Hi William,
i´ll do so soon.
I could build sage with gcc-4.0. But there´s a problem with my
libblas.so.
If i try to import cvxopt, i´ve got the following error:
sage: import numpy
sage: from cvxopt.base import spmatrix
---------------------------------------------------------------------------
<type 'exceptions.ImportError'> Traceback (most recent call
last)
/opt/sage/<ipython console> in <module>()
<type 'exceptions.ImportError'>: /usr/lib/libblas.so.3: undefined
symbol: _gfortran_runtime_error
sage:
As you can see, importing numpy was succsessfull.
