Upgrade CI to newer os version

[SeanCurtis-TRI]

macos-11 is no longer supported by github.
ubuntu 20 is likewise ridiculously old.

This includes benign changes to make the mac compiler happy.

[SeanCurtis-TRI]

Thanks! I'm sorry I missed your earlier PR.

[SeanCurtis-TRI]

I've exhausted my best efforts at making the mac build happy. Unless someone else can contribute more than I can, I'm going to replace this PR with one that simply no longer tries to test against mac.

Which configuration are interested in testing? Downstream we are already packaging fcl on mac in conda-forge (https://github.com/conda-forge/fcl-feedstock), so it is trivial for us to contribute a mac ci based on conda-forge dependencies as opposed to brew one, see traversaro#1 for an example. In there the compilation works fine, while there are three tests that fail on macOS (from the log at https://github.com/traversaro/fcl/actions/runs/13830174941/job/38692485376?pr=1):

99% tests passed, 3 tests failed out of 274

Total Test time (real) = 120.79 sec

The following tests FAILED:
	 41 - CapsuleCapsuleSegmentTest.OverlappingCenterLines<double> (Failed)
	 42 - CapsuleCapsuleSegmentTest.NominalSeparatedCase<float> (Failed)
	233 - FCL_GJK_EPA.ComputeVisiblePatchColinearNewVertex (Failed)
Errors while running CTest

all tests are passing fine on macOS.

No problem if you not interesting in having this in the CI as actually you are interested in mac with dependencies provided by brew, not dependencies provided by another package manager.

[SeanCurtis-TRI]

In this case, the failing dependencies aren't coming through brew, they're coming from the CI pre-building a specific version of octomap.

However, I'm incredibly mac ignorant and would welcome any help you might be able to offer. :)

In this case, the failing dependencies aren't coming through brew, they're coming from the CI pre-building a specific version of octomap.

I think octomap was built from source as back in february 2018 homebrew science (that contained octomap) was deprecated, and octomap was not migrated to core, see #262 . However, in March 2018 octomap was added back in homebrew (see Homebrew/homebrew-core#24528) and it is still available there: https://formulae.brew.sh/formula/octomap . I may be missing something, but there is any reason for which we can't simply brew install octomap instead of compiling from source in https://github.com/flexible-collision-library/fcl/blob/master/ci/install_osx.sh#L8-L16 ?

[SeanCurtis-TRI]

Currently, fcl is pinned to an older version of octomap.

This is generally bad because it also limits this CI workflow working on newer Linux CI as well (the pinned octomap version simply isn't ready for modern compilers).

So, generally, it would be good to modernize the octomap. I haven't looked into what that would take. I don't know how things have changed in the 9 years between the pinned version and the current version. But, evaluating that is probably the first step.

I did a quick check in https://github.com/flexible-collision-library/fcl/actions/runs/13901821176/job/38895257356, and it seems that compilation wise everything works fine, while for testing 4 tests are failing:

99% tests passed, 4 tests failed out of 277

Total Test time (real) =  55.34 sec

The following tests FAILED:
	 41 - CapsuleCapsuleSegmentTest.OverlappingCenterLines<double> (Failed)
	 42 - CapsuleCapsuleSegmentTest.NominalSeparatedCase<float> (Failed)
Errors while running CTest
	 90 - FCL_GEOMETRIC_SHAPES.shapeDistance_conecylinder (Failed)
	233 - FCL_GJK_EPA.ComputeVisiblePatchColinearNewVertex (Failed)

however, at the first glance the failures are not octomap related.

[SeanCurtis-TRI]

That's good to know. Can you do me a favor and push to this PR the change to modernize octomap and I can look at the tests.

The test failures are somewhat surprising; they shouldn't have anything to do with octomap....hmmm....

I am probably missing something, but what do you mean with "push to this PR"? I can't push on your fork.

[SeanCurtis-TRI]

You can. :) You have several options:

1. Use the github API to edit the branch directly (tedious for all but the simplest of changes).
2. Check out my actual branch, add a commit, and push it back to my repo.
3. Alternatively, if you share with me your branch, I'll just cherry pick the changes necessary to reproduce the problem.

I'm good with any of the above.

Sorry, I feel really I am missing something.
