[Python.NET] Python 3.4 Support

[Beckett Simmons]

Hello all,
I am trying to get pythonnet to build with python 3.4. I am on a Windows 7 64-bit machine and specifically want to use Python 3.4.1.
Of course the official repository on github does not support python 3.4 yet.
I've tried this fork here: https://github.com/renshawbay/pythonnetBut that is not working for me. Running setup.py give me this error: ValueError: close_fds is not supported on Windows platforms if you redirect stdin/stdout/stderr
Also, checked out http://www.lfd.uci.edu/~gohlke/pythonlibs/#pythonnet for a Windows precompiled binary, but they only have the python 3.3 version there.
Any other ideas or ways I could use pythonnet with Python 3.4?

Hi,

use setupwin.py instead of setup.py in the renshawbay repo to build it.

cheers,
Tony

Hey Tony,
Thanks for the help. I was able to build pythonnet with your instructions.
The issue that I am having now is that pythonnet seems to be build for python33.When I try to import clr I get this error and python.exe crashes.http://pastebin.com/0zcW6nP0How would I possibly point pythonnet to the correct python34 DLL?

This is what my build looks like: http://pastebin.com/Gb4K5PZS
I would be worth while to note that I am building and running python on a virtual environment that comes from a python 3.4.1 64-bit base install. Would this possibly be the problem?

Hi,
yeah it definitely does build for x64. That's what I use mostly, in fact.
I think the 64 bit compilers don't come as part of visual studio express.
You can get them as part of the windows sdk download from msdn though. You
might struggle to get it to work with distutils/setup tools as they expect
the compiler to be installed as part of visual studio. What you'll need to
do is start a prompt with all the compiler stuff setup and set the env var
DISTUTILS_USE_SDK=1 to tell distutils to look at the current environment
for the compiler instead of the registry.
cheers,
Tony

Hey Tony,
Thanks for your fast reply.
Your answer got setupwin.py to build for me, but only with Python 3.4
32-bit.
File "C:\Python341\Lib\distutils\msvc9compiler.py", line 287, in
query_vcvarsall
raise ValueError(str(list(result.keys())))
I am assuming that this is a compiler error because it doesn't have a
64-bit compiling function. I used the same compiler at the 32-bit build
with was Visual C++ 2010 Express. And I also tried Visual Studio 2012
Express too. (Making sure to adjust my environment path accordingly.)
I just want to confirm that this is indeed a compiler issue and doesn't
have to do with the pythonnet code itself.
Thanks,
Beckett

Hi Becket,

hmmm, did you build it for 3.3 previously? The setupwin.py in this repo
doesn't clean before building and re-uses the same target for the different
python versions so it won't rebuild everything correctly when switching
between python versions. Try deleting all the build folders and re-build.
It's a bit rough and ready; the setup.py in the official repo works better.

If that doesn't work let me know as I had it working ok (but I'm still
using 3.2 mostly so it hasn't had much testing).

cheers,
Tony
