yes in principle all blas packages can be affected by this, but only lapack uses the hardening flags and thus -Wl,-Bsymbolic-functions. To be safe it should probably be preemptively stripped from all and tests added, numpy or scipy is a good place to test it, as it tries its tests with all blas options (in ubuntu). -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
