Thank you for reporting! Have you tried the steps described here.

Yes, tried all of them and the system seems have all the requirement. But the error still occurs.

Unfortunately, I do not have macOS at hand now. Just to be sure, you have exported the following vars, haven't you?

export LDFLAGS="-L/usr/local/opt/libomp/lib"
export CPPFLAGS="-I/usr/local/opt/libomp/include"

I am asking because there have been another related issue recently.

[QinrenK]

Thanks for getting back. Yes, I've exported the vars following the steps shown on another related issue. The error message persists.

[maximtrp]

Could you please post the output of brew info libomp?

==> Dependencies
Build: cmake ✘, lit ✘
==> Caveats
libomp is keg-only, which means it was not symlinked into /opt/homebrew,
because it can override GCC headers and result in broken builds.

For compilers to find libomp you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/libomp/lib"
export CPPFLAGS="-I/opt/homebrew/opt/libomp/include"

[maximtrp]

Please look at this section (the paths are different in your case):

# For compilers to find libomp you may need to set:
export LDFLAGS="-L/opt/homebrew/opt/libomp/lib"
export CPPFLAGS="-I/opt/homebrew/opt/libomp/include"

I hope exporting these vars will fix the error.

Thank you! I have updated the instructions for macOS in README.md.
