If you can't upgrade rpm, then rpm can't help you.
Is Suggests: really any different than the confusion induced
by vendor macros?
Technically, Suggests: is a compiled in token that depends on the
implementation,
while macros in principle can be changed without changing code.
Does it really matter? Is it that hard to add '#' in front of
Suggests:? Are there any users
and developers left who know how to use a text editor?
And the real problem is not Suggests: syntax, but rather semantic
interpretation, which
will invariably lead to implementation peculier interpretations that
*force* a much narrower
deployment context than what rpm or rpmbuild imposes.
Some places where might be useful are packages like pan - which
requires
gedit because it needs a text editor (and uses gedit by default in the
rpm), but could be configured to be used with a different one.
This works -
%define my_rpm_v %(eval "echo `rpm -q rpm |cut -d '-' -f2 |sed
s?'\.'?''?g`")
%define use_suggest %(eval "if [ %{my_rpm_v} -ge 443 ]; then echo 1;
else echo 0
; fi")
then later
%if %{use_suggest}
Suggests: foobar
%else
Requires: foobar
%endif
but I know it is wrong -
1) It assumes that rpm version will always be numbers, with only 3
fields
2) It assumes first rpm in path is what is building the spec file
3) Probably other stuff wrong with it.
If all you want is the rpm version predefined as a macro, I can do
that with 5-10 lines of
code. Less work than writing this e-mail message.
IMHO, that solves no problem whatsoever, as you *still* will have
versions of rpm around
that support Suggests: and won't have the blessed rpm macro.
Can you spell U-P-G-R-A-D-E?
What would be the best way to create a use_suggest macro so that the
spec file will build on rpm < 4.4.3 ?
Don't use what you cannot write and maintain reliably.
