This file contains information about building SoQt on Mac OS X.
Building SoQt on Mac OS X should be straightforward. If it isn't, we
consider this a bug, so please let us know and we'll be happy to fix it.
If you install Coin from the binary SDK, please note that you also
have to install the CoinTools.pkg, since the coin-config utility is
needed by SoQt/configure.
SoQt is installed as SoQt.framework by default. For more information
about frameworks, please refer to the README.MACOSX file that comes
Note that we do not support Mac OS 10.0.x. It will probably work just
fine if you compile SoQt yourself, but we don't guarantee that. Please
upgrade at least to 10.1, you will be amazed by the increase in
performance and stability.
Qt/Mac vs. Qt/X11
SoQt is dependent on Trolltech's Qt library. On Mac OS X, you have two options:
1. Use the native Qt/Mac
2. Use X11 and Qt/X11
Qt/Mac is the Mac OS X native implementation of Qt. This will usually
be your first choice, since it does not require any additional
software to be installed, and provides the full Aqua look'n'feel.
Alternatively, you can install Apple's X11 for Mac OS X, and use
Qt/X11, the version of Qt used on all other UNIX systems. You will
find instructions on how to do this below.
Using SoQt together with the X11 Window system
To use SoQt with X11 and Qt/X11, follow these steps:
1. Install X11 for Mac OS X.
X11 for Mac OS X offers a complete X Window System implementation for
running X11-based applications on Mac OS X. It includes the full
X11R6.6 technology including an X11 window server, Quartz window
manager, libraries, and basic utilities such as xterm, and is fully
integrated with Mac OS X.
X11 is not installed by default, but in installer package should be
included with your Mac OS X CDs. (If X11 is installed, you should be
able to launch it via /Applications/Utilities/X11.app. If you do not
have this application, you need to install X11.)
Note that only Apple's X11 is supported. (XDarwin, the X installation
through fink, or anything else will probably not work.)
2. Build and install the X11 version of Coin.
In order to use X11 instead of Quartz/Aqua, use the --enable-darwin-x11
configure option. You need to build both Coin and SoQt using this option.
$ /path/to/Coin/configure --enable-darwin-x11
$ make && sudo make install
3. Install Qt/X11.
SoQt depends on Qt/X11. It does not really matter how you install Qt,
but I suggest you use fink or DarwinPorts.
4. Install SoQt.
Again, use the --enable-darwin-x11 configure option like you did for Coin.
$ /path/to/SoQt/configure --enable-darwin-x11
$ make && sudo make install
That should be all.
Common problems (and solutions)
Problems with older versions of Qt/Mac
The first Qt/Mac releases contained a number of serious bugs that also
affect SoQt. If you encounter strange behaviour, it might very well be
that upgrading to the latest version of Qt/Mac will fix the problem.
Undefined QTDIR in bash
Note that if you use bash as your default shell, you must make it read
your .bashrc file - it does not do that by default.
So if you have defined QTDIR in your ~/.bashrc, and still configure
fails with because it cannot find Qt, check if QTDIR is actually set:
% echo $QTDIR
If this is empty, you have a problem. Make sure you are actually using
% echo $SHELL
... and that the content of your ~/.bashrc looks reasonable, something
If you are using bash, and your .bashrc is correct, but QTDIR doesn't
get set, you have to make bash read your .bashrc file. To do that,
create a file called ~/.bash_profile with the following content:
if [ -f ~/.bashrc ]; then
Open a new Terminal window - things should work now. If you still have
problems, something else is wrong. In that case, feel free to let us know.
