I’m struggling to build Python 3.11 alpha 0 from source on Windows 10.
Steps I have taken:
- Successfully installed Microsoft Visual Studio.
- Successfully Installed git on my machine.
- Successfully forked the CPython main branch on GitHub.
- Successfully cloned my forked branch onto my local machine.
- Navigated to the cpython repo folder on the command line.
PCbuild\build.bat -e -d -p x64
The error I receive is:
Build FAILED. LINK : fatal error LNK1104: cannot open file 'libffi-7.lib' [C:\Users\Alex\Desktop\Code dump\cpython\PCbuild\_ctypes.vcxproj] 0 Warning(s) 1 Error(s)
This appears to be the only error that takes place during the build process; the rest of the build works fine. It appears as though there is no file on my PC named
libffi-7.lib. It does appear as though I have several files named
libffi-8.lib. These can be found in the following locations:
I am using the following hardware and software versions:
- Microsoft Windows 10 Home, Version 10.0.19043 Build 19043
- A x64-based PC
- An HP Pavilion Notebook laptop
- Processor AMD A8-7410 APU
- git version 2.24.1.windows.2
- Microsoft Visual Studio 2017.
- The build appears to be using an installed copy of Python 3.8 on my machine, which was installed with Conda.
- The build informs me it is
Using "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\msbuild.exe" (found in the Visual Studio installation)
Variations on the build command I have tried, that have had no effect on the problem:
- I initially tried building Python with Visual Studio 2019, and received the same error message. I then uninstalled Visual Studio 2019, installed Visual Studio 2017, and tried again. This had no effect on the error message that I received.
- I tried running
PCbuild\build.bat -E -d -p x64instead of
PCbuild\build.bat -e -d -p x64. This made no difference; the build failed in the same way, although I did get an additional warning informing me that
Not including zlib is not a supported configuration.
- I tried deleting the local copy of my forked branch and re-cloning it. This made no difference.
- I tried enabling the
.NET Framework 3.5 (includes .NET 2.0 and 3.0)on my machine. This made no difference.
- I tried restarting my computer. This made no difference.
Does anyone have any ideas as to what might be going wrong and/or how to fix it?
