[yt-users] install/compile error

[Alexander Heger]

Dear Kacper,

I was able to install yt on my old python 3.4.3, but that was using gcc 
4.9.2 of Fedora 21.

OK, building new python 3.4.3 from scratch using same compiler:

~>python3
Python 3.4.3 (default, Sep 15 2015, 14:43:26)
[GCC 5.1.1 20150618 (Red Hat 5.1.1-4)] on linux
Type "help", "copyright", "credits" or "license" for more information.

now with that

~/Python-3.4.3>pip3 install -U yt
You are using pip version 7.1.0, however version 7.1.2 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Collecting yt
   Using cached yt-3.2.1.tar.gz
pipInstalling collected packages: yt
   Running setup.py install for yt
3 install --upgrade pip
Successfully installed yt-3.2.1

yt does compile successfully.  So the problem, it appears, indeed is 
with Python 3,5.0 alone.

Of course, I can't tell whether this is an issue with yt (seems less 
likely) or python 3.5.  If you think it is a python issue, please let me 
know, I am happy to submit a bug report.

Thanks for all your help.

Best wishes,
Alexander

PS - for mpl I often use their current development branch as well - I 
often have to fix things there...
