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:
cd /usr/local
gunzip qt-x11-3.0.3.tar.gz # uncompress the archive
tar xf qt-x11-3.0.3.tar # unpack it
This creates the directory /usr/local/qt-3.0.3 containing the
files from the main archive.
Rename qt-3.0.3 to qt (or make a symlink):
mv qt-3.0.3 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 - the directory in which you're building 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
following lines:
QTDIR=/usr/local/qt
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/doc/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH
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 $QTDIR/doc/man:$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
and $PATH is set. The installation will give an error message and
not proceed otherwise.
On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.
3. Install your license file as $HOME/.qt-license.
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.
4. Building.
This step compiles the Qt library, and builds the example programs,
the tutorial, and the tools (eg. the Designer).
Type:
./configure
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:
make
If your platform or compiler is not supported, please contact us at
qt-bugs@trolltech.com so that we can assist you. If it is supported
but you have problems, see http://www.trolltech.com/platforms/
At this point you have binaries created in $QTDIR (eg. $QTDIR/lib/
contains libqt.so). If, however, you would like to have your Qt
installed in a non-local installation you can run configure with
options splitting Qt into different areas for example:
./configure -libdir /usr/local/lib -bindir /usr/local/bin -headerdir /usr/local/include/qt
Then after a successfull make you can:
make install
This will install Qt onto your machine, with these destination options
you will able to segment Qt into different places on your system
(please see ./configure -help for the install option section for more
help). If you choose to install Qt like this, remember you must set
your LD_LIBRARY_PATH to match your -libdir and your QTDIR to your
-headerdir (as described in 2 above).
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.3'
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.
