Does anyone know how to install Libomp without homebrew?
I do not want to use homebrew on my Mac for some limitations.

@mforotan - I am using https://pkgsrc.org for that. It has binary packages for macOS. However, I prefer installing the packages in ~/.local, so I do the pkgsrc manual builds:

  • download pkgsrc source .tgz of a stable version and uncompress somewhere, eg, ~/pkgsrc or /usr/local/pkgsrc.
  • bootstrap: cd pkgsrc/boostrap && ./bootstrap --unprivileged --prefix PREFIX ... (check the options)
  • environment: add PREFIX/bin, PREFIX/lib to your PATH and DYLD_LIBRARY_PATH respectively
  • now you are ready to build packages: cd pkgsrc/parallel/openmp && bmake install

For binary packages check here: https://pkgsrc.smartos.org
