Created attachment 643098 [details, diff] fix undeclared identifier in kwin-5.18+ My system is mostly compiled using clang, the clang runtime compiler-rt, llvm's libc++ and the llvm toolchain. I haven't tested this using gcc so I don't know if gcc catches the same error. kwin will fail the compile phase when trying to compile clockskewnotifierengine_linux.cpp which is new from the kwin-5.17 to kwin-5.18 brach. The issue is an undeclared identifier. I'm attaching a patch which declares the identifier so kwin can compile proper under clang + the llvm toolchain.

Created attachment 643100 [details] pre-patch failure and post-patch success build logs
Please submit your patch upstream.
Before that though, please make sure your user patch is not the problem here. > * Applying kwin-lowlatency-5.18.5.patch ... > [ ok ]
I'm 99% sure I tested it on vanilla without the low-latency patch but I just double checked and the failure still happens without. How do I upstream the patch?
