Bug 559802 – dev-qt/qtcore:5 fails to emerge on ia64 (qatomic_ia64.h:1038:6: error: prototype for ‘bool QBasicAtomicOps<size>::testAndSetRelaxed(T&, T, T)’ does not match any in class ‘QBasicAtomicOps<size>'

Hi,

I know, dev-qt/qtcore:5 isn't keyworded on ia64. I don't know whether it's not keyworded because nobody gave it a try before or because they're known issues on ia64. In case nobody tries it before, here are some errors reported from build.log:

* It seems that gold is used as a linker. But gold isn't available on ia64:

ia64-unknown-linux-gnu-g++: error: unrecognized command line option ‘-fuse-ld=gold'

* Symbolic function binding is disabled. They're probably other architectures beside ia64:

bsymbolic_functions.c:2:2: error: #error "Symbolic function binding on this architecture may be broken, disabling it (see QTBUG-36129)."

* Last but not least, the error that's currently preventing dev-qt/qt-core:5 from emerge successfully:

../../include/QtCore/../../src/corelib/arch/qatomic_ia64.h:1038:6: error: prototype for ‘bool QBasicAtomicOps<size>::testAndSetRelaxed(T&, T, T)’ does not match any in class ‘QBasicAtomicOps<size>’

If it's _expected_ that dev-qt/qt-core:5 doesn't emerge successfully on ia64, just ignore this bug report. Otherwise, tell me how I can help further.

Thanks,

     Émeric

First of all, thanks for trying and for the nice bug report.

IIRC this was caused by improper detection of -fuse-ld=gold support, and was fixed in a later branch... can you try 5.5.0 from the qt overlay?

This is expected. IIRC they disabled it because some signal/slot magic paired with PMF is incompatible with symbolic functions on most arches.

I guess upstream hasn't tried to build on ia64 in a very long time :-/

Well the last error appears to be a genuine upstream bug. What you could do is investigate it, create a patch, and submit it upstream via gerrit (https://codereview.qt-project.org/)

Thanks!

[Comment 8 Michael Palimaka (kensington) 2015-10-16 18:53:13 UTC]

This was accepted upstream. Are we going to backport it?

[Comment 9 Davide Pesavento (RETIRED) 2015-10-16 19:23:00 UTC]

Backport to what? isn't the patch already in 5.5.1?

[Comment 10 Michael Palimaka (kensington) 2015-10-17 13:56:56 UTC]

My mistake, the changeid changed.

[Comment 11 Michael Palimaka (kensington) 2015-10-17 17:55:05 UTC]

Thanks, this is fixed in 5.5.1.

Well, while my patch was indeed accepted/merged upstream, I can tell you for sure that it's _not_ in qtcore-5.5.1 currently in portage tree! Build thus still fails exactly the same.

[Comment 13 Davide Pesavento (RETIRED) 2015-10-19 23:51:57 UTC]

hmm.. apparently your patch was merged *after* 5.5.1 was branched from 5.5 (which happened an unusually long time before the 5.5.1 release).
We can definitely backport then.

[Comment 14 Davide Pesavento (RETIRED) 2015-10-20 01:30:53 UTC]

Done, thanks.

[Comment 15 Émeric Maschino 2015-10-20 20:41:13 UTC]

(In reply to Davide Pesavento from comment #14)
> Done, thanks.

Thanks. BTW, I just got notification from [1] that the fix is present in 5.5.2/5.6.0. I can wait for 5.5.2 to enter portage tree, so don't worry with 5.5.1.
