Thanks — upgrading setuptools did indeed fix the problem. I installed via pip install setuptools —upgrade —user to override the NASA-managed older version.

Just in case it's not clear from that thread: "pip install -U setuptools" should fix it. I'm not sure if you're going to be able to do that using the python installation you're using that's managed by Nasa, in which case I'd suggest setting up your installation using the get_yt.sh script, which installs yt into a miniconda environment:

I think this is because of a not-up-to-date setuptools package. I'm not 100% familiar with the specifics, but this ticket goes over how to address it: https://bitbucket.org/yt_analysis/yt/issues/1169/document-issue-with-old-set... <https://bitbucket.org/yt_analysis/yt/issues/1169/document-issue-with-old-set...>

Hi yt Users,

I’m having a problem compiling the current development branch of yt on NASA pleiades, and I’m hoping that someone can suggest what could be going wrong. Here’s what I get when I try to compile:

bridge4:yt mkrumhol$ /nasa/python/2.7.9/bin/python setup.py develop --prefix=/u/mkrumhol running develop running egg_info writing requirements to yt.egg-info/requires.txt writing yt.egg-info/PKG-INFO writing top-level names to yt.egg-info/top_level.txt writing dependency_links to yt.egg-info/dependency_links.txt writing entry points to yt.egg-info/entry_points.txt reading manifest file 'yt.egg-info/SOURCES.txt' reading manifest template 'MANIFEST.in' warning: no previously-included files found matching 'scripts/pr_backport.py' no previously-included directories found matching 'doc/source/reference/api/generated' no previously-included directories found matching 'doc/build' writing manifest file 'yt.egg-info/SOURCES.txt' running build_ext pyrexc yt/analysis_modules/photon_simulator/utils.pyx --> yt/analysis_modules/photon_simulator/utils.c /home3/mkrumhol/yt/yt/analysis_modules/photon_simulator/utils.pyx:6:17: Syntax error in C variable declaration building 'yt.analysis_modules.photon_simulator.utils' extension gcc -fno-strict-aliasing -O2 -Wno-error -pipe -DHAVE_DB_185_H -pthread -I/usr/include -I/nasa/pkgsrc/2014Q4/include/db4 -I/nasa/pkgsrc/2014Q4/include -DNDEBUG -O2 -Wno-error -pipe -DHAVE_DB_185_H -pthread -I/usr/include -I/nasa/pkgsrc/2014Q4/include/db4 -I/nasa/pkgsrc/2014Q4/include -fPIC -I/nasa/pkgsrc/2014Q4/include/python2.7 -I/nasa/pkgsrc/2014Q4/lib/python2.7/site-packages/numpy/core/include -c yt/analysis_modules/photon_simulator/utils.c -o build/temp.linux-x86_64-2.7/yt/analysis_modules/photon_simulator/utils.o gcc: yt/analysis_modules/photon_simulator/utils.c: No such file or directory gcc: no input files error: command 'gcc' failed with exit status 1

I’m using python 2.7.9 and cython 0.23.4. The problem only occurs with the development branch; the stable branch compiles fine.

I’d appreciate any suggestions. Thanks.
