In-LLVM-tree build fails: no matching function for call to ‘llvm::StringSwitch<...>::Cases

[eyalroz]

I'm trying to build the translator, checked out today, within the tree of LLVM 21.1.7 (the latest release of LLVM as of today), in tree.

The CMake configure command was:

cmake -G Ninja -S llvm -DLLVM_ENABLE_PROJECTS="clang;lld" \
    -B /path/to/build/dir  -DCMAKE_INSTALL_PREFIX=/path/to/install/dir \
    -DCMAKE_BUILD_TYPE=Release

During the build, I get:

/path/to/llvm-project-21.1.7.src/llvm/tools/SPIRV-LLVM-Translator/lib/SPIRV/SPIRVWriter.cpp:5379:17: error: no matching function for call to ‘llvm::StringSwitch<SPIRV::LLVMToSPIRVBase::FPBuiltinType>::Cases(<brace-enclosed initializer list>, SPIRV::LLVMToSPIRVBase::FPBuiltinType)’

If you're using LLVM 21.1.7, you need to make sure to use the matching SPIRV-LLVM-Translator branch (i.e., llvm_release_210).

I see... I don't suppose there's anything you could do on your side to detect such a mismatch at build configuration time?

For out-of-llvm-tree builds we already do thanks to cmake's find_package. For in-tree builds we would need some custom check I suppose.
