Installing Qt for Mac OS X

Step 2: Build the Qt Library

To configure the Qt library for your machine type, run the ./configure script in the package directory.

By default, Qt is configured for installation in the /usr/local/Trolltech/Qt-%VERSION% directory, but this can be changed by using the -prefix option.

 cd /tmp/qt-everywhere-opensource-src-%VERSION%
 ./configure

Type ./configure -help to get a list of all available options.

Note that you will need to specify -universal if you want to build universal binaries, and also supply a path to the -sdk option if your development machine has a PowerPC CPU. By default, Qt is built as a framework, but you can built it as a set of dynamic libraries (dylibs) by specifying the -no-framework option.

Qt can also be configured to be built with debugging symbols. This process is described in detail in the Debugging Techniques document.

To create the library and compile all the demos, examples, tools, and tutorials, type:

 make

If -prefix is outside the build directory, you need to install the library, demos, examples, tools, and tutorials in the appropriate place. To do this, type:

 sudo make -j1 install

This command requires that you have administrator access on your machine.

Note: There is a potential race condition when running make install with multiple jobs. It is best to only run one make job (-j1) for the install.

If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing make confclean before running configure again.

 PATH               - to locate qmake, moc and other Qt tools

 PATH=/usr/local/Trolltech/Qt-%VERSION%/bin:$PATH
 export PATH

 setenv PATH /usr/local/Trolltech/Qt-%VERSION%/bin:$PATH
