You may need to be root, depending on the permissions of the directories where you choose to install Qt.
cd /usr/local gunzip qt-x11-version.tar.gz # uncompress the archive tar xf qt-x11-version.tar # unpack it
This creates the directory /usr/local/qt-version containing the files from the main archive.
Rename qt-version to qt (or make a symlink):
mv qt-version qt
The rest of this file assumes that Qt is installed in /usr/local/qt.
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=$QTDIR/man:$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 $QTDIR/man:$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 proceed otherwise.
On AIX set LIBPATH and on HP-UX set SHLIB_PATH instead of LD_LIBRARY_PATH.
Note that the SGI MIPSpro o32 and Sun WorkShop 5.0 targets are no longer supported as of Qt 3.3.
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:
makeIf you have problems, see http://www.trolltech.com/platforms/.
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.
You're done. Qt is now installed.
