Comment 1 caulier.gilles 2017-01-22 17:08:56 UTC 
I just rechecked and same code compile fine with KConfig 5.29.

So, it's not a compiler problem.

I suspect a change in ECM 5.30 which introduce some wrong compiler options under MacOS.
Comment 2 caulier.gilles 2017-01-22 17:10:22 UTC 
Switch from Apple Clang to GCC 5.4 provided by Macports do not change anything. The compilation is broken at the same place...
Comment 3 caulier.gilles 2017-01-22 17:21:49 UTC 
This is the compilation trace from 5.29 and 5.30 with Apple Clang compiler :

Comment 4 caulier.gilles 2017-01-22 17:31:16 UTC 
Comparing compiler option passed between 5.29 and 5.30, this options have been dropped :

-std=c++0x 
-fno-exceptions
-Wall
-Wextra
-Wcast-align
-Wchar-subscripts
-Wformat-security 
-Wno-long-long
-Wpointer-arith
-Wundef
-Wnon-virtual-dtor
-Woverloaded-virtual 
-Werror=return-type
-pedantic
-Wno-gnu-zero-variadic-macro-arguments

Why ?
Comment 5 caulier.gilles 2017-01-23 16:22:15 UTC 
The problem is exactly the same for MacOS Sierra last version 10.10.2. LAst XCode is installed and KConfig do not compile for same reasons:

Please fix compilation rules for whole KF5 under MacOS. This must be compilable as before with KF5 5.29.

Comment 6 Matthew Dawson 2017-02-04 08:34:52 UTC 
Re-assigning to ECM as it appears to be caused by a change there.  I suspect https://phabricator.kde.org/D4363 may have caused it, but I'm not sure.
Comment 7 caulier.gilles 2017-02-04 10:07:07 UTC 
Ok thanks for the feedback.

I can test quickly a patch if necessary, or with ECM from git/master. Let's me hear...

Comment 8 caulier.gilles 2017-02-21 07:55:12 UTC 
Same problem using current XCode compiler under MAcOS Sierra 10.12.3 and KF5 5.31.
