Re: [yt-users] ramses_reader broken on Lens?

Yeah after updating, now matplotlib is complaining. I'll see if they can install/find the missing software, I don't think it is feasible to rewrite all my scripts just for this one machine. From G.S.

Actually, it's a different error. Now you're getting it from the ART import. I have made the same modification there in 749ce1a696de.

The error is still with your environment; it's telling you right in the error message that it's unable to find GLIBCXX. This is the C++ standard library. I would bet that you will run into more problems down the line -- probably with matplotlib. However, you should be able to make image plots and serialize data with cPickle to avoid having to use matplotlib.

Hi Geoffrey,

If I understand your email correctly, you are loading the GNU environment correctly, but it's not entirely clear to me from reading it.  I've pushed a fix that will allow ramses_reader to fail silently on import.  This is in changeset 716698ff4046.

You may get similar errors with Matplotlib.

Loading PE-pgi will only complicate matters.

I thought I might have used PE-pgi, so I went and reinstalled YT with the PE-gnu loaded, and installed mpi4py afterwards with the same window specifying --home=/ccs/home/geoso/LensYT when I did the python setup.py install.  And I'm still getting the same error.  I think I recall if I had PE-pgi loaded, mpi4py wouldn't even build.

I've even tried loading pgi to run the script and still the same error.

Hi Geoffrey,

This is usually caused by having the wrong programming environment loaded when you run or build yt.  Did you have GNU loaded when you built, and do you have it loaded now?

The reason it shows up with Ramses is that Ramses uses C++.

I was trying to test Lens with a fresh install of the devel YT and some simple projections and I got the following:

Traceback (most recent call last):  File "moviesDens.py", line 3, in <module>    from yt.mods import *  File "/autofs/na1_home/geoso/LensYT/src/yt-hg/yt/mods.py", line 71, in <module>    from yt.frontends.ramses.api import \  File "/autofs/na1_home/geoso/LensYT/src/yt-hg/yt/frontends/ramses/api.py", line 31, in <module>    from .data_structures import \  File "/autofs/na1_home/geoso/LensYT/src/yt-hg/yt/frontends/ramses/data_structures.py", line 37, in <module>    import _ramses_reader ImportError: /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.11' not found (required by /autofs/na1_home/geoso/LensYT/src/yt-hg/yt/frontends/ramses/_ramses_reader.so)

Is this missing GLIBCXX_3.4.11 YT's problem or should I email the NCCS sys admins?
