Updating Glibc 2.13-r4 > nptl conf > C cleanup handling

[Matias Jose Seco]

Greetings,
previously i was attempting to perform a glibc update from 2.12.2 to 2.13-r4, but it failed:
during GLIBC configuration for nptl, it stopped when checking "C cleanup handling" because "compiler must support it"

GCC version is 4.5.3-r1.
I've founded some solutions but as long as they didn't where for gentoo specifically, i didn't know which consequences could trigger (as long as i'm not expert too)

Regards, Matias

Please post the output of emerge --info, the config.log from the failed build, and links to the solutions you want evaluated.

We need config.log, not build.log. The config.log will show exactly what test was run and the way in which it failed. The build.log describes the test, but does not tell us how it failed.

This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

This appears to be a bug in the configure script. They assume that they can pass -Werror, but they use code which causes a warning, which then becomes fatal when they add -Werror. As a workaround, you can remove -Wall -Wextra from your CFLAGS, so that their bad code does not generate a warning.

[Matias Jose Seco]

Ok

Do you want i also open a ticket on Bugzilla for the issue?
If you think isn't necessary, i'll stay happy anyway

NOTE: But, as i see, Gentoo do not suggest to set per-package cflags, and as long as i would like to use
those flags system wide for my system-debug porpouse, how i could help resolving it ?

Thanks again!!

Matias

Most developers do not read the forum in enough detail to see this thread. If you want a change made, then please file a bug. However, beware that the upstream glibc maintainers are notoriously unfriendly and uncooperative. Some of the Gentoo maintainers that deal with glibc seem to have picked up that attitude, too.

[Matias Jose Seco]

Going towards light

I'll try the resolution way

Profound appreciation for the cooperation , if you think i could add more useful informations on the bug thread, i would add it as soon

Thanks again, Matias

Hu missed a point: the check in question works only by using '-Werror', otherwise gcc would only generate a warning.

[Matias Jose Seco]

So as long as i can't use '-Wall -Wextra',
could i set them for a specific package to debug it, only if needed?

(The problem is that Gentoo Cflag's manual do not advice to use per-package cflags, but if
the flags are '-Wall -Wextra' for debugging only, i think it would not create problems)

That was something that was commented upon a month or two ago (well, less than six) on wine-devel.
It was fix in the upstream git, but:

• it's not out of the repo yet
• see the commit's comment

This topic's original problem goes from the opposite direction, but reaches the same point.
