I forgot about 2 other types of changes:
- Shebangs in installed scripts should be correct. If build system installs
scripts
with too generic shebangs (e.g. '#!/usr/bin/python'), then you can use
python_convert_shebangs() to convert shebangs.
Example:
src_install() {
...
python_convert_shebangs -r 2 "${D}usr/bin"
}
(Please note that wrapper scripts generated by
python_generate_wrapper_scripts() work
with all versions of Python from 2.4 to 3.2, so shebangs in these scripts do
not need
any changes.)
- Some deprecated functions (python_version(), distutils_python_version()) and
variables
(${python}, ${PYVER} etc.) should not be used.
Documentation [1] has been updated.
I will start filing bugs maybe in this week.
