Freezing the msl-loadlib package

If you want to use PyInstaller or cx-Freeze to bundle msl-loadlib in a frozen application, the 32-bit server must be added as a data file.

For example, using PyInstaller on Windows you would include an --add-data option

pyinstaller --add-data "..\site-packages\msl\loadlib\server32-windows.exe:."

where you must replace the leading .. prefix with the parent directories to the file (i.e., specify the absolute path to the file). On Linux, replace server32-windows.exe:. with server32-linux:.

If the server is loading a .NET library that was compiled with .NET < 4.0, you must also add the server32-windows.exe.config data file. Otherwise, you do not need to add this config file.

cx-Freeze appears to automatically bundle the 32-bit server (tested with cx-Freeze version 6.14.5) so there may not be anything you need to do. If the server32 executable is not bundled, you can specify the absolute path to the server32 executable as the include_files option for the build_exe command.

You may also wish to refreeze the 32-bit server and add your custom server to your application.
