http://bugzilla.opensuse.org/show_bug.cgi?id=1189196 Bug ID: 1189196 Summary: OpenGL: libglfw3 crashes on glewInit(), same code works with libglfw3-wayland Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Development Assignee: screening-team-bugs@suse.de Reporter: rahmspinat@gmx.ch QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:90.0) Gecko/20100101 Firefox/90.0 Build Identifier: Hi, I'm started a project on OpenGl after a long time on openSUSE Tumbleweed. Calling glewInit() throws the error message "glewInit failed: Missing GL version" Searched a lot on stackoverflow etc but no working solutions found. The same program runs on Ubuntu 20.04 without any problem. All other programs using OpenGl (steam, CUDA, ...) are working without any problems. A simple test program and compiling parameter can be found in this issue in RedHat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1895018 Posted this issue on Reddit: https://www.reddit.com/r/openSUSE/comments/p0mca1/opengl_glewinit_throws_err... Due to the answer, I changed to a Plasma-Wayland session, removed "libglfw3" and installed "libglfw3-wayland" and the application worked. I tested it also on a second computer and the result was the same. So I assume X and libglfw3 are not working together anymore, but Wayland and libglfw3-wayland does. Reproducible: Always Steps to Reproduce: 1. In X-Session: Install glfw3 and glew 2. Get OpenGl test code from https://bugzilla.redhat.com/show_bug.cgi?id=1895018 3. Compile and start. Results in crash and error message "glewInit failed: Missing GL version" 4. Deinstall glfw3 and install glfw3-wayland 5. Switch to wayland session 6. Applicarion runs fine Actual Results: OpenGl application crashes and get error message "glewInit failed: Missing GL version" Expected Results: OpenGl application should start. -- You are receiving this mail because: You are on the CC list for the bug.
