You can list all of the configuration system's options by typing <tt>./configure -help</tt>.</p> <p>Note that by default, Qtopia Core</tt> is configured for installation in the <tt>/usr/local/Trolltech/QtopiaCore-%VERSION%</tt> directory, but this can be changed by using the <tt>-prefix</tt> option. Alternatively, the <tt>-prefix-install</tt> option can be used to specify a "local" installation within the source directory.</p> <p>The configuration system is also designed to allow you to specify your platform architecture:</p> <pre> cd ~/qtopia-core-commercial-src-%VERSION% ./configure -embedded [architecture]</pre> <p>In general, all Linux systems which have framebuffer support can use the <tt>generic</tt> architecture. Other typical architectures are <tt>x86</tt>, <tt>arm</tt> and <tt>mips</tt>.</p> <p>To create the library and compile all the demos, examples, tools, and tutorials, type:</p> <pre> make</pre> <p>On some systems the <tt>make</tt> utility is called differently, e.g. <tt>gmake</tt>. The <tt>configure</tt> script tells you which <tt>make</tt> utility to use.</p> <p>If you did not configure Qtopia Core</tt> using the <tt>-prefix-install</tt> option, you need to install the library, demos, examples, tools, and tutorials in the appropriate place. To do this, type:</p> <pre> su -c "make install"</pre> <p>and enter the root password.</p> <p><b>Note:</b> You can use the <tt>INSTALL_ROOT</tt> environment variable to specify the location of the installed files when invoking <tt>make install</tt>.</p> <a name="step-4-adjusting-the-environment-variables"></a> <h3>Step 4: Adjusting the Environment Variables</h3> <p>In order to use Qtopia Core</tt>, the <tt>PATH</tt> variable must be extended to locate <tt>qmake</tt>, <tt>moc</tt> and other Qtopia Core</tt> tools, and the <tt>LD_LIBRARY_PATH</tt> must be extended for compilers that do not support <tt>rpath</tt>.</p> <p>To set the <tt>PATH</tt> variable, add the following lines to your <tt>.profile</tt> file if your shell is bash, ksh, zsh or sh:</p> <pre> PATH=/usr/local/Trolltech/QtopiaCore-%VERSION%/bin:$PATH export PATH</pre> <p>In case your shell is csh or tcsh, add the following line to the <tt>.login</tt> file instead:</p> <pre> setenv PATH /usr/local/Trolltech/QtopiaCore-%VERSION%/bin:$PATH</pre> <p>If you use a different shell, please modify your environment variables accordingly.</p> <p>For compilers that do not support <tt>rpath</tt> you must also extend the <tt>LD_LIBRARY_PATH</tt> environment variable to include <tt>/usr/local/Trolltech/QtopiaCore-%VERSION%/lib</tt>. Note that on Linux with GCC, this step is not needed.</p> <a name="step-5-enabling-framebuffer-support"></a> <h3>Step 5: Enabling Framebuffer Support</h3> <p>For development and debugging, Qtopia Core</tt> provides a virtual framebuffer as well as the option of running Qtopia Core</tt> as a VNC server. For a description of how to install the virtual framebuffer and how to use the VNC protocol, please consult the documentation at:</p> <ul> <li><a href="qtopiacore-qvfb.html">Qtopia Core's Virtual Framebuffer</tt></a></li> <li><a href="qtopiacore-vnc.html">The VNC Protocol and Qtopia Core</tt></a></li> </ul> <p>Note that the virtual framebuffer requires a Qt/X11 installation. See <a href="install-x11.html">Installing Qt/X11</tt></a> for details.</p> <p>The Linux framebuffer, on the other hand, is enabled by default on all modern Linux distributions. For information on older versions, see <a href="http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html">http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html</tt></a>. To test that the Linux framebuffer is set up correctly, use the program provided by the <a href="qtopiacore-testingframebuffer.html">Testing the Linux Framebuffer</tt></a> document.</p> <p>That's all.
