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.</p><p>    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.</p><li> 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.</p><li> Building.<p>    This step compiles the Qt library, and builds the example programs,    the tutorial, and the tools (eg. the Designer).<p>    Type:<pre>        ./configure</pre><p>    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.<p>    To create the library and compile all examples and the tutorial:<pre>        make</pre>    If your platform or compiler is not supported, read PORTING.  If it is    supported but you have problems, see <a href=http://www.trolltech.com/platforms/>http://www.trolltech.com/platforms/</a></p><li> In very few cases you may need to run /sbin/ldconfig or something    similar at this point if you are using shared libraries.<p>    If you have problems running the example programs, e.g. messages like<pre>         can't load library 'libqt.so.2'</pre>    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.</p><li> 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/</p></ul><p>You're done.
