Hello, I recently updated my Linux to glibc-3.2.2 . With the new errno implementation, errno.h is no longer automatically included. Thus one needs to #include <errno.h> in gx11.c for the gtk-client. As it does already for the cygwin environment. That's all. Server + client are running fine. :-) Bernd Edler _______________________________________________ crossfire-devel mailing list crossfire-devel at lists.real-time.com https://mailman.real-time.com/mailman/listinfo/crossfire-devel
