Am using llvm-10.0.0.src and clang-10.0.0.src, on Windows 10 x86-64, Visual Studio Community 2019 Version 16.6.0 . After moving the clang source to tools/clang in the LLVM source, and setting up with cmake:
cmake -Thost=x64 ..\llvm-10.0.0.src
I load llvm-libraries.vcxproj into VS, and the build fails. Here is an excerpt from the log file:
Building Attributes.inc... llvm-tblgen.exe: Unknown command line argument '-gen-attrs'. Try: '..\..\..\Debug\bin\llvm-tblgen.exe --help'
I run llvm-tblgen, as suggested, and get:
>.\llvm-tblgen.exe --help llvm-tblgen.exe: Unknown command line argument '--help'. Try: '.\llvm-tblgen.exe --help' llvm-tblgen.exe: Did you mean '--color'?
I have full log files – Normal and Detailed, but don’t see how to attach them. A few months ago I was able to compile the version 10 code fine, although it was with a slightly older version of VS.
