atlas uses a different default gcc than other ports

[jmroot (Joshua Root)]

As per #20103, math and science ports should all try to use the same gcc version by default. Recent changes to atlas made it use gcc44, while everything else is currently using gcc43. It may well be time to change to 4.4, but everything should do it at once.

atlas compiled with gcc43 does not work on newest i5/i7 processors. That's why we moved forward.

Could the new gcc also cause hard lockups? I've had my machine freeze four times in a row trying to build it, and there are some crash logs for "xprobe_gas_x8632" and xprobe_3dnow. Sadly, no build log.

[Veence (Vincent)]

the crashes in xprobe_gas and xprobe_3dnow are normal: the program tests some instructions and a crash indicate a wrong guess (wrong architecture). Where exactly does the freeze happen?

[lists.pascal.juergens@…]

I don't know where, since all the logs were dead after the reboot. Would piping them to a non-encrypted folder work, or does the file get cleaned up by HFS' journal?

Try building with the -v option. If the machine freezes, you should have ample time to read out what Terminal says... :) Viel Glück!

Thanks a lot. I just did that, and horribly enough, the build went through. I'll re-build once again, but unless that turns anything up, I'll just write it off as a heat issue or something. Thanks for the help!

No problem. Glad you got satisfaction eventually (not like in the famous song) :). Bis dann!

Has duplicate #25273.

[jmroot (Joshua Root)]

Since there has been nothing done about this in 2 weeks, I fixed it myself in r68906.

[jmroot (Joshua Root)]

And we're right back here after r71201.
