我一直在尝试使用 clang 构建一个使用 openMP 的库,但出现此错误:

In file included from cafxlibrary.cpp:2:
In file included from /opt/homebrew/Cellar/eigen/3.3.9/include/eigen3/Eigen/Dense:1:
/opt/homebrew/Cellar/eigen/3.3.9/include/eigen3/Eigen/Core:266:10: fatal error: 'omp.h' file not found
#include <omp.h>
         ^~~~~~~
1 error generated.

即使我在 /opt/homebrew/Cellar/libomp/11.0.1/include/ 中有 omp.h。我已尝试将环境变量 CPLUS_INCLUDE_PATH 设置为指向 /opt/homebrew/Cellar/libomp/11.0.1/include/,但出现此错误:

ld: library not found for -lomp
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我使用的命令是:

clang++ -dynamiclib -DNDEBUG -I/opt/homebrew/Cellar/eigen/3.3.9/include/eigen3/ -Xpreprocessor -fopenmp -o libcafx.dylib cafxlibrary.cpp -lomp -std=c++11

我也试过不使用 -lomp。我还使用自制软件安装了 llvmlibomp,但问题仍然存在。我也试过将 omp.h 直接放在 /opt/homebrew/Cellar/eigen/3.3.9/include/eigen3/Eigen/src/Core 中。任何帮助表示赞赏。
