Build fails when byte-compiling is disabled

Reported by: nero37 Owned by: somebody

Component: packaging Version: 1.6.0

Launchpad Bug:


I have written a gentoo ebuild to build and install tahoe on gentoo systems. In the latest version of python used in gentoo byte-compiling .py files to .pyc/.pyo has been disabled by default, as this functionality is automatically provided by the portage package manager itself when a python package is being installed.

Tahoe now fails to build, for example when building tahoe-1.6.1 with the follow;

python -B setup.py build    
Not found: tahoe-deps
Not found: ../tahoe-deps
warning: build_py: byte-compiling is disabled, skipping.
warning: install_lib: byte-compiling is disabled, skipping.

Thank you for the bug report. This is technically an issue in distutils, but some project (either the Tahoe-LAFS, distutils, setuptools, or distribute projects) need to figure out a work-around. The next step is to open a ticket against distutils on their tracker: http://bugs.python.org/ Please link to this ticket from that one.

P.S. I'm excited that you've written an ebuild for Tahoe-LAFS! There are (at least) two more steps to making Tahoe-LAFS be fully supported on Gentoo:

  1. Set up a buildbot: the How To Contribute A Buildbot page
  2. Get your ebuild included in the standard http://packages.gentoo.org .

Having a Gentoo buildbot would enable us to know whether changes we make have introduced a regression on Gentoo. If someone contributes a Gentoo buildbot and it proves itself to be a stable build machine then we will promote it to Supported Platform status. Being a Supported Platform means that we know the current version works on that platform, and we try not to break it with new improvements.

The next step is for someone to open a ticket against distutils, which is the real culprit here, and link that ticket this Tahoe-LAFS ticket and to the Gentoo ticket. Start here: http://bugs.python.org/ Thanks!
