Ready to use wheels for those who have cried enough trying to install M2Crypto on Windows

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.

m2crypto-wheels's Issues

Builds from master branch of m2crypto are broken on Windows

I tried to build m2crypto from current master branch but it failed with "libssl.so not found" errors, the setup.py doesn't handle Windows environment correctly anymore (I guess it's a bug).

So the README should suggest people to target the release branches through git clone's --branch argument:

git clone --branch 0.38.0 https://gitlab.com/m2crypto/m2crypto
cd m2crypto
python -m venv venv --prompt=m2crypto
.\venv\Scripts\activate
python -m pip install wheel pywin32
python setup.py build --openssl="C:\Program Files\OpenSSL-Win64" --bundledlls
python setup.py bdist_wheel
