I don't think RPM supports arch modifiers (like i686+sse2). Does it?
Nope, you will have to build an i686 package with -msse2 in that case.
Well, yeah. What I meant is marking the package as using sse2, and making rpm know not to install it on hardware that doesn't have sse2 (or auto-select any working alternative), so you could build both i686 and i686+sse2 versions and have the best of both worlds.
Nope.. no such feature exists unfortunately.. the only sort of thing that exists is a mechanism for providing shared libraries with or without particular CPU features enabled.. for example in factory you will find in /lib/noelision/ a version of libpthread without Intel TSX support, same can be done with other CPU features. Unfortunately it is an unspecified implementation detail..in the sense it is not documented how to use it, or at least there was no info last time I checked. -- Cristian "I don't know the key to success, but the key to failure is trying to please everybody." -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
