RPM's might have too many provides

[anders.blomdell@…]

The rpm's provided by openmodelica has provides of many bundled
libraries that might make other packages that depends on those
provides fail if openmodelica gets loaded instead of a rpm that
has that library in the ordinary library paths(s)

openmodelica-1.12 = 1.12.0~9~g6f68ff6-1.fc27
openmodelica-1.12(x86-64) = 1.12.0~9~g6f68ff6-1.fc27

Adding something like this in the .spec file might be a good idea:

%global __provides_exclude_from ^/opt/openmodelica-1.13/lib/x86_64-linux-gnu/omc/.*$
%global __requires_exclude_from ^/opt/openmodelica-1.13/lib/x86_64-linux-gnu/omc/.*$

We can't remove the requires though (or the correct dependencies would not be installed)...

​https://fedoraproject.org/wiki/Packaging:AutoProvidesAndRequiresFiltering suggests a pattern like:

%global _privatelibs libprivate[.]so.*
%global __provides_exclude ^(%{_privatelibs})$
%global __requires_exclude ^(%{_privatelibs})$

But we don't know the list of shared objects until we have compiled it, so I guess we would need to read this dynamically.

[Martin Sjölund]

export PRIVATELIBS=`find %{buildroot}/opt -name "*.so" -exec basename {} ";" | tr '\n' "|" | sed -e "s/[.]so/.so.*/g" -e "s/|\$//"`
%global _privatelibs $PRIVATELIBS
%global __provides_exclude ^(%{_privatelibs})$
%global __requires_exclude ^(%{_privatelibs})$

Didn't seem to work :(

I'm trying this commit on our build system (disabling auto-provides; as long as we can install the generated rpm, it should be working):

That seems to have worked fine for Fedora and CentOS7, but CentOS6 is too old for that. So I will add some requires manually and let the RPM sometimes be broken on CentOS6 instead :(

Actually, milestone has no real meaning here: they are rebuilt also for 1.9.6 :)
