Dependency Generators in RPM < 4.9

[David Abdurachmanov]

Hi,

You could build your own macros/system for Provides/Headers management.

E.g., I have disabled internal dependency generator (libtool):

%_use_internal_dependency_generator	0

Then inside the SPEC you could so something like that:

# Filter out private stuff from RPM requires headers.
cat << \EOF > %{name}-req
#!/bin/sh
%{__find_requires} $* | \
sed -e '/GLIBC_PRIVATE/d'
EOF

%global __find_requires %{_builddir}/gcc-%{gccBranch}-%{gccRevision}/%{name}-req
chmod +x %{__find_requires}

Inside build directory you create %{name}-{req,prov} bash scripts, which calls the original one (if you need it) and then you add/remove items you want. Then inside the SPEC you change the %{__find_requires} script used by RPM. I do it in %prep section.

It works on Scientific Linux 5 (RHEL 5).

I believe Fedora has defined some nice macros for managing provides/requires in their build system.

Cheers,
david
