Bug 208250 – media-plugins/audacious-plugins-1.4.4 doesn't build FLAC support even with "flac" USE flag

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Laurent Bardin 2008-01-30 23:23:11 UTC]

After upgrading to media-sound/audacious-1.4.5 and media-plugins/audacious-plugins-1.4.4 (both from the 1.3 tree), Audacious wouldn't play my FLAC files. The plugin option wouldn't even appear in the Preferences > Modules > Decoders window. Installing media-libs/flac-1.2.1-r1 manually and rebuilding media-plugins/audacious-plugins saved the day.

Reproducible: Always

Steps to Reproduce:
1. merge media-plugins/audacious-plugins with USE="flac" and uninstalled media-libs/flac;
2. even though the configure line contains "--enable-flac", media-libs/flac isn't pulled in. Build log shows "checking for flac >= 1.1.2... no" and carries on;
3. launch audacious and try to play a flac file.

Actual Results:  
The flac file is not played.

Interesting build log sections:

Input Plugins

Expected Results:  
media-libs/flac should be pulled in and merged.

Manually emerging media-libs/flac before media-plugins/audacious-plugins did the trick.

<snip>
checking for flac >= 1.1.2... yes
checking FLAC_CFLAGS... -I/usr/include/FLAC  
checking FLAC_LIBS... -lFLAC -lm

Input Plugins

  Free Lossless Audio Codec (flacng):    yes

The ebuild contains "flac? ( >=media-libs/libvorbis-1.0 )", while it should logically also use media-libs/flac. A change from the 1.3 tree, maybe?

Will post full build log if needed and asked for.

[Comment 1 Laurent Bardin 2008-01-30 23:39:43 UTC]

A quick additional note: my "flac" USE flag was only activated for audacious-plugins, in /etc/portage/package.use.

The behavior should still be the same, unless the user also has the "sndfile" USE flag set, as media-libs/libsndfile will pull in media-libs/flac, enabling it for any ./configure that needs it.

+  21 Feb 2008; Tony Vroon <[e-mail]>
+  audacious-plugins-1.4.4.ebuild, audacious-plugins-1.4.5.ebuild:
+  Add missing libflac dependency, as pointed out by Laurent Bardin
+  <[e-mail]> in bug #208250.

This is now in CVS, and will appear in the portage tree within 2 hours. Looks like I removed too much when I sorted & cleaned the dependency list for 1.4; your bug report is appreciated :)

Thank you for your contribution to Gentoo Linux.
