Are you REALLY a maintainer? As a maintainer, it is a given that you know exactly what is in the Leap 15.4 package. As I mentioned earlier, I am talking based on a clean install of Leap 15.4. The Leap 15.4 installer even creates an update repository, which contains a set of gcc12-related files. I didn't know that, and when I began to compile Mesa-22.3.3, etc., I got a message saying to use gcc-12, so I started YaST2, searched for gcc12, and found it, so I just put those in. Now then, you don't understand the meaning of why gcc12 is provided, do you? Anyway, when compiling Mesa and Mesa-drivers, I was told to use libdrm 2.4.110 or higher, even though the system has 2.4.107. I got the src.rpm from the Tumbleweed repo, compiole & install. FYI. I removed libdrm_nouveau2 installed with libdrm, and nvidia blacklisting is no longer necessary. However, vdpauinfo still gives a strange message that libvdpau_nvidia.so is not found, but vainfo works fine. Of course, with the following settings; export LIBVA_DRIVERS_PATH=/usr/lib64/dri export LIBVA_DRIVER_NAME=iHD
