[issue25150] yt package pip compile/install error

[Alexander Heger]

New submission from Alexander Heger:

trying to install the yt package, most recent version 3.2.1 on python 3.5.0 
using pip

pip3 install -U yt

error output attached.  The same package installs fine with python 3.4.3, same 
compiler and also build from scratch, so the suspicion is that it is related to 
the new 3.5.0 version.  The system installed is the current Fedora 22, gcc 
5.1.1-4.

[issue25150] yt package pip compile/install error

[STINNER Victor]

STINNER Victor added the comment:

It looks like the problem is that yt uses OpenMP whereas OpenMP doesn't support 
atomic operations:

In file included from /home/alex/Python/include/python3.5m/pyatomic.h:12:0,
 from /home/alex/Python/include/python3.5m/Python.h:53,
 from 
build/src.linux-x86_64-3.5/yt/utilities/lib/geometry_utils.c:4:
/usr/lib/gcc/x86_64-redhat-linux/5.1.1/include/stdatomic.h:40:1: sorry, 
unimplemented: ‘_Atomic’ with OpenMP
 typedef _Atomic _Bool atomic_bool;
 ^

I'm not sure that Include/pyatomic.h should be included by the main 
Include/Python.h header. We already skipped Include/pyatomic.h on C++ because 
this header is incompatible with C++.
