MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit References: <2026486348 DOT 2432030 DOT 1464050301698 DOT JavaMail DOT yahoo DOT ref AT mail DOT yahoo DOT com> Have there been any changes to OpenGL libraries in 32-bit cygwin in the last six months? The opengl application I use (geomview 1.9.5) is now crashing on an uptodate Cygwin where it worked previously. (Can't compare with previous Cygwin install - had to replace drive) It runs without texturemapping when opengl is not used (geomview -noopengl -run savi), suggesting problem is with opengl. Building with -g and using gdb to backtrace shows nothing helpful, suggesting problem is with opengl libraries? To duplicate crashing: http://www.geomview.org/download cd geomview-1.9.5 ./configure --enable-d1debug (to build with -g throughout) make (ignore any pdf build errors after binary is built; that's just TeX for you. lots of gcc -DHAVE_CONFIG_H -I. -I../../../.. -I../../../../include -g -MT stack.o -MD -MP -MF .deps/stack.Tpo -c -o stack.o stack.c etc. ) cd .. http://savi.sf.net/ cd savi1.4.9 make ARCH=cygwin ../geomview-1.9.5/geomview -gdb -run ./savi thanks Lloyd Wood http://savi.sf.net/ ~/savi/savi-dev $ ../geomview-1.9.5/geomview -gdb GNU gdb (GDB) (Cygwin 7.10.1-1) 7.10.1 Copyright (C) 2015 Free Software Foundation, Inc.
