M2Crypto Wheels

About

This repository contains builds of M2Crypto for Windows based on these instructions.

If you have build your own, send a Pull Request to integrate them here so we can help others too! 🙂 🚀

Instructions

Steps >=7 can be simplified running the builder.ps1 script

  1. Install the latest Build Tools for Visual Studio 2019. See https://visualstudio.microsoft.com/downloads/ under "All Downloads" -> "Tools for Visual Studio 2019". This direct link was active as of this writing: https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16
  2. In the installer, select "C++ Build Tools", install, and reboot if necessary.
  3. Install the latest full (not Light) OpenSSL for your architecture (Win64/Win32). Current version as of this writing is 1.1.1d. Make note of the directory to which you install OpenSSL. https://slproweb.com/products/Win32OpenSSL.html
  4. In PowerShell, install the Chocolatey package manager. I used this command from their website: Set-ExecutionPolicy Bypass -Scope Process -Force; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
  5. Install swig with Chocolatey (in PowerShell). choco install -r -y swig
  6. Install the pywin32 dependency. Run pip install pywin32. If you have problems, try first running pip install wheel. To get pip to target a specific Python installation, try launching it using py -[version] -m pip install [module]. Note: you may need to use an elevated (administrator) PowerShell to install Python modules.
  7. Get the latest m2crypto code. If you have git installed, run git clone https://gitlab.com/m2crypto/m2crypto. Otherwise, download and extract the code from GitLab: https://gitlab.com/m2crypto/m2crypto/-/archive/master/m2crypto-master.zip
  8. Use cd to change into the directory m2crypto was cloned/extracted to.
  9. Assuming python launches your desired Python interpreter version, run python setup.py build --openssl="C:\Program Files\OpenSSL-Win64" --bundledlls, replacing C:\Program Files\OpenSSL-Win64 with the directory to which you installed OpenSSL. (On some systems you can use the py launcher to specify a Python version to use, run py -h for more information.)
  10. Generate the installable files. python.exe setup.py bdist_wheel bdist_wininst bdist_msi.
  11. Install the module. cd into the dist directory and run pip install M2Crypto-0.35.2-cp38-cp38-win_amd64.whl, replacing the filename with the generated .whl file. If you have problems, try first running pip install wheel. To get pip to target a specific Python installation, try launching it using py -[version] -m pip install [module]. Alternatively, you can run the generated .exe or .msi installer. Note: you may need to use an elevated (administrator) PowerShell to install Python modules.
