[New-bugs-announce] [issue37247] swap distutils build_ext and build_py commands to allow proper SWIG extension installation

[Jeroen van den Hout]

New submission from Jeroen van den Hout <jlvandenhout at gmail.com>:

Currently when building an extension which lists a SWIG interface (.i) file as a source file, SWIG creates the files correctly in the build_ext command. Unfortunately this command is run after the build_py command, so the python files (.py) created in the build_ext command are never copied to the installation.
To fix this, swap build_ext and build_py commands in the sub_commands attribute of the build command.
