Bug 47622 – wmix-3.0-r1 fails (gcc 3.3.3, linux-headers-2.6.4)

• Status: RESOLVED UPSTREAM
• Product: Gentoo Linux

I get the following error:

I do not know if this is the fault of gcc (--version gives "gcc (GCC) 3.3.3 20040217 (Gentoo Linux 3.3.3, propolice-3.3-7)") or that I have linux-headers-2.6.4 installed.  However, the following patch makes it work:

Looks to me like wmix-3.1 does not exhibit the same problem.  Anyone else agree?

[Comment 3 Michele Noberasco (RETIRED) 2004-07-16 17:03:01 UTC]

Definitely... I'm removing the old 3.0 ebuild in favour of 3.1...
