Hi Michael, Thanks for the build check and compile error messages. Actually, I also did the compile check locally and through pre-patch system. We do shared libs compile with gcc and latest libva and msdk master deps, and it passes the check. It seems this error occurs with clang. Could you provide some details on how to reproduce it? (e.g. compiler, distro, deps, flags, etc.). Thus we can add into the system to refine the pre-patch check and have this clang compile issue fixed?
