This answer is based on the GitHub comment at https://github.com/iOSForensics/pymobiledevice/issues/25#issuecomment-576119104, for a Python module that requires m2crypto.
Some builds for m2crypto for specific versions of Python are available from their CI: https://ci.appveyor.com/project/m2crypto/m2crypto/history. Try selecting a version, selecting a job that matches your Python version, then going to the "Artifacts" tab and downloading an installer. To install a .whl file, see step 11 of my build tutorial below.
M2Crypto-0.35.2.win-amd64-py3.8.zip is the m2crypto module that I have built on Windows 10 x64, Python 3.8.1. It should work on any x64-based version of Windows with any version of Python 3.8.X.
However, if you are unable to find a build that matches your Python version and system type and architecture, you may need to manually build m2crypto. I adapted the build steps from their CI build scripts: https://gitlab.com/m2crypto/m2crypto/blob/master/appveyor.yml. I built the module by doing the following:
- 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
- In the installer, select "C++ Build Tools", install, and reboot if necessary.
- 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
- 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'))
- Install
swig with Chocolatey (in PowerShell). choco install -r -y swig
- 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.
- 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
- Use
cd to change into the directory m2crypto was cloned/extracted to.
- 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.)
- Generate the installable files.
python.exe setup.py bdist_wheel bdist_wininst bdist_msi.
- 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.
set PATH=c:\pkg\include\openssl;%PATH%. Windows also usesINCLUDE, so you might alsoset INCLUDE=c:\pkg\include\openssl. That's assumming a header is located atc:\pkg\include\openssl\include\openssl\opensslv.h. Note: I had a problem once with the doubleinclude\openssl. So you might change the directory toc:\pkg\include\openssl-xxx. – Bonitabonitoc:\pkg) and yes @MikeDriscoll, I too would prefer an installer... when it comes back online! – Sabian
