The error occurs when it encounters a plot statement. I have had this problem with an old installation of cygwin for at least a year. I finally decided to wipe out cygwin and try a fresh installation. This installation contains the "minimal" default packages plus Devel: gcc-core, gcc-gfortran, gcc-g++, gdb, mingw64-x86_64-gcc-core, mingw64-x86_64-gfortran, mingw64-x86_64-g++; Graphics: gnuplot, ImageMagick; Math: bc, grace, octave; Shells: tcsh; X11: everything. I notice that libGLEW is included in the packages that it installs, which is where I would expect to find the WGL extensions. This contains /usr/bin/cygGLEW-2-1.dll, but I don't know how to find out what functions are in a dll to see if it contains WGL_ARB_multisample. Any suggestions on what is wrong with this installation are greatly appreciated. -- 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
