Ignition-math6 build failing with LinuxBrew

[varunagrawal]

When trying to install sdformat8 via brew install sdformat8, I get the error Error: osrf/simulation/ignition-math6 6.6.0 did not build.

This does not happen when I build ignition-math from the Github source.

Here is the link to the error log.

Thanks for the report. I've never tried using this tap with LinuxBrew since we support installation through debian packages on Linux. Out of curiosity, what is your reason for using LinuxBrew instead of our debian packages?

It looks like the problem is related to swig, which we added as a build dependency in #1121 to fix #1120. Can you try commenting out the depends_on "ruby" line? If that doesn't work, can you also comment out depends_on "swig"? We could potentially make that dependency OS-dependent

We use brew across Linux and MacOS to manage dependencies better, so it made sense to use brew to install this on Linux as well.

I just tested this, and I can't reproduce the failure. Can you confirm it is still failing? I believe it was caused by the depends on "swig" line that was removed in #1124

Works for me on Ubuntu 20.04, previously I was using 16.04 but I don't think that was the issue. Thanks for the update @scpeters and apologies for the late response. Happy holidays!

I am facing this issue again on Ubuntu 18.04 (as the environment on Github Actions). I'd really like to figure this out properly this time.

Another issue is that I can't even use apt since our application depends on SDFormat8, which isn't available for Ubuntu.
