I get the following when trying to build a project on mac in qtcreator:
In file included from src/main.cpp:4:
In file included from /Users/d/Qt/5.3/clang_64/lib/QtGui.framework/Headers/QGuiApplication:1:
In file included from /Users/d/Qt/5.3/clang_64/lib/QtGui.framework/Versions/5/Headers/qguiapplication.h:47:
/Users/d/Qt/5.3/clang_64/lib/QtGui.framework/Headers/qinputmethod.h:90:5: error: unknown type name 'QLocale'
QLocale locale() const;
^
This is my main.cpp:
/****************************************************************************
basic OpenGL demo modified from http://qt-project.org/doc/qt-5.0/qtgui/openglwindow.html
****************************************************************************/
#include <QtGui/QGuiApplication>
#include <iostream>
#include "NGLScene.h"
int main(int argc, char **argv)
{
QGuiApplication app(argc, argv);
// create an OpenGL format specifier
QSurfaceFormat format;
// set the number of samples for multisampling
// will need to enable glEnable(GL_MULTISAMPLE); once we have a context
format.setSamples(4);
#if defined( DARWIN)
// at present mac osx Mountain Lion only supports GL3.2
// the new mavericks will have GL 4.x so can change
format.setMajorVersion(3);
format.setMinorVersion(2);
#else
// with luck we have the latest GL version so set to this
format.setMajorVersion(4);
format.setMinorVersion(5);
#endif
// now we are going to set to CoreProfile OpenGL so we can't use and old Immediate mode GL
format.setProfile(QSurfaceFormat::CoreProfile);
// now set the depth buffer to 24 bits
format.setDepthBufferSize(24);
// now we are going to create our scene window
NGLScene window;
// and set the OpenGL format
window.setFormat(format);
// we can now query the version to see if it worked
std::cout<<"Profile is "<<format.majorVersion()<<" "<<format.minorVersion()<<"\n";
// set the window size
window.resize(1024, 720);
// and finally show
window.show();
return app.exec();
}
Weird thing is the line 4 from main.cpp is just “#include < QtGui/QGuiApplication >” so everything else is just coming from Qt??
Qt Creator was installed using the qtcreator mac package. And Qt was installed from source using the instructions here: http://qt-project.org/doc/qt-5/macosx-building.html
Thanks for the syntax example… her is the .pro file:
