Polygeist Undefined reference to `cc1_main` during linking time

Hi,

First of all, super cool work. I watched your presentation at PACT and had to try this project out. But I am running into an issue during compilation.

Error:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
ninja: build stopped: subcommand failed.

When?

While following the Readme instructions for option 1, building llvm and polygeist code with two cmake commands.

System:

I have a build image clang-10, gcc-9, cmake, ninja installed. I used clang-10 to compile llvm without problems, but it fails with the error above during the final linking steps of ninja check-mlir-clang

Questions?

External cc1_main seem to be included from the llvm-project. Maybe there is a library inclusion missing in the mlir-clang's CMakeLists file during polygeist compilation? Or maybe there is something missing in my system.

Have you seen this error before?

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

Also your operating system/etc.

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.

Nov 11 '21 02:11 lcnzg

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.

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.
