This has proved problematic in our stack especially as was seen with `numpy` ( https://github.com/conda-forge/numpy-feedstock/issues/15 ). However, unlike with `openblas` we cannot simply just ship `libgfortran` as `scipy` has C++ code and thus depends on `libstdc++`. Given the shipping of `libstdc++` was the cause of the issues with code depending on `numpy`, it is tricky to find an easy fix here.\r\n\r\nThere are two main options to avoid shipping `libstdc++`. First, try to use `gfortran` and `libgfortran` from the `gcc` package only and otherwise use the image compilers and libraries. Second, try to use system compilers for the whole process, but have everything link to our `libgfortran` instead. Attempts to get the first point to work with `openblas` proved tricky and we were unable to get it to work. So, we are skipping that option and going for the second one instead. Hopefully we can evaluate the effectiveness of this strategy and move forward from there."},"comment":{"url":"https://api.github.com/repos/conda-forge/scipy-feedstock/issues/comments/231887271","html_url":"https://github.com/conda-forge/scipy-feedstock/pull/3#issuecomment-231887271","issue_url":"https://api.github.com/repos/conda-forge/scipy-feedstock/issues/3","id":231887271,"user":{"login":"pelson","id":810663,"avatar_url":"https://avatars.githubusercontent.com/u/810663?v=3","gravatar_id":"","url":"https://api.github.com/users/pelson","html_url":"https://github.com/pelson","followers_url":"https://api.github.com/users/pelson/followers","following_url":"https://api.github.com/users/pelson/following{/other_user}","gists_url":"https://api.github.com/users/pelson/gists{/gist_id}","starred_url":"https://api.github.com/users/pelson/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/pelson/subscriptions","organizations_url":"https://api.github.com/users/pelson/orgs","repos_url":"https://api.github.com/users/pelson/repos","events_url":"https://api.github.com/users/pelson/events{/privacy}","received_events_url":"https://api.github.com/users/pelson/received_events","type":"User","site_admin":false},"created_at":"2016-07-11T22:40:38Z","updated_at":"2016-07-11T22:40:38Z","body":"This looks pretty good to me. 👍 "}}
