Hi All, i'm update my MAC OSX from version 10.9 to 10.10.5, and Qt from 5.4 to 5.5
Now compiling my qt project I get a lot of errors:

Hi,

Do you have CONFIG += c++11 in your .pro file ?

xalisonx · S SGaist 16 Feb 2016, 23:57

@SGaist nope

My .pro file:

QT       += core gui network widgets
TARGET = myproject
TEMPLATE = app
CONFIG   -= app_bundle
DESTDIR     =    /Users/myuser/Desktop/root/current/bin_osx

INCLUDEPATH += common imagecommand server
SUBDIRS     += common imagecommand server

QMAKE_CXXFLAGS += -std=c++0x -pthread

The correct way to activate C++11 in your .pro file is to use CONFIG += c++11 that will take care for you of the various platform differences i.e. in your case you should also change the -stdlib parameter which would be OS X specific.

Thanks SGaist, it's works adding c++11!
You have saved my day.

What do you mean exactly with "change the -stdlib parameter"?

SGaist · 9 Aug 2017, 14:16

You're welcome !

Change it to -stdlib=libc++
