当我们在ROCm环境下使用hipcc与OpenMP混编时需注意下列问题：

OpenMP cmake编译问题

当使用rocm-4.0.1/bin/hipcc编译时

使用 Rocm-4.0.1/llvm/include/omp.h
Rocm-4.0.1/llvm/lib/libomp.so来编译

通过

-DCMAKE_CXX_FLAGS=”-fopenmp –I/ Rocm-4.0.1/llvm/include/”
–DopenMP_CXX_FLAGS=” -fopenmp –I/ Rocm-4.0.1/llvm/include/”

-DCMAKE_EXE_LINKER_FLAGS=-L/public/software/compiler/rocm/rocm-4.0.1/llvm/lib
