Bug 441884 – media-libs/libvisual-0.4.0-r2 enables threads unconditionally

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Alexander E. Patrakov 2012-11-05 15:20:07 UTC]

To reproduce, please emerge media-libs/libvisual-0.4.0-r2 with USE="nls -debug -static-libs -threads". Result: the configure script says that threads are enabled, see below. Please either fix this, or remove the "threads" USE flag so that the ebuild does not pretend that there is a way or a use case to disable threads.

Reproducible: Always

[Comment 1 Jeroen Roovers (RETIRED) 2012-11-05 18:58:43 UTC]

Actually the ebuild does the right thing - it's probably the configure script that has the automagic which we should fix.

[Comment 2 Sebastian Pipping 2022-11-20 16:21:26 UTC]

I believe this has been fixed since -r3 where patch libvisual-0.4.0-cond.patch [1] was first introduced.  When compiling locally unlike with -r2 in the report the configure output no longer reads…

…but…

> checking whether to enable thread support... checking thread related libraries... 

…on a single line.  I'm therefore closing this issue as fixed, please re-open as needed.
