Bug 382165 – media-libs/vigra-1.7.1: Does not work with python 3

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Marko D 2011-09-07 18:31:26 UTC]

If the active python is set to python 3.2, cmake will fail with the message:

    from distutils.sysconfig import *; print get_python_lib(1)

If the active python installation is set to python 2 (python 2.7) cmake will build successfully.

Reproducible: Always

That is quite possible, yet i can't use python eclass due to eapi reasons -> CANTFIX.

Just use normal py2 as system python like everyone else for now.

[Comment 2 gentoo 2011-10-06 14:15:46 UTC]

Hi! Same problem here. Can you please link this bug to the bug relating to eclass dependency mentioned in comment #1? Thanks!

[Comment 3 Sergey S. Starikoff 2011-10-08 07:13:27 UTC]

The same issue with (3.1) python slot (3.1.3-r1).
media-libs/vigra-1.7.1 seems to be incompatible with not only python-3.2, but python3.

[Comment 4 Pacho Ramos 2011-10-17 21:29:11 UTC]

I think python.eclass can now use eapi4, would be nice to get this solved :)

[Comment 5 Tomáš Chvátal (RETIRED) 2011-10-18 07:30:17 UTC]

Well you could've done it.

Anyway, eclass added.

[Comment 6 Pacho Ramos 2011-10-18 09:36:43 UTC]

Will do next time (I preferred to comment for now as the package is not maintained by me and maybe you wouldn't allow me to commit that changes :))

[Comment 7 gentoo 2011-10-25 17:54:59 UTC]

Please mark 1.7.1-r1 as stable on amd64 because the currently stable version, 1.7.1, doesn't compile due to this bug. Thanks! (And thanks for the bug fixing, too!)
