Qt wymaga wsparcia C++ 11”zrobić błąd

Question

Próbowałem skompilować najnowszy kafelki z kodu źródłowego zgodnie z instrukcjami w README.md

Moje środowisko pracy.

kod źródłowy kaflowy: kafelki-0,16. 1

Mac OS: 10.11.1

Xcode 7.1

QMake: 3,0

Qt: 5.7.0

Jabłko LLVM: 7.0.0

Ale marka nie powiodło się z powodu następującego błędu:

Po robi rozeznanie, starałem się dodać linię do CONFIG+= c++11 plik tiled.pro a następnie dokonać czystej, qmake, należy jednak nadal mam ten sam błąd ......

tiled.pro:

# Check the Qt version. If QT_VERSION is not set, it is probably Qt 3. 
isEmpty(QT_VERSION) { 
    error("QT_VERSION not defined. Tiled does not work with Qt 3.") 
} 

include(tiled.pri) 

!minQtVersion(5, 1, 0) { 
    message("Cannot build Tiled with Qt version $${QT_VERSION}") 
    error("Use at least Qt 5.1.0.") 
} 

TEMPLATE = subdirs 
CONFIG += ordered 
CONFIG += c++11 

SUBDIRS = src translations 

Nie jestem pewien, co tu jest nie tak.

Wszelkie porady będą mile widziane, dzięki :)

UPDATE:

Tried

QMAKE_CXXFLAGS += -std=c++11 

i

QMAKE_CXXFLAGS += -std=c++0x 

Nadal masz ten sam błąd ......

Pomyślałem, że może to być w C++ skompilować użyć polecenia make, tutaj jest kilka informacji:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -c `python-config --cflags` -O2 -std=gnu++11 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk -mmacosx-version-min=10.8 -fvisibility=hidden -fvisibility-inlines-hidden -Wall -W -fPIC -DPYTHON_LIBRARY -DQT_NO_DEBUG -DQT_PLUGIN -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I. -I../../libtiled -I/Users/supersuraccoon/Qt5.7.0/5.7/clang_64/lib/QtWidgets.framework/Headers -I/Users/supersuraccoon/Qt5.7.0/5.7/clang_64/lib/QtGui.framework/Headers -I/Users/supersuraccoon/Qt5.7.0/5.7/clang_64/lib/QtCore.framework/Headers -I. -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/OpenGL.framework/Headers -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/System/Library/Frameworks/AGL.framework/Headers -I/Users/supersuraccoon/Qt5.7.0/5.7/clang_64/mkspecs/macx-clang -F/Users/supersuraccoon/Qt5.7.0/5.7/clang_64/lib -o pythonplugin.o pythonplugin.cpp 

Answer 1

miałem podobny problem budowania poppler z owijarki Qt i dostał ten sam błąd: „Qt wymaga C++ 11 wsparcie".

Moja konfiguracja to:

Mac OS: 10.11.5 
Xcode : 7.3.1 
QMake: 3.0 
Qt: 5.7.0 
Apple LLVM: 7.3.0 

Ja tylko:

export CXXFLAGS=-std=c++11 
./configure 
make 

i to działało.

Answer 2

Wiem, że minęło trochę czasu. Jak w końcu rozwiązać ten problem dodając CMakeLists.txt następujący wiersz tuż po project(MyProject):

add_compile_options(-std=c++11) 

To mówi do cmake, aby utworzyć Makefile że użyje C++ 11 rozwiązywania problemów.
