After successfully compiling mlir-hello on Ubuntu 18.04.4 LTS (with Linux kernel 4.15.0-101-generix x86_64) with the following configurations:
(using the llvm version in the update-llvm-2023-08-24 branch)
source ~/.unset ; $CMAKE ../llvm/ -G Ninja -DLLVM_ENABLE_PROJECTS="clang;polly;mlir;lld;openmp;lldb" -DCMAKE_INSTALL_PREFIX=/mnt/heorot-10/Installs/LLVM18/release/ -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_RTTI=ON -DLLVM_BUILD_EXAMPLES=ON -DLLVM_TARGETS_TO_BUILD="Native;NVPTX;AMDGPU" -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_INSTALL_UTILS=ON
Then I installed this LLVM build and set the environment to use it:
export LLVM_ROOT=${INSTALLS_HOME}LLVM18/release/
export CC=${LLVM_ROOT}bin/clang
export CXX=${LLVM_ROOT}bin/clang++
export LLD=${LLVM_ROOT}bin/ld.lld
When running build/bin/hello-opt on test/Hello/hello_world.mlir (and print.mlir) I get a segmentation fault.
Running with lldb, I get the following output:
$LLVM_ROOT/bin/lldb ./build/bin/hello-opt test/Hellow/hello_world.mlir(lldb) target create "./build/bin/hello-opt"
Current executable set to '/mnt/heorot-10/Builds/mlir-hello/build/bin/hello-opt' (x86_64).
