Unfortunately, we have discovered a problem with building the 22.0.0 release from source (e.g. with newinstall.sh) on macOS. This problem does not occur on our CentOS 7 reference platform or with other Linux distributions.

As a workaround, you can run newinstall.sh as follows:

$ export LSST_SPLENV_REF=v22_0_0_rc1
$ bash newinstall.sh

which will allow proper source building.

We are anticipating issuing a 22.0.1 release to fix this problem.

Thanks for the news. I have successfully run though the pipeline with V21 and now plan to repeat the process with V22.

Science Pipelines Release 22.0.1 is now available. This release incorporates patches to the sconsUtils package to allow it to be used with recent versions of the conda compilers on macOS. There are no other code changes, and the documentation in pipelines.lsst.io for Release 22.0.0 remains valid.

Note that rubin-env version 0.4.3 is to be used with this release, and that a new build of this environment is available that better guarantees compatibility with the Science Pipelines source. If you have previous newinstall or lsstsw environments, you may want to re-create or update them.
