Bug 296406 – media-sound/pavucontrol-0.9.4 and media-sound/paprefs-0.9.6 does not compile

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description G. Náray 2009-12-10 14:32:05 UTC]

media-sound/pavucontrol-0.9.4 and media-sound/paprefs-0.9.6 does not compile with dev-libs/libsigc++-2.0.18

Both complained about declaration error, see below. I thought it was the libsigc++ which is too old for them, and updated to 2.... and both compiled.

Reproducible: Always

Steps to Reproduce:
1. emerge paprefs pavucontrol
2.
3.

Actual Results:  
Packages do not compile

Expected Results:  
Packages should compile

Another similar errors follow, then compiling and emerging stops.

Oops, i forgot to write the exact version of libsigc++ which i use now. Updated libsigc++ on this linux is 2.2.3.

[Comment 2 Samuli Suominen (RETIRED) 2009-12-10 18:02:46 UTC]

You should keep your system up-to-date of problems like these will come up... as 2.0 isn't even in Portage.

That said, bumped the deps in both.

[Comment 3 Rafał Mużyło 2009-12-10 20:17:14 UTC]

Well, there's a little catch about it -
IIRC, the problem lies NOT in those apps,
but in a construct in old libsigc++ that recent gcc rejects.
