That's fine, especially since you are creating it dynamically ;) You may have to specify the library files by hand as lib(64)?/ contains only links. The real libraries live in lib(64)?/openblas-<flavor>.

I'm not aware that I've thrown these out. On the packages I've worked on, I've converted the static baselibs.conf files to static ones as there was no good way to use static baselibs.conf file for all the different flavors - moreover, I don't want these 32bit binaries for HPC anyway. I've looked back, the version where I've claimed I added these, did not have it. Going further back I wasn't able to find any static baselibs.conf either, which makes me believe there was never any. I personally do not care for 32-bit libraries, neither professionally nor personally - at least for openblas. I had my fair share of openblas - the upgrade to 0.3.20 gave me some grief - and I do not want to invest any more time on topics that are of no interest for me. If you feel like a baselibs.conf setup is useful and want to create one *and* maintain it, please feel free. There were some breakages introduced thru my changes - which I've hopefully rectified, they had nothing to do with a missing baselibs.conf. These issues should disappear from Factory as the fix has been accepted last night. I have no idea who disabled build of openblas in science. It wasn't me - at least not intentionally. On the bright sight, switching between netlib-lapack and openblas should be possible, now.

openblas setup screwed in science project

Hi, someone has apparently disabled *all* builds for openblas. Whats the reason for this? As openblas 0.3.20 was never built inside science, we now have 0.3.20 in Factory and 0.3.17 (binary packages) in science. This causes a lot of unresolvables, as OBS tries to use openblas 0.3.17 from science. Kind regards, Stefan -- Stefan Brüns / Bergstraße 21 / 52062 Aachen home: +49 241 53809034 mobile: +49 151 50412019
