Problem compiling Qt example from OS X terminal

Your include paths are not set correctly. Can you paste the hello.pro and the hello.cpp here (use the @-Tags or the button to pretty format the code).

The Following is the hello.pro

TEMPLATE = app
TARGET =
DEPENDPATH += .
INCLUDEPATH += .

Input

SOURCES += hello.cpp@

The following is the hello.cpp
@#include <QApplication>
#include <QLabel>

int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QLabel *label = new QLabel("Hello Qt!");
label->show();
return app.exec();
}

Your qmake seems to be setup to create XCode project files (that creates the file hello.xcodeproj). You should try

@
rm -rf hello.xcodeporj
rm Info.plist

qmake -spec macx-g++
@

That removes the XCode project files and creates a normal makefile for you.

Worked perfectly! Thanks so much!

goetz

You're welcome.

Just for curiosity: How did you install Qt? The default mode for qmake is generating a makefile, not an xcode project, as far as I know.

Volker, I've stucked with same problem when ported one of my projects to MacOSX. Qt was installed from package from qt ftp. I think that setting QMAKESPEC will help, but didn't try (always explicitly setted -spec param to qmake).

goetz

Ah, I see. I've always compiled the libs manually, there the default is normal makefiles.

You can change the default: Go to the installation directory of Qt, enter the mkspecs directory and change the symbolic link default to macx-g++, that should work.

DenisKormalev

Volker, yeah, another good way :)

goetz

Once in a while one forgets the -spec switch and gets the wrong proejct files :)

I installed Qt 4.7.0, Qt Creator 2.0.1, and Xcode Developer 3.1.3.

All of them were installed from disk images.

I didn't install any of them manually.
