@Alien Bob: I was wondering how your package worked and not home built ones. At first, I concidered that maybe you had some special CFLAGS in your environment, but that seemed far fetched. I read your slackbuild, and could not find a major difference that told me: "Ah, this is where he fixes the issue!" Thanks for your input and insight.

Cheers,
John

EDIT: rereading this now, it sounds like I am asking a question, but it is just me having an "aha" moment about the difference it made (re: resulting in usable binaries) that you compiled with gcc-4.7.

Check your build log (you kept a log did you?) and find out if a x264 tarball was downloaded before the compilation started.

Eric

Yes, I am sure the newer tarball was used. I removed the old one, the new one was downloaded, extracted and then used. No, I don't have a log. I am still getting the hang of this stuff so I am kinda disorganized.

I applied the diff you posted earlier on (that changes the version and the download URL of the x264 source tarball) and ran a build. This is what I find in the log file:

... meaning your newer x264 source is never used, and the handbrake Makefile still downloads the version it has hardcoded.
It is always a good idea to log your compilation process, or even the output of any long-running process which fills more than one screen.

Eric

Oh, my mistake then. I apologize.

if feel like testing it, now that I know the cause (thanks Eric!) I created a patch to apply to the Slackbuild on SBo: it updates x264 to the latest snapshot tarball

@ponce: I've tested your patch and it works good for me.
