Bug 541420 – dev-lang/python3* cross-compiling: configure error: set ac_cv_file__dev_ptmx to yes/no in your CONFIG_SITE file when cross compiling

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Alexey Kharlamov 2015-02-26 12:49:32 UTC]

Reproducable: on python3.3 and python3.4

The bug is similar to #362945

For the solution it has to be enough to add these lines to 3.3 and 3.4 ebuilds:

  export ac_cv_file__dev_ptmx=yes
  export ac_cv_file__dev_ptc=yes

But I do not know if there are some gentoo targets that needs 'no'. Anyway, without this fix python will not configure.

Log:

checking for /dev/ptmx... not set
configure: error: set ac_cv_file__dev_ptmx to yes/no in your CONFIG_SITE file when cross compiling

I'm not sure if this really belongs in the python ebuild, or in the config.site installed by crossdev. Thoughts?

i fixed this in crossdev already for Chromium OS:

not that python cross-compiling even works anymore even with that fix

It was working the last time I messed with it. Please file bug(s) or fixes if it is broken; I will certainly make an effort to fix it.
