Bug 662024 – =app-emulation/qemu-2.12.0-r3 USE="-python": fails to build during python update: ERROR: Python not found. Use --python=/path/to/python

• Status: RESOLVED FIXED

build.log

Upgrading to python:3.6 caused a rebuild of app-emulation/qemu. This rebuild failed, since qemu was build before python:3.6 was installed. This happened during an update with parameter --jobs. It builds fine after python:3.6 was installed.

The qemu ebuild only DEPEND on python-2* and only includes the ${PYTHON_DEPS} for static builds with USE="python". So it seems that qemu should DEPEND on python:3.6 or something is wrong with the configure step.

The error is: 

ERROR: Python not found. Use --python=/path/to/python
