just a question, do we have a use case somewhere, where only a src.rpm should get build, but no binary packages ?
yes, ATLAS:
http://math-atlas.sourceforge.net/
It is an optimized BLAS/LAPACK library, useful for numerical computation. The optimization is based on running many different tests during the build, and the performances are CPU dependant (depends on the L1/L2/L3 cache size, etc...). This means it is not possible to build it as an rpm, but a src.rpm is still useful (since the user only has to run rpmbuild bla bla).
http://math-atlas.sourceforge.net/faq.html#binary | Can I download a prebuilt binary instead of installing from source? | We provide prebuilt ATLAS libraries for some selected architectures/configurations. Even if the software is able to optimize itself better by compiling it on the target processor you could still build a generic version for the architecture. Those who need the last bit of performance can still rebuild the source then. Also, I don't know if that software offers a library. If it does you may need the generic version for linking other applications. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
