Note one important step will be to make sure (at least for the shared libraries) that no symbols are removed. Ideally that should be the case for the static libraries as well - we've had multiple issues here in the past with lapack deprecating APIs and not building them by default when not specially asked.

That might be OK for openSUSE but for old SLES codestreams we have to be careful. I'm not sure for SLE15 -> SLE16 compatibility but breaking the shared library ABI would be bad.

Could you suggest what SLE versions I should test the update against? I see that OBS allows me to add SLE-11-SP4, SLE-12-SP5, and SLE-15-SP1 through SP6 as build repositories to the project.

I think the best is to check SLE15 SP6 or simply what's in Leap 15.5 or 15.6 (I suppose we don't have any newer version in Backports). Note that on SLE15 lapack is built against the SLE-15:Update tree (thus against GA), but this shouldn't make a difference with respect to the ABI. -- You are receiving this mail because: You are on the CC list for the bug.
