Sorry I was not very clear about how to reproduce. Here is the easiest way to reproduce the error with docker
using the latest gcc
image:
$ docker run -it gcc:latest bash
// the commands below run inside the container
$ git clone https://github.com/llvm/clangir/ --depth 1
$ apt update && apt install cmake ninja-build -y
$ cd clangir
$ mkdir build
$ cmake ../llvm -GNinja -DLLVM_TARGETS_TO_BUILD="host" -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_PROJECTS="clang;mlir;cir" -DCMAKE_BUILD_TYPE=Debug
$ ninja clang
I have tried it on different Linux machines (I doubt it matters but just in case), and they all have the same linker error. Note that if I use Release
mode, the code compiles fine.

Hi @Kuree, thanks for reporting this, I think I know what's happening here, should have a fix later today.

Do you have more info? I think undefined reference would be a linker error so doesn't seem related to the compiler. I just did clean builds on both Darwin and Linux and both passed check-clang-cir
.
Maybe try a clean build? We've had issues with stale td generated files over time, could just be another instance of that .
