Bug 551780 – app-backup/backintime-1.1.4 fails to build due to wrong python version test in ./configure

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Timo Ollech 2015-06-11 13:41:40 UTC]

With the latest version 1.1.4 first I had to add the USE flag python_single_target_python3_3 for backintime to build, as Python 2.7 is still my system default. Now the build fails with the following schizophrenic error message:

Python 3.3.5
Warning: Wrong Python version.
Please make sure Python 3.x is used by adding '--python' or '--python3'.
 * ERROR: app-backup/backintime-1.1.4::gentoo failed (configure phase):
 *   (no error message)
 * 
 * Call stack:
 *     ebuild.sh, line  93:  Called src_configure
 *   environment, line 2817:  Called die
 * The specific snippet of code:
 *       ./configure --python3 --no-fuse-group || die;


Python 3.3.5 qualifies for being Python 3.x in my view... So the test in the configure script must be wrong somehow, but I can't figure out how to fix it.

Reproducible: Always

Created attachment 405244 [details, diff]
A patch that fixes the configure script

I observed the same thing. The reason is that 'python3 --version' outputs the version number to stderr, not stdout, so the grep won't see it. I attached a patch that should fix it (I didn't run the entire emerge, but configure now works).

FYI, this change was included in 1.1.8.
