[Paraview] qt5 issues on OSX

[Fabian Wein]

Hello,

I have an up-to-date OS X system (10.11) and try to compile PVSB by myself using the system clang compiler. 
I use psvb v5.1.2 and only enable paraview and qt. I compile with export VERBOSE=1

It is known, that qt4 does not compile any more with clang on OSX.

The standard qt5 version in versions.cmake is 5.4.1and results in a compile error (see below)

Changing qt5 in versions.cmake to the current 5.7.0 requires to remove 
-skip qtquick1 
-skip qtwebkit
from qt5.cmake.

It results in another compile error (see below) which is strange as qt5.7.0 compiles if I just compile the sources (with default configure and the configure from pvsb, see also below). 

According to 
https://forum.qt.io/topic/64255/compile-errors-updating-my-osx-and-qt/6 
one should configure -std=c++11 instead of -std=c++1z which I didn’t manage yet.

With the latest qt 5.6 I made the same observations as with qt 5.7.0.

With qt 5.5.1 ist works.

However I was not able to compile qt 5.5.1 on Linux with gcc 6.1 (but had no issues with 5.7.0 beside the two skips to be removed). So I’ll use 5.5.1 for OSX with clang and 5.7.0 with gcc 6.1 on Linux.

Anyway, psvb doesn’t compile on OS X 10.11 with standard clang but with the proper change in versions.cmake for qt5 it works.
