[Numpy-discussion] build errors

Hi David,

Thanks for your reply. Nope, I didn't build the ATLAS libraries myself and am trying to do that now. However, whenever I try to build the shared libraries using the configure command:

[root@cn130 linux]# ../configure -Fa alg -fPIC --prefix=/gpfs/grace/atlas-3.8.4

it keeps building the static version. The ATLAS documentation stated that I need to provide the above flags to build the dynamic ones but this doesn't seem to work. 

Any help will be greatly appreciated. Thanks in advance.

Regards,
Wadud.
