You can list all of the configuration system's + options by typing \c {./configure -help}. + + Note that by default, \l{Qt for Embedded Linux} is configured for + installation in the \c{/usr/local/Trolltech/QtEmbedded-%VERSION%} + directory, but this can be changed by using the \c{-prefix} + option. Alternatively, the \c{-prefix-install} option can be used + to specify a "local" installation within the source directory. + + The configuration system is also designed to allow you to specify + your platform architecture: + + \snippet doc/src/snippets/code/doc_src_emb-install.qdoc 2 + + In general, all Linux systems which have framebuffer support can + use the \c generic architecture. Other typical architectures are + \c x86, \c arm and \c mips. + + \note If you want to build Qt for Embedded Linux for use with a virtual + framebuffer, pass the \c{-qvfb} option to the \c configure + script. + + To create the library and compile all the demos, examples, tools, + and tutorials, type: + + \snippet doc/src/snippets/code/doc_src_emb-install.qdoc 3 + + On some systems the \c make utility is named differently, e.g. \c + gmake. The \c configure script tells you which \c make utility to + use. + + If you did not configure \l{Qt for Embedded Linux} using the \c{-prefix-install} + option, you need to install the library, demos, examples, tools, + and tutorials in the appropriate place. To do this, type: + + \snippet doc/src/snippets/code/doc_src_emb-install.qdoc 4 + + and enter the root password. + + \note You can use the \c INSTALL_ROOT environment variable to specify + the location of the installed files when invoking \c{make install}. + + \section1 Step 4: Adjusting the Environment Variables + + In order to use \l{Qt for Embedded Linux}, the \c PATH variable must be extended + to locate \c qmake, \c moc and other \l{Qt for Embedded Linux} tools, and the \c + LD_LIBRARY_PATH must be extended for compilers that do not support + \c rpath. + + To set the \c PATH variable, add the following lines to your \c + .profile file if your shell is bash, ksh, zsh or sh: + + \snippet doc/src/snippets/code/doc_src_emb-install.qdoc 5 + + In case your shell is csh or tcsh, add the following line to the + \c .login file instead: + + \snippet doc/src/snippets/code/doc_src_emb-install.qdoc 6 + + If you use a different shell, please modify your environment + variables accordingly. + + For compilers that do not support \c rpath you must also extend + the \c LD_LIBRARY_PATH environment variable to include + \c /usr/local/Trolltech/QtEmbedded-%VERSION%/lib. Note that on Linux + with GCC, this step is not needed. + + \section1 Step 5: Building the Virtual Framebuffer + + For development and debugging, \l{Qt for Embedded Linux} provides a virtual + framebuffer as well as the option of running \l{Qt for Embedded Linux} 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: + + \list + \o \l {The Virtual Framebuffer} + \o \l {The VNC Protocol and Qt for Embedded Linux} + \endlist + + Note that the virtual framebuffer requires a Qt for X11 + installation. See \l {Installing Qt on X11 Platforms} for details. + + The Linux framebuffer, on the other hand, is enabled by default on + all modern Linux distributions. For information on older versions, + see \l http://en.tldp.org/HOWTO/Framebuffer-HOWTO.html. To test + that the Linux framebuffer is set up correctly, use the program + provided by the \l {Testing the Linux Framebuffer} document. + + That's all. \l{Qt for Embedded Linux} is now installed. + + \table 100% + \row + \o + \bold {Customizing the Qt for Embedded Linux Library} + + When building embedded applications on low-powered devices, + reducing the memory and CPU requirements is important. + + A number of options tuning the library's performance are + available. But the most direct way of saving resources is to + fine-tune the set of Qt features that is compiled. It is also + possible to make use of accelerated graphics hardware. + + \list + \o \l {Fine-Tuning Features in Qt} + \o \l {Qt Performance Tuning} + \o \l {Adding an Accelerated Graphics Driver to Qt for Embedded Linux} + \endlist + + \endtable +*/ |
