Because of that, this technique really doesn't work for this package.
For this RPM, I want to conditionally select which patch to apply based on the
version of he installed gnupg package on the system it is building on.
rpmbuild already has this information somewhere internally as it can compare
versions for BuildRequires: lines.
I'm looking for "something_that_gets_version" to use something like this:
%define gnupg_version "%something_that_gets_version gnupg"
%if "%gnupg_version" = "1.2"
Patch1: GnuPG-Interface-0.33.test-results-1.2.patch
BuildRequires: gpg = 1.2
%else
Patch1: GnuPG-Interface-0.33.test-results-1.4.patch
BuildRequires: gpg >= %{gnupg_version}
%endif
I need it to work for all sorts of distros, not just RHEL, FC and not just
within buildsystems.
Is there such a mechanism available for use in the SPEC file or do I need to
execure an external rpm command to query for that on my own?
