Re: PyTrilinos import error Mac OS

[Guyer, Jonathan E. Dr. (Fed)]

Apple moved something between 10.11 and 10.12. It looks like my rebuild for 
10.12 from a few weeks ago broke 10.11. I'll have to figure out how to post 
both versions (and rebuild the 10.11 version at all).

PyTrilinos import error Mac OS

[Seufzer, William J. (LARC-D307)]

I get the following error on Mac OS 10.11.6 (Xcode 8.2.1 w/ command line tools 
installed). I used:

conda create --name pytril --channel guyer --channel condo-forge fipy

to create the environment (BTW, thanks for setting that up!!)

Father Google doesn’t seem to be of any help on this one.

The error:

I’m on a centrally managed Mac, so OS update is not an option. Xcode, gcc, and 
Conda install are under my control.

Thanks,
