How to recompile openblas ------------------------- Some notes about how to recompile packages from unstable: ``_ Openblas with Sandybridge target support is available in the experimental repository in debian. I recompiled it as follows: TARGET=SANDYBRIDGE USE_OPENMP=1 apt-get -b source openblas By default, it uses pthreads, instead of openmp, which was interfering with other use of openmp in my code. If we dont' specify the target, it builds a lot of different architectures, and the right one gets selected at runtime. Unfortunately it doesn't include Sandybridge yet.
