I set up a linux machine without BLAS, LAPACK, ATLAS, hoping that lapacklite would take over. For the moment, I am not concerned about speed -- I just want something that will work with small matricies. I installed numpy, and it passes all of the tests OK, but it hangs when doing eig:

u, v = linalg.eig(rand(10,10)) # ....lots of nothing.... Do you need the linear algebra libraries for eig? BTW, inverse seems to work fine. -Rob

From ticket #5

Greg Landrum pointed out that it may be a gcc 4.0 related problem and proposed a workaround -- to add the option '-ffloat-store' to CFLAGS. Works for me !

Are you using gcc 4.0?
