It looks like we can just create `.clangd` config to remove these flags. I.e. ``` CompileFlags: Remove: [-fmodule*, -fdeps-*] ``` And after that everything seems working fine However, I also found that seem we don't forward command mangler right to modules dependency scanner, because I see some errors in logs: ``` E[10:34:07.505] Scanning modules dependencies for .../module-import/Use.cc failed: error: unknown argument: '-fmodules-ts' error: unknown argument: '-fmodule-mapper=CMakeFiles/Use.dir/Use.cc.o.modmap' error: unknown argument: '-fdeps-format=p1689r5' E[10:34:07.506] The command line the scanning tool use is: /usr/bin/g++-14 --driver-mode=g++ -O3 -DNDEBUG -std=gnu++20 -fmodules-ts -fmodule-mapper=CMakeFiles/Use.dir/Use.cc.o.modmap -MD -fdeps-format=p1689r ``` https://github.com/llvm/llvm-project/pull/200001 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
