Undefined reference to `cc1_main` during linking time about polygeist

[wsmoses]

Interesting, do you mind pasting the output of your cmake (on a new build).

Also your operating system/etc.

[agostini01]

For sure. Here are the outputs after removing and re-creating polygeist build folder and executing the readme commands:

cmake -G Ninja ..   -DMLIR_DIR=$PWD/../llvm-project/build/lib/cmake/mlir   -DCLANG_DIR=$PWD/../llvm-project/build/lib/cmake/clang   -DLLVM_TARGETS_TO_BUILD="host"   -DLLVM_ENABLE_ASSERTIONS=ON   -DCMAKE_BUILD_TYPE=DEBUG

Same error here.

Building Polygeist as an external project (Option 2) worked.

[mmoadeli]

I bumped into the same issue when I tried to build Polygeist using DPC++ to have Polygeist support SYCL input. I managed to fix the issue by building clang in llvm-project/build folder and building mlir in llvm-project/build-mlir folder and using those paths for clang and mlir when building Polygeist.

[mgehre-amd]

When I removed the option -Wl,-rpath-link, (i.e. with an empty path) from the linker command line and manually rerun the command, it linked correctly. But I didn't spent time to figure out where to fix this in cmake.
Setting LLVM_LIBRARY_OUTPUT_INTDIR in the CMakeLists.txt fixes this issue.
