Attached code from newer gcc isn't included with my gcc.

Comment 3 Fredrik Höglund 2009-01-08 00:21:17 UTC

SVN commit 907374 by fredrik:

Don't build the SSE2 code when gcc 3.x is used, since it doesn't
support _mm_malloc().

Comment 4 Hasso Tepper 2009-01-31 08:54:58 UTC

I don't think that the committed fix is a correct one. GCC3 supports SSE2 AFAIK, it just doesn't have _mm_malloc/_mm_free. I haven't tested it myself, but judging from the patch FreeBSD ports have been used for a while [1] I think that I'm right :).

PS. Please backport it to the 4.2 branch as well.

Comment 5 Myriam Schweingruber 2012-09-08 12:41:28 UTC

I assume this is still valid for KDE 4.9.x? Please set the version field.

Comment 6 wbrana 2012-09-11 14:09:16 UTC

gcc 3 is obsolete
