Question

我正在尝试将cocos2d-x 3.12和Qt 5.7合并在一起，并在链接时不断收到冲突错误消息：

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

GLAPI void APIENTRY glDepthRange (GLclampd near, GLclampd far);

我试图在.pro文件中删除Opengl Framework，如下所示：

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

但它没有用，仍然是同样的错误。

任何建议都将不胜感激，谢谢：）

我认为这个错误是由于Qt的政策覆盖了glew.h或GL.h提供的与OpenGL相关的宏定义。其他人试图解决这个问题并遇到类似的问题（例如GLEW and Qt5 redefinition of headers）。让我这样做的解决方法是避免在同一个文件中包含GL.h / glew.h和任何与OpenGL相关的Qt头。

QtOpengl与mac
