Kmail and some other KDE packages FTBFS with Qt 5.7.1

[Rik Mills]

FAO Timo etc, on landing new Qt

On Zesty, with staged Qt: https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/1985

amd64 build

kubuntu CI builds of

kmail
parley
kpimtextedit
kidentitymanagement
kdepim-addons
qapt
libkeduvocdocument

fail with linking errors such as the one below:

With Qt 5.6.1 these failure were not present.

Some appear to occur during tests, but others such as the example below occur during the main build

I note that a similar error in compiling QtWebkit on armhf (bug #1653529) was addressed by disabling gold linker for armhf.

For testing purposes, I uploaded a build of qtbase to our CI with amd64 added to nogoldlinker_architectures option.

All the above packages then built without this error.

[Timo Jyrinki (timo-jyrinki)]

I didn't see this on any of Ubuntu Touch reverse dependencies, but it seems it happens.

I've understood the gold linker does not bring much speed benefits anymore these days. Maybe upstream will consider considering making GNU linker the default again at some point.

Meanwhile, I'm building a similar build at https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2348/+packages now - and will copy over to 1985 eventually. That brings the total of non-gold architectures to four (amd64, i386, powerpc, armhf).

There is also at least one Unity 8 bug that needs fixing before the PPA can be published, but otherwise functionality seems ok, autopackagetests seem "ok" (to the extent they usually are) etc.

[Launchpad Janitor (janitor)]
