@Yadunund Thanks for raising this issue in ROS.
@wxmerkt Do you know what happens?

[jcarpent]

@Yadunund It seems to work well on #248. Do you know what happens?
It seems Simde is not provided in the build of the ROS package.

The buildfarm environment may be different from the CI environment. You can follow these instructions to reproduce the buildfarm job locally which can help with debugging the issue.

I'm debugging this and I know why it's failing - we have a pending #319 to update our CI and package.xml config here that should also fix it for jazzy. Once merged and a new release has been tagged, I can re-release to the buildfarm to fix the issues.

Iron, Jazzy, and Rolling releases are impacted by lack of availability of simde on RHEL 9: https://pkgs.org/search/?q=simde

Do you know when/if simde may be released for RHEL 9?

I'm not sure but tagging @cottsay in case he knows.

It looks like simde is currently orphaned for EPEL, but is currently built for EPEL 7 and 8. I tested it locally, and the latest version builds successfully in EPEL 9. So it's certainly possible to have the package, but the lack of EPEL maintainer makes it unlikely. I could take up maintenance of the package myself if it is important to ROS 2.

Thank you for the insights. I've now skipped generation on RHEL9 to release for other distros. We can revisit if a need for RHEL9 arises.
