Comment (by fbissey):
I spent quite some today working on `fflas-ffpack-2.2.0` for sage-on-
gentoo, expect a PR shortly to fix the tests when `fflas-ffpack` has been
configured with `--enable-precompilation` (not that the test will work if
you previously installed `fflas-ffpack` with `--enable-precompilation` in
a standard location - do I need to say more).
`lapack`, and even probably `ATLAS`' clapack interface, is detected
properly but you have to pass all the libraries for `lapack` and `cblas`
in the `--with-blas-libs` switch. With our new `.pc` files that should
translate to
{{{
--with-blas-cflags="$(pkg-config cblas --cflags)" --with-blas-libs="$(pkg-
config lapack --libs)"
}}}
Although it would probably be safer to put
{{{
--with-blas-cflags="$(pkg-config cblas --cflags)" --with-blas-libs="$(pkg-
config lapack cblas blas --libs)"
}}}
in case `lapack.pc` doesn't pull either or both `cblas` and `blas`.
`sage` run `spkg-check` after install (a bit daft but hard to fix with the
current system) so we should also be ok to add a `spkg-check` to `fflas-
ffpack` without including my upcoming PR.
