Hi there
I have a group of packages that i have to create different versions
based on the compiler brand and version.
These variables ( compiler brand and version ) define some features of
the binary rpms i'm generating,
like "%_prefix", "%release" , "%optflags" and so on ...
My idea is to make something like this http://pastebin.com/EHKwE59C
Macro files are not shell scripts, that's a no-go. Another problem here
is the use of %define within conditionals:
{!?compiler_version: %define compiler_version 4.4}
You need to use %global instead of %define there, otherwise you'll
encounter some bizarre effects sooner or later: technically such a
nested define falls out of scope immediately, but might not be actually
"garbage collected" until much later.
I can do it with a few "%if ... %else ... %endif" , in the package spec file,
but i'd like to put in ~/.rpmacros to avoid the copy & paste to every
.spec file. Eeek!
You can avoid copy-paste by putting the common part into a separate file
and pull it into specs with %include.
I also tried the lua bindings, but no deal too.
What was the actual problem here? Lua is basically the best/only way to
get arbitrarily complex things done inside macros.
