Describe the bug
A clear and concise description of what the bug is.
(Issues related to the runtime files should be reported to their maintainer, check the file header.)

To Reproduce
Detailed steps to reproduce the behavior:

  1. clone https://github.com/vim/
  2. install MS VisualStudio 2019
  3. execute "vcvars64.bat"
  4. install Python (I used WinPython, 3.8.6, into the folder "C:\Programs")
  5. go to the cloned repo, into the "src" folder, and type
    make -f Make_mvc.mak GUI=yes PYTHON=C:\Programs\WPy64-3860\python-3.8.6.amd64 PYTHON_VER=38

This leads to the following output:

Expected behavior
The build should run through. (Note that the build DOES work without the PYTHON options!)

try the official python: https://www.python.org/ftp/python/3.9.0/python-3.9.0-amd64.exe That is what is used for the vim-win32-installer repository and this one works.

You are specifying PYTHON and PYTHON_VER options, but you should use PYTHON3 and PYTHON3_VER options instead.
Adding DYNAMIC_PYTHON3=yes might be better.

Hello, I am trying to do the same thing, but without the dynamic option and the compilation fails on both python2 and python3. These are my commands for the compilation using VS:

Python2: nmake -f Make_mvc.mak GUI=yes PYTHON=C:\Users\gou\Miniconda3\envs\py27 PYTHON_VER=27
Python3: nmake -f Make_mvc.mak GUI=yes PYTHON3=C:\Users\gou\Miniconda3 PYTHON3_VER=37

...
if_python3.obj : error LNK2001: Nicht aufgelöstes externes Symbol "__imp__PyEval_RestoreThread".
gvim.exe : fatal error LNK1120: 105 nicht aufgelöste Externe
NMAKE : fatal error U1077: ""C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.29.30133\bin\HostX86\x86\link.EXE"": Rückgabe-Code "0x460"
Stop.

There are many LNK2001 errors, but i cut them off to not spam the window. The win32 installer provides Python support, but only dynamic, which doesn't seem to be acceptable for some plugins, i.e. vimspector.

Does anyone have an idea how to fix the problem? It seems to be a Windows issue (surprise surprise) because i compiled vim fine on linux. The win32 installer provides Python support, but only dynamic, which doesn't seem to be acceptable for some plugins, i.e. vimspector.

Thanks in advance.

Can you please try with a standard python without anaconda?

can you please try with official python package and not some other distrution?

The win32 installer provides Python support, but only dynamic, which doesn't seem to be acceptable for some plugins, i.e. vimspector.

I don't think this is true. you should be able to simply load the library and then it should work. Ping @puremourning please correct me if I am wrong. Thanks!

@chrisbra you're not wrong... I only ever use your builds of vim for windows and they work fine with vimspector and YCM

Hello,

thanks a lot for the prompt responses, and amazing work @puremourning :).

Unfortunately for me, Vim installed via the Windows installer (with both versions of Python included dynamically) gives me a warning that vimspector needs the +python3 option. I tried doing some basic things like setting a breakpoint or installing an adapter after closing the warning, but nothing happens, so i assume that the plugin is not loaded. Can it really be due to the fact that my python installation is not in C:? I'd prefer to stick to the conda environment if it's possible.

Thanks in advance.

you may need to set the :set pythonthreedll=c:\path\to\python\dll. Just make sure that if you use a 32bit vim you also use the 32bit python dll. I am not sure if miniconda/anaconda will always work.

start vim with gvim -Nu NONE and run :py3 pass. If this doesn't work, then python3 plugins won't work.

It's likely that either:

  1. your python does not match the architecture of your vim (both must be 32 or both 64 bit)
  2. your python dll is not in your PATH
  3. your python is not python 3.6, which is the version that vim is compiled against in your screenshot.

The simplest way to double-check this and make it work is to :set pythonthreedll=<path> where <path> is the path to the actual python36.dll in your python installation.

I got it working :) :) Thanks a lot.

Now i'm having an issue with the vscode-cpptools adapter. During installation the archive is extracted, then removed, and then the installation crashes because a file in the now removed directory doesn't exist.

If you know the answer right away that'd great, but if this should be put in a new issue, then i'd be happy to do that.

That is a vimspector-related question, not a vim-related question. Check the Vimspector docs and contributing guide for how to go about it.
