INSTALLING Qt FOR X11
You may need to be root, depending on the permissions of the directories
where you choose to install Qt.
1. Unpack the archive if you have not done so already:
gunzip qt-x11-2.2.0.tar.gz # uncompress the archive
tar xf qt-x11-2.2.0.tar # unpack it
This creates the directory /usr/local/qt-2.2.0 containing the
files from the main archive.
Rename qt-2.2.0 to qt (or make a symlink):
mv qt-2.2.0 qt
The rest of this file assumes that Qt is installed in /usr/local/qt.
2. Set some environment variables in the file .profile (or .login,
depending on your shell) in your home directory. (Create the
file if it is not there already.)
QTDIR - wherever you installed Qt
PATH - to locate the moc program and other Qt tools
MANPATH - to access the Qt man pages
LD_LIBRARY_PATH - for the shared Qt library
This is done like this:
In .profile (if your shell is bash, ksh, zsh or sh), add the
export QTDIR PATH MANPATH LD_LIBRARY_PATH
In .login (in case your shell is csh or tcsh), add the following lines:
setenv QTDIR /usr/local/qt
setenv PATH $QTDIR/bin:$PATH
setenv MANPATH $QTDIR/man:$MANPATH
setenv LD_LIBRARY_PATH $QTDIR/lib:$LD_LIBRARY_PATH
After you have done this, you will need to login again, or
re-source the profile before continuing, so that at least $QTDIR
is set. The installation will give an error message and not
3. Install your license file. For the free edition, you do not need
a license file. For Professional and Enterprise editions, install
your license file as described in your distribution.
This step compiles the Qt library, and builds the example programs,
the tutorial, and the tools (eg. the Designer).
This will configure the Qt library for your machine. Note that
GIF support is turned off by default. Run ./configure -help
to get a list of configuration options. Read PLATFORMS for a
list of supported platforms.
To create the library and compile all examples and the tutorial:
If your platform or compiler is not supported, read PORTING. If it is
supported but you have problems, see http://www.trolltech.com/platforms/
5. In very few cases you may need to run /sbin/ldconfig or something
similar at this point if you are using shared libraries.
If you have problems running the example programs, e.g. messages like
can't load library 'libqt.so.2'
you probably need to put a reference to the qt library in a
configuration file and run /sbin/ldconfig as root on your system.
And don't forget to set LD_LIBRARY_PATH as explained in 2) above.
6. The online HTML documentation is installed in /usr/local/qt/doc/html/
The main page is /usr/local/qt/doc/html/index.html
The man pages are installed in /usr/local/qt/doc/man/
That's all. Qt is now installed.
