Wouldn't downloading the Microsoft C++ Runtime 2015 also work? I'm sure it would -- I know that installing the entire MSVC2015 Community Edition does...

but the point here is that end users should be able to:

pip install something

and if there is a binary wheel for something, it should work without them having to install something else. (why MS doesn't ship ALL their runtimes with eh OS is beyond me...)

As it stands now, there are two options:

  1. users need to install something else themselves: the runtime, that particular dll, the compiler...
  2. every package maintainer that uses C++ needs to ship that dll with the binary wheels.

If we put the dll into the python binary, then it would "just work"

Many recent computers already have it pre-installed.

Hi folks,

The standard build of Py3.5 for Windows is built with VS2015 (correct??) And it includes the runtime dlls it needs. However, we've found that wxPython wheels for win32 (not sure about win64) also need: MSVCP140.DLL So: wxPython could include that of course, But it looks like it's getting included with the Matplotlib wheels already (so folks with Matplotlib can run wx....). I'm just guessing, but this looks like the standard run time for C++ with that compiler. Python itself doesn't use C++, of course, but maybe we should include that dll with Python anyway -- that way folks can build wheels of packages with C++ extensions in the normal way, and those wheels will "just work", and we don't have to have every individual package ship the same dll. -CHB
