This was not the error (just a warning). Problem is

With the option --without-system-openblas, the compilation fails at

just on this 10 days ago.
the system's openblas on Arch is broken, so you'd need to build with
---without-system-openblas

Dear all,
I am experiencing trouble compiling fflas_ffpack (in the sage
compilation process). It is the same error appearing multiple
times related to openblas_set_num_threads being not declared.
Note that I am running archlinux.
Best
Vincent
