Except that it is terribly out of date (3.4.1 is maybe 5 years old or something). And we all know the pathetic state of linux when trying to distribute binary/distribution independant only anyway (it is basically impossible without huge ressources most open source projects do not have).
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.
The problem is that this is not possible. You can't build a generic version: if I have a CPU with SSE3, it is not possible to build ATLAS without SSE3 instructions. This is a PITA, because even on the same machine, it is not possible to generate the exact same binary (debian does it by recording the build output and replaying it....).
Also, I don't know if that software offers a library. If it does you may need the generic version for linking other applications.
No, it does not ATM. Trust me, I have some knowledge about building ATLAS on various platforms (including but not limited to linux), more than I wish I had: I am a core developer of numpy, which optionally depends on Atlas, and it is the number one problem wrt deployment for us. Most distributions screw up those packages (blas/lapack/Atlas), BTW. I would understand that it is not a big user-case for the build service; but it is a case where source rpm only are useful, and binary rom next to impossible to support correctly (reproducible build, for once). cheers, David --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org
