Getting %ldconfig_scriptlets in CentOS 7

[Mikhail Ramendik]

Hello,

A friend of mine is rebuilding an EPEL package (namely llvm9.0) from source
for CentOS 7 on aarch64. The aarch64 build is not in the EPEL repo,
probably because RHEL7 for aarch64 is out of support.

WIth an unmodified .spec file, he gets a message that
the  %ldconfig_scriptlets macro is unknown, or else he gets it built but
not linked and so not running. He had to add "%post -p /sbin/ldconfig" and
rebuild.

I did find the wiki page about this macro at
https://fedoraproject.org/wiki/Changes/Removing_ldconfig_scriptlets but I
could not work out which package should pull this feature into CentOS 7.

So how can he get his aarch64 CentOS 7 to support this macro, to enable
rebuilds without modifying the .spec file?

(Ideally he wants to be able to rebuild for Russian RHEL7 derivatives too).

To clarify, I just realized that he does yum-builddep and then rpmbuild
--rebuild. He does not use mock. But I don't know if this can affect the
issue.

Does the package actually require running ldconfig?

If not, building with "-D ldconfig_scriptlets %{nil}" should work, I
think.

Thanks,
Florian

Yes, it requires running ldconfig.

This says "The %ldconfig_scriptlets macro can be removed on all Fedoras.
Possibly also on
 EPEL 8. But it is required on EPEL 7."

However, on his CentOS 7 the macro *does not work*. What package does he
need to update/rebuild so the macro works?

He needs epel-rpm-macros which provides
/usr/lib/rpm/macros.d/macros.epel-rpm-macros that has the
%ldconfig_scriptlets defined.

I suggest he creates a repo config file pointing to the epel7 aarch64
archives
https://archives.fedoraproject.org/pub/archive/epel/7/aarch64/

That will get him the epel7 packages up to the point that they stopped
being supported.

Thanks a lot!! This resolves the issue.

May I ask you to add this information to
https://fedoraproject.org/wiki/Changes/Removing_ldconfig_scriptlets ? I
tried, but I am having problems with the Fedora Project website; it gives
an Error 500 when I try to complete the FPCA.

IMO , we should add one page on docs (
https://docs.fedoraproject.org/en-US/packaging-guidelines/ )

with what a mention in previous link on this thread ( a page with what
is not necessary anymore) 

I had found a nice wiki page in my bookmarks that have information that
also should be add
https://fedoraproject.org/w/index.php?title=Packaging:Scriptlets&oldi...

https://docs.fedoraproject.org/en-US/packaging-guidelines/ supersede
wiki pages 


we already have
https://docs.fedoraproject.org/en-US/epel/epel-packaging/
