[Numpy-discussion] build errors

[Miah Wadud Dr (ITCS)]

Hi again, 

I have built the ATLAS dynamic shared libraries and now need to tell numpy to build against them which are located in a different location to where it expects them. Do you know how I can do that? The command I am using to build numpy is:

python setup.py build --fcompiler=gnu95

but this looks in /usr/lib64/atlas and I need it to look in another location (/gpfs/grace/atlas-3.8.4). 

Thanks in advance,
Regards.
