Hi Hossein, *; after looking at a log of another user having issues, I noticed another anomaly...

For the other user on VS 2022 that likely means the necessary clang components were not installed, but in your case it finds clang.exe > > checking the dependency generation prefix (clang.exe -showIncludes)... and clang-cl.exe should be in the same folder as clang.exe - so that's strange. It would also be strange if VS would change their component structure in-between releases without noting it on their release notes, but in any case please double-check that you have clang-cl installed as part of Visual Studio. clang-cl.exe is the compatibility layer that makes clang understand the MSVC-style switches, so if called with just clang the -showIncludes probably just fails because of an unknown command line option.. In the original mail you write clang-cl would be available in a developer prompt, so please determine the locations where it is installed to in the 18.7.0 version. configure.ac assumes them to be in $VC_PRODUCT_DIR/Tools/Llvm/bin - but maybe that switched to a versioned directory... ciao Christian
