Qt issues on mac osx 9

sealth

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:

@

This specifies the exe name

TARGET=SimpleNGL

where to put the .o files

OBJECTS_DIR=obj

core Qt Libs to use add more here if needed.

QT+=gui opengl core

as I want to support 4.8 and 5 this will set a flag for some of the mac stuff

mainly in the types.h file for the setMacVisual which is native in Qt5

isEqual(QT_MAJOR_VERSION, 5) {
cache()
DEFINES +=QT5BUILD
}
QMAKE_MACOSX_DEPLOYMENT_TARGET=10.9

where to put moc auto generated files

MOC_DIR=moc

on a mac we don't create a .app bundle file ( for ease of multiplatform use)

CONFIG-=app_bundle

Auto include all .cpp files in the project src directory (can specifiy individually if required)

SOURCES+= $$PWD/src/*.cpp

same for the .h files

HEADERS+= $$PWD/include/*.h

and add the include dir into the search path for Qt and make

INCLUDEPATH +=./include
INCLUDEPATH += /opt/local/include

where our exe is going to live (root of project)

DESTDIR=./

add the glsl shader files

OTHER_FILES+= shaders/*.glsl
README.md

were are going to default to a console app

CONFIG += console

note each command you add needs a ; as it will be run as a single line

first check if we are shadow building or not easiest way is to check out against current

!equals(PWD, $${OUT_PWD}){
copydata.commands = echo "creating destination dirs" ;

now make a dir

copydata.commands += mkdir -p $$OUT_PWD/shaders ;
copydata.commands += echo "copying files" ;

then copy the files

copydata.commands += $(COPY_DIR) $$PWD/shaders/* $$OUT_PWD/shaders/ ;

now make sure the first target is built before copy

first.depends = $(first) copydata
export(first.depends)
export(copydata.commands)

now add it as an extra target

QMAKE_EXTRA_TARGETS += first copydata
}

use this to suppress some warning from boost

QMAKE_CXXFLAGS_WARN_ON += "-Wno-unused-parameter"

basic compiler flags (not all appropriate for all platforms)

QMAKE_CXXFLAGS+= -msse -msse2 -msse3
macx:QMAKE_CXXFLAGS+= -arch x86_64
macx:INCLUDEPATH+=/usr/local/include/
linux-g++:QMAKE_CXXFLAGS += -march=native
linux-g++-64:QMAKE_CXXFLAGS += -march=native

define the _DEBUG flag for the graphics lib

DEFINES +=NGL_DEBUG

unix:LIBS += -L/usr/local/lib

add the ngl lib

unix:LIBS += -L/$(HOME)/NGL/lib -l NGL

now if we are under unix and not on a Mac (i.e. linux)

linux-{
linux-:QMAKE_CXXFLAGS += -march=native
DEFINES += LINUX
}
DEPENDPATH+=include

if we are on a mac define DARWIN

macx:DEFINES += DARWIN
macx:LIBS += -L/opt/local/LIBS
macx:LIBS += -lboost_system-mt -lboost_filesystem-mt

this is where to look for includes

INCLUDEPATH += $$(HOME)/NGL/include/

win32: {
PRE_TARGETDEPS+=C:/NGL/lib/NGL.lib
INCLUDEPATH+=-I c:/boost
DEFINES+=GL42
DEFINES += WIN32
DEFINES+=_WIN32
DEFINES+=_USE_MATH_DEFINES
LIBS += -LC:/NGL/lib/ -lNGL
DEFINES+=NO_DLL
}

Hi and welcome to devnet,

Are you using a pro file to manage your project ? If so can you post it ?

sealth

I've edited the original to include the .pro.... actually the project and the associated library can be downloaded here:

http://nccastaff.bournemouth.ac.uk/jmacey/GraphicsLib/index.html

http://nccastaff.bournemouth.ac.uk/jmacey/GraphicsLib/Demos/index.html

SGaist

Are you saying that it happens when your build that library ? Or just when trying to use ?

sealth

I'm using the library - it's been built already. I know that it works I have class mates who are using it ok - this is an issue with qt on my machine.

here is the compilation output:
