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 qtThe rest of this file assumes that Qt is installed in /usr/local/qt.
|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|
|QT_FONTPATH||optional. A list of directories where Qt can find type1 or true type fonts for print embedding.|
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
If you have some true type or type1 fonts installed in non standard places, you might want to set the QT_FONTPATH environment variable to point to these directories. This is not needed, when all fonts are accessed through local font directories or a local font server, as Qt will automatically scan the fontpath and the font servers configuration file. All directories in the fontpath will need to have a valid fonts.dir file, so Qt can map from X11 font names to the corresponding embeddable font.
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.
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:
makeIf your platform or compiler is not supported, read PORTING. If it is supported but 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.
