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. >-----Original Message----- >From: numpy-discussion-boun...@scipy.org [mailto:numpy-discussion- >boun...@scipy.org] On Behalf Of Miah Wadud Dr (ITCS) >Sent: Thursday, October 06, 2011 11:12 AM >To: Discussion of Numerical Python >Subject: Re: [Numpy-discussion] build errors > >Hi David, > >Thanks for your reply.
