参考本文 stackoverflow，成功在MacOS编译LightGBM

1. 安装两个依赖

brew install llvm arch -x86_64 brew install libomp 

2. 在CMakeLists.txt加上这些代码

message(STATUS "set env var") set(ENV{ 
        CC} "/usr/local/opt/llvm/bin/clang") set(ENV{ 
        CXX} "/usr/local/opt/llvm/bin/clang ") set(ENV{ 
        LDFLAGS} "-L/usr/local/opt/llvm/lib") set(ENV{ 
        CPPFLAGS} "-I/usr/local/opt/llvm/include") message(STATUS "set compipler") set(CMAKE_C_COMPILER "/usr/local/Cellar/llvm/5.0.1/bin/clang") set(CMAKE_CXX_COMPILER "/usr/local/Cellar/llvm/5.0.1/bin/clang ") set(OPENMP_LIBRARIES "/usr/local/Cellar/llvm/5.0.1/lib") set(OPENMP_INCLUDES "/usr/local/Cellar/llvm/5.0.1/include") 

3. 将CMakeLists.txt 的 O3 改为 O0

4. 取消openmp并行

全局替换，将#pragma omp parallel for 替换为 //#pragma omp parallel for

5. 配置CLion的run configuration

点击运行，结果符合预期
