[BUG] - CppSharp cannot process files with latest MSVC (14.44.35207) STL

[smaillet]

Using CppSharp to parse C++ files fails on Windows for MSVC (14.44.35207) with the following error:

C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\MSVC\14.44.35207\include\yvals_core.h(908,1): ERROR: static assertion failed: error STL1000: Unexpected compiler version, expected Clang 19.0.0 or newer.

Apparently, the version of clang used in the library is old and no longer supported by the MSVC version of the STL

[ArthurGW]

Can confirm, MS STL installed with Visual Studio 17.13 onwards isn't compatible with Clang < 19.

Raising the error was added in this commit: microsoft/STL@0190042#diff-bdd45474f9376628362c583aa24d827009c50f6c19e3148b225937224338a444R933

No idea how much work it is to update CppSharp to use Clang 19 (or 20). I tried pinning LLVM to this commit: llvm/llvm-project@cd70802

then running

• build.sh clone_llvm
• build.sh build_llvm
• build.sh package_llvm

but the built package had a slightly different layout to the one downloaded from here (missing the lib folder).
