Linker errors about soname

I have linker errors, while creating rpms for OpenSuSE. RPMS for Fedora are created correctly.

There’s no difference if I create symlinks to my library or not.
Part of log with error messages:

Hi
Have a read here;
https://en.opensuse.org/openSUSE:Shared_library_packaging_policy

You need to add %post and %postun with -p /sbin/ldconfig as well…

Thanks! I have build my package for many distribution. There’s still warning, but package was build. I don’t know, where should I put p switch. I have read manual page of ldconfig and it tells only p switch makes ldconfig more verbose. I inserted my .spec file below:

When my package will be searchable using software.opensuse.org?
