[daip] New AIPS problem

[Jose' Manuel Afonso]

Hi Eric,
I installed the AIPS binaries (install -n) in my AMD64 laptop, and it is 
now working perfectly, as far as I can tell. I had to install libncurses 
for 32bit architecture (I had it, but only for the 64bit - since the 
binaries are 32bit, they were looking for a different library...), but 
that was it.

(I was planning to install the intel compilers here and compile everything 
from scratch, for a possible performance improvement, but installing the 
intel compilers started giving me some headaches. Considering the 
performance you achieved with the 32bit pre-compiled and gnu local 
compilation, I guess any improvement from a local compilation with intel 
compilers would not be huge, so I will stick with the aips binary version 
for now).

Thanks a lot for your help!

Jose
