how to solve this problem

[victorygogogo]

if use "DLLVM_INSTALL_UTILS=ON" will cause this problem.

The issue seems like mixing gcc with the lld linker. Which version of gcc are you using? (/usr/bin/cc --version)
Disabling -DLLVM_ENABLE_LLD=ON or building with clang (or a more recent gcc) should work I think?

[victorygogogo]

gcc version (Ubuntu 8.4.0-1ubuntu1~18.04) 8.4.0 ,
Disabling -DLLVM_ENABLE_LLD=ON build is ok when use "build_tools/build_mlir.sh ${PWD}/llvm-project/ ${PWD}/llvm-build" this command
$ mkdir build && cd build
$ cmake .. -GNinja
-DLLVM_ENABLE_LLD=ON
-DCMAKE_BUILD_TYPE=Release
-DLLVM_ENABLE_ASSERTIONS=On
-DMLIR_DIR=${PWD}/../llvm-build/lib/cmake/mlir
$ ninja check-mlir-hlo
use the above command, set -DLLVM_ENABLE_LLD=OFF \ cause a link problem , so set -DLLVM_ENABLE_LLD=ON build is ok, is there any problem build like this?

and how to build wth clang ,can you tell me ?
