Created attachment 731287 [details] emerge --info For the development of an iwd client, I woud like to test it against older versions of Python. And even though netifaces-0.11.0.ebuild states PYTHON_COMPAT=( pypy3 python3_{7..10} ) it refused to build for python3.7: # PYTHON_TARGETS="python3_7" emerge netifaces Calculating dependencies - !!! Problem resolving dependencies for dev-python/netifaces ... done! !!! The ebuild selected to satisfy "netifaces" has unmet requirements. - dev-python/netifaces-0.11.0::gentoo USE="" ABI_X86="(64)" PYTHON_TARGETS="(-pypy3) (-python3_10) -python3_8 -python3_9" The following REQUIRED_USE flag constraints are unsatisfied: any-of ( python_targets_pypy3 python_targets_python3_8 python_targets_python3_9 python_targets_python3_10 ) Python3.7 is installed on this system: # which python3.7 /usr/bin/python3.7 For testing purposes I like having mutiple Python versions, and therefore have this in /etc/portage/package.use/python: # cat /etc/portage/package.use/python3.8 */* PYTHON_TARGETS: python2_7 python3_7 python3_8 python3_9 python3_10
Support from the eclasses is gone, I think you'll need to use a virtualenv.
