QtOpengl conflict with Opengl framwork on mac

supersuraccoon

I am trying to merge cocos2d-x 3.12 and Qt 5.7 together and was keep getting the conflict error message when linking:

In file included from Qt5.7.0/5.7/clang_64/lib/QtOpenGL.framework/Headers/QGLWidget:1:

I tried to remove the Opengl Framework in .pro file like this :

QT       += core gui opengl

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = QtApplication
TEMPLATE = app

#INCLUDEPATH += /usr/local/include
#LIBS += -L/usr/local/lib/ -lGLEW
LIBS += -L/usr/local/lib/ -lz
LIBS += -L/usr/local/lib/ -lcurl

LIBS    += -framework Cocoa
LIBS    += -framework Foundation
LIBS    += -framework OpenAL
LIBS    += -framework IOKit
LIBS    += -framework CoreVideo
LIBS    += -framework OpenGL

But it was not working, still the same error.

Any advice will be appreciated, thanks :)

Hi,

Looks rather like cocos2d-x is doing something funky here. You should comment that line since glDepthRangef is provided by the current OS X SDK.

@SGaist Thanks for your reply, I commented out the 2 lines in one file and now it compiled and linked fine.

I am able to run the app now but was having some problems I thought might be related to this modification ?

I have posted it here, may be you will be have time to have a look:
