Description Lauri Kasanen 2013-12-14 14:13:02 UTC

My GCC does not support the -msse4.1 switch. It should be detected in configure before trying to use it, for example with the AX_CHECK_COMPILE_FLAG macro from the autoconf archive.

This was added in commit 6f2e81ce4cc by Matt Turner.

-msse4.1 has existed in gcc since 4.3. 4.3 was released five and a half years ago. Why are you using something older than that?

Sounds like you've got a good idea how to solve it. Send a patch and I'll review it.

Comment 2 Lauri Kasanen 2013-12-16 09:04:20 UTC

Originally to be compatible with the BSDs and Mac, now it's just convenient for building binaries that run on any distro (with newer GCCs requiring newer libstdc++).

I think it would be fair for you to fix it since you broke it ;) but sure, I'll provide a patch this week.

Committed your patch. Thanks
