Re: installing PyNGL from source

Matt,

As I said, I don't have much familiarity with this, but on my own Mac, I finally had to give up using the system "python", because it was built for multiple architectures and it didn't want to load a PyNGL or PyNIO module that was compiled for a single architecture.

So, what I did was compile python myself from source code, and I set the following environment variables before I ran the python "./configure --prefix...":

setenv CC gcc
setenv CXX g++
setenv FC gfortran
setenv F77 gfortran
setenv CFLAGS '-m64 -fPIC -Df2cFortran'
setenv FFLAGS '-m64 -fPIC'
setenv F90FLAGS '-m64 -fPIC'
setenv CXXFLAGS '-m64 -fPIC'

I was then able to compile PyNGL using this python.
