Need new toolchain package with `-mmacosx-version-min=10.9` on OSX

That may actually fix the current issues with the build environment.

Recently, instructions on how to build packages for mac compatible with the defaults channel was changed: https://github.com/ContinuumIO/anaconda-recipes/pull/75/files , FYI. Please go ahead and update the toolchain package. You'll need to update all packages to use the new version of toolchain. I am not sure if you want to release a new package in all packages in the channel though.

A little help would be appreciated!

Do we need to bump build numbers of everything, for example? I'm a bit lost on how to do this cleanly.

That's my question. Do we need to update all packages?

Sincerely speaking, I don't know. So far we have a very intricate issue with what I suspect is an incompatibility with libstdc++ of some sort. I'd like to make sure we remove all evil-eyes out of the way. IMO, at least all C++ stuff should be recompiled.

But doesn't libstdc++ come from the defaults channel rather than the mac system?

What does this mean: -mmacosx-version-min=10.9?

Internet know-how: http://stackoverflow.com/questions/2923502/what-does-macosx-version-min-imply

That's coming from conda-forge. In conda-forge, the compiler is installed on the CI (clang in mac) and it is not shipped. In our channel however, we compile with gcc and libgcc conda pacakges. So I am not sure how would -mmacosx-version-min=10.9 affect us.

If you have any other explanation for what is happening, I'd appreciate other insights. Means to debug the issue would also be helpful. Presently, I think we have an issue with libstdc++. That is my only guess.

Just out of curiosity: how much trouble is it to bump all build numbers after toolchain is reset and rebuild the whole shebang?

You need to do this in the master branch so that it uploads packages as soon as they compile and their tests passes. Also pls disable the artifacts too they are not needed anymore: https://gitlab.idiap.ch/bob/bob.conda/blob/master/.gitlab-ci.yml

Firstly, I'd like to try to completely remove the use of gcc-4.8.5 and libgcc-4.8.5 on the Mac. If we could, we should go 100% native such as anaconda.

This is done.
