AW: BUG #16858: clang10-devel packages are missing in SLES15 SP2 in general

Hello Devrim,

we have just synchronized and updated our Repositories of PostgreSQL 11, 12 and 13 for SLES15 SP2 from PostgreSQL download sites.
But we still have the issue about missind clang10-devel when installing PostgreSQL development version 11 or 12.
Installatin of version 13 is working. Is there a Repository where we can get clang10-devel from?
Can you advice how to proceed with this problem, please

Many thanks
Kind regards
Heiko

Hi,

we have just incuded repositories of PostgreSQL 11, 12 and 13 for
SLES15 SP2 to our SUSE Manager environment from the following download links:

https://download.postgresql.org/pub/repos/zypp/12/suse/sles-15.2-x86_64/
https://download.postgresql.org/pub/repos/zypp/13/suse/sles-15.2-x86_64/

When trying to install the development package for PostgreSQL version
11 or 12 there is a dependency to clang10-devel package that doesn't seem to be a part of SLES15 SP2.
As far as we know, clang9 and clang9-devel versions are included from SUSE for SLES15 SP2.
But installing of PostgreSQL version 13 is possbile, so maybe this version is bound to clang9?

I'm using the following repo repo for LLVM and CLANG:

zypper addrepo https://download.opensuse.org/repositories/home:aaronpuchert:Backports:SLE-15/openSUSE_Backports_SLE-15-SP1/home:aaronpuchert:Backports:SLE-15.repo

but looks like they also removed clang 10, and added 11. Let me see what I can do. I think downgrading to 9 is not an option for now. Looks like I will need to upgrade to clang 11, and rebuilt the packages with that .

FWIW, I (try to) document the external SLES 15 repos that I use for building and installing PostgreSQL and related RPMs on this platform:
