Re: [python-win32] Using pip to install pywin32
Pywin32 is mostly written in C, and has lots of dependencies and weird build requirements. In order to compile it, you must have the same C compiler that your release of Python was built with. For older Python versions (like 2.7) that compiler is obsolete and hard to find, so installs from source are pretty nearly impossible. Would a binary wheel be able to do all of the crazy set up that the Windows installer does? The project is open source, and patches are happily accepted.

[python-win32] Instructions for building and installing Python 2.7 on Windows with VS 2013 or newer
Hi, I've successfully used the solution in the PCBuild directory to build CPython. However, now I have a binary and collection of .pyd files that aren't really a coherent installation. How do I do the equivalent of a make install step on Windows? My ultimate goal is to get a directory that looks like the C:\Python27 directory produced by running the official MSI download. I suspect the easiest way to achieve this is to build such an MSI and then run it. That's totally fine with me. I've done a fair amount of searching, but I've found results like the following which just have scripts that manually copy files into place in a way that sort of looks like an official installation. I'd like to do things the canonical way, if possible. I haven't been able to find this anywhere in docs.python.org, but maybe I'm blind. http://docs.python-guide.org/en/latest/starting/install/win/ Thanks!

I don't know anything about Python implementation internals, but is something like this possible? I've no idea, my previous post pretty much exhausted my entire knowledge of the building of Python extensions for Windows :) But that sounds like a great topic for python-ideas or python-dev... and a PEP, and a lengthy period of bikeshedding, and lots of people telling you it isn't possible, and lots of other people telling you it's easy...

No it wouldn't, but a lot of the postinstall stuff isn't necessary for many uses of pywin32. It's probably still worthwhile to package it as a wheel for those use cases. At least it's useful enough that there's an alternate distribution called pypiwin32: https://pypi.python.org/pypi/pypiwin32 The project is open source, and patches are happily accepted. According to the bug I referenced above, the only thing necessary to get most functionality working is a tweak to the path files. Also according to the same bug, it looks as though those involved couldn't figure out where to send patches. Where should patches/contributions be sent in order to get the attention of those who can merge them?

I don't think pip can run this script (it even needs admin privs!). Is there a reason it couldn't run a script that presents a UAC prompt to elevate the process? Something like this: https://gist.github.com/Preston-Landers/267391562bc96959eb41 I guess for unattended installs you could just elevate the process beforehand. -Preston On Fri, Feb 20, 2015 at 9:24 AM, Thomas Heller thel...@ctypes.org wrote: Am 20.02.2015 um 15:07 schrieb Vernon D.

And is anyone aware of any ways to get around this restriction so that i can write an extension module that will work with a binary release of python? It's going to be better, starting from Python 3.5; Microsoft is guaranteeing a measure of binary compatibility for future compiler versions. Unfortunately the guarantee requires some internal changes, so it's moving forward only, not backward. The fate of Python 2.7 is very much up in the air, because the compiler that was used for 2.7.0 won't be supported in 2020 (I think it might be already out of support), so there's a big question of whether or not to change compilers in the middle of a minor version.

Are there any workarounds? It's really quite an inconvenience. If the reason is because python27.dll and the extension module free each others' memory, then it seems like this could be solved by having each supply the other with an alloc and free function pointer, and using the correct allocator on each side. Is the situation better in python 3 than it is in 2.7?
