[Python-modules-team] Bug#960073: Package:python-pyqt5 Run the example code with Trace and crash (SIGABRT) 【请注意，邮件由mity...@gmail.com代发】
Hi! Sorry for my late reply. I preload libGLX_mesa.so.0 , and then run the code on the arm machine is ok. I tried to debug it, and then I found something different. The parameter of __glXLookupVendorByName is NVIDIA instead of mesa, it will dlopen libGLX_nvidia.so.0, but my Graphics Card is AMD, only IibGLX_mesa.so.0 can be found locally, so __glXLookupVendorByName failed. (gdb) b libglxmapping.c:574 Breakpoint 4 at 0xf3a993d0: file ../../../src/GLX/libglxmapping.c, line 574. (gdb) r [...] Thread 1 "python" hit Breakpoint 4, __glXLookupVendorByScreen (dpy=dpy@entry=0xab1f8de0, screen=screen@entry=0) at ../../../src/GLX/libglxmapping.c:574 (gdb) p name $11 = 0xe0006330 "nvidia" (gdb) b libglxmapping.c:430 Breakpoint 5 at 0xf3a97f74: file ../../../src/GLX/libglxmapping.c, line 430.

If you could please shed some light on this topic, I would really appreciate it. Thank you in advance.

Hi! Some information on this, it look like the same issue as #963709.

Hi! I add this code on top of the python file and it works now. I read this https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=963709#39 , but I don’t understand why this is effective. Thank you very much for your help .

Hi! I tried to verify the local opengl/glx, they are normal. It is no problem to write QT code directly to call qtwebengine. So I suspect that the problem is caused by pyqt. Looking forward to hearing from you soon. Thanks.

Hi! Sorry for my late reply. I tried to exporting QT_XCB_GL_INTEGRATION=xcb_egl and it still reported an error. libglvnd-dev package was originally installed. Do you need other information? Thank you in advance. BRs //Zongli ___ Python-modules-team mailing list Python-modules-team@alioth-lists.debian.net https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/python-modules-team
