[[scanpypi]]
==== Generating a +python-package+ from a PyPI repository
If the Python package for which you would like to create a Buildroot
package is available on PyPI, you may want to use the +scanpypi+ tool
located in +support/scripts+ to automate the process.
You can find the list of existing PyPI packages
https://pypi.python.org[here].
+scanpypi+ requires Python's +setuptools+ package to be installed on
your host.
When at the root of your buildroot directory just do :
-----------------------
./support/script/scanpypi foo bar -o package
-----------------------
This will generate packages +python-foo+ and +python-bar+ in the package
folder if they exist on https://pypi.python.org.
Find the +external python modules+ menu and insert your package inside.
Keep in mind that the items inside a menu should be in alphabetical order.
Please keep in mind that you'll most likely have to manually check the
package for any mistakes as there are things that cannot be guessed by
the generator (e.g. dependencies on any of the python core modules
such as BR2_PACKAGE_PYTHON_ZLIB). Also, please take note that the
license and license files are guessed and must be checked. You also
need to manually add the package to the +package/Config.in+ file.
If your Buildroot package is not in the official Buildroot tree but in
a +BR2_EXTERNAL+ tree, use the -o flag as follows:
-----------------------
./support/script/scanpypi foo bar -o other_package_dir
-----------------------
This will generate packages +python-foo+ and +python-bar+ in the
+other_package_directory+ instead of +package+.
Option +-h+ will list the available options:
-----------------------
./support/script/scanpypi -h
-----------------------
