Hello, I've just upgraded from w32api-2.4 to -2.5. It looks like <GL/glu.h> file included in 2.5 is missing a definition of GLU_ERROR. In w32api-2.4, GLU_ERROR is defined on line 76, and a commented out version on line 177 (for completeness I suppose). In w32api-2.5, the first definition has been removed, and the second you can still see commented out on line 123 of glu.h. Suggested fix: amend line 123 of <GL/glu.h> in w32api package to read: #define GLU_ERROR 100103 This bug breaks all sorts of existing code. -- Philip Lamb phil@rave.co.nz -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
