Now I'm trying to use it in Red Hat Linux, [Boggle!] You can't do that. Cygwin is not binary compatible with Linux - it's binary compatible with Windows. You cannot move a cygwin-compiled binary (executable or shared library) to Linux and use it there. You have to either compile it on Linux itself, or specifically compile it with a cross-compiler that creates Linux executables (which won't run on Windows, then). -- Shankar. -- 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/
