QGIS compilation fails only on Wily

[Luigi Pirelli]

As stated in this pull request, seems that QGIS compilation fail only under Wily due to some problem in the Ubuntu compilation stack

https://github.com/qgis/QGIS/pull/2587

this happen only uçon Wily (15.10) and notin other Ubuntu versions or other distribution like Debian.

only wily/amd64 is affected - wily/i386 works fine, as do precise, trusty, vivid and Debian jessie, stretch and unstable.

[Jürgen E. Fischer (jef-norbit)]

 but it's unclear if the bug is in cmake, make or some other part of the toolchain.

Brian: Are you positive this is a qgis problem? As said it only appears on wily/amd64 and it doesn't even apply to qgis 2.8 (which builds fine even on wily/amd64). I think it's related to automoc - so something in the conjunction of cmake and Qt - hence the unspecific assignment to "ubuntu"

Can you post a buildlog where compilation fails?

I suppose this is actually the same bug which we had in debian testing:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=806324#74

"
 The problem is just that libQtUiTools.a has been built with the
 binutils from unstable, which introduce new relocation types. The .o
 object files (and thus static libraries) generated by binutils from
 unstable therefore can't be processed by the one from testing.

Hi Johan

I'll provide buildlog soon... please let me know if it's enough the stdout of the QGIS build process of do you need more?

[Jürgen E. Fischer (jef-norbit)]

build log of wily-amd64 from the master nightly.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Jürgen E. Fischer (jef-norbit)]

Downgrading to vivid's cmake helps, while upgrading to xenial's cmake doesn't.

[Jürgen E. Fischer (jef-norbit)]

Now it also affects i386.

Hi, can you please try xenial cmake again? we bringed 3.5.1 a few minutes ago.

[Jürgen E. Fischer (jef-norbit)]

it builds fine with xenial's cmake.
