Conda forge package unavailable for OSX

[rachitnigam]

I tried to install HeteroCL using the instructions here: http://heterocl.csl.cornell.edu/doc/install_from_prebuilt.html#install-with-conda

But ran into this error:

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

PackagesNotFoundError: The following packages are not available from current channels:

  - heterocl

Current channels:

  - https://conda.anaconda.org/cornell-zhang/osx-64
  - https://conda.anaconda.org/cornell-zhang/noarch
  - https://repo.anaconda.com/pkgs/main/osx-64

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

This is presumably because there is no OSX build for the package. Would it be possible to add such a build?

This issue seems to have fell through the cracks.
@hecmay in our installation guide, can we provide a list of operating systems that we can currently support?

We can only provide the conda package for linux-64 and linux-32. The building process targeting OSX can easily fail with conda's built-in g++ compiler and packaging tools.

Users can still build HeteroCL from source on OSX, but packaging it with conda for OSX is hard.

1. HeteroCL cannot be compiled using clang++, which is the default g++ compiler in OSX env.
2. HeteroCL can be compiled if I force the conda to use g++, but Conda would not be able to package the compiled library. The install_name_tool failed with unknown error, and the packaging process exited unexpectedly.

I cannot find a way to do that after trying out all possible solutions I found on the Internet.
