Parametric macro dependency generators are not supported in EPEL 7 and
8's RPM versions. You can still implement this using a "regular"
dependency generator. This is also described in the RPM
documentation[1]. Instead of specifying %__perlcompat_requires() and
writing an RPM macro that accepts a path name as %1, you specify
`%__percompat_requires /path/to/executable`. That script receives a
newline separated list of paths as stdin and prints the generated
dependencies to stdout separated by newlines.
So perlcompat.attr could look something like
```
%__perlcompat_requires %{_rpmconfigdir}/perlcompat.req %{perl_version}
# %%__perlcompat_path can stay the same.
```
These are usually stored in %%{_rpmconfigdir}. %%{perl_version} is
passed to the script as an argument, because the script of course
doesn't have access to the RPM context. This can be any executable
written in any language, but it should be straightforward to do this in
shell.
Thank you for your advice.
The dependency generator would be added to perl-srpm-macros which is in
buildroot of Fedora.
So, I prepared package perl-srpm-macros-epel which should work for EPEL
7/8/9.
If you want to check it please look at
https://jplesnik.fedorapeople.org/perl-srpm-macros-epel/
I checked it in Copr
https://copr.fedorainfracloud.org/coprs/jplesnik/perl-epel/.
If the change is approved by FESCo, I'll prepared the review for the
package.
Then I'll ask you for adding it to epel-srpm-macros.
Regards,
Jitka
