Re: [sage-devel] Re: [ARM] sage 6.5
In spkg-install you need to add a suitable branch in configure_base():

NotImplementedError: I don't know a base configuration for your cpu.
I think something should be done in the configure_base function -- but
since I haven't found how from configuration import conf works, I
don't know exactly how to make that work.
Pointing to a specific location for the atlas library isn't going to be
much use in a binary that we distribute.
As pointed out by J.-P. Flori, ARM is a generic name for a whole
processor family, so providing something which works everywhere isn't
easy... or even possible.
Still, we can perhaps shoot for something better.

The base configuration is supposed to be a fixed one. If you want to tune
for your respective cpu then we can do that already.
