Hi @seanyen @j-rivero
This PR adds osx support. The Windows build fails for unrelated reasons; it would be great if you could check why that is.
It would be great if this PR could be merged so we can get Gazebo on osx.

Many thanks!

Hacked the Windows build in 7cc4d49

Seems like Ruby is missing in newer build setups.

It would be great if you could merge this PR :)

@Tobias-Fischer if it's Ruby that's missing, wouldn't it be better to install it with conda?

[wolfv]

ok apparently there is no ruby package for win...

[Tobias-Fischer]

Yeah .. not sure why Ruby was removed from https://github.com/conda-forge/conda-forge-ci-setup-feedstock - ideally we would want to have it back. Let's see whether this hack will allow us to at least merge this for now so we can do further stuff on OSX.

The hack does not seem to work: "Distribution D:\bld\win-64\libsdformat-9.1.0-h7dee32a_3.tar.bz2 is new for conda-forge, but no upload is taking place because the BINSTAR_TOKEN is missing."

Will wait for https://github.com/conda-forge/ruby-feedstock/issues/38 I guess ..

@Tobias-Fischer I think you can skip the Windows build for this release. The Ruby thing looks little more complicated and I anticipated it might take longer runway to tackle it. I don't want this to be a blocker Gazebo on MacOS enablement. :)
