr/include is the 3rd >library searched, why isn't getopt.h being found? In the example that you specified there was no hint that it wasn't found. In fact, you said "this works" (sic). You were asking about a warning. >(Another side question would be why is /usr/include/mingw listed >twice?). You specified -I/usr/include/mingw on the command line and it is already included by default when you use -mno-cygwin. Let me say it again. If you want to compile a windows-only app, you just use -mno-cygwin. If you find that some function is missing when you do this, that means that the function is likely missing from the mingw distribution. The solution in this case is not to link in the bits that you need from cygwin directories. -mno-cygwin is supposed to be a world by itself. You usually can't mix it with cygwin bits and get anything useful. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
