It may needto be modified for other platforms.<p> <ol type=1><li> Unpack the archive if you have not done so already<p> <pre> cd <anywhere>; gunzip qt-embedded-VERSION-commercial.tar.gz # uncompress the archive tar xf qt-embedded-VERSION-commercial.tar # unpack it</pre> Replace VERSION with the Qt/Embedded version number throughout.<p> This document assumes that the archive is installed as <tt>~/qt-VERSION</tt>. <li> Compile the Qt/Embedded library and examples.<p> <pre> cd ~/qt-VERSION export QTDIR=~/qt-VERSION ./configure make</pre> <p> The configuration system is designed to allow platform-specific optionsto be added, but in general all Linux system which have framebuffersupport can use the "linux-generic-g++" platform.The configuration system also supports cross-compilers:to build <em>on</em> Linux/x86 <em>for</em> the Linux/MIPSEL target, you would use:<pre> ./configure -platform linux-x86-g++ -xplatform linux-mips-g++</pre> <p> Only a small number of configurations are predefined, all much the same.Configurations files are found in <tt>configs/</tt>.<p> <li> Enable framebuffer support.<p> You may need to recompile your kernel to enable the framebuffer.This document does not describe how to do this; the<a href="emb-framebuffer-howto.html">HOWTO-Framebuffer page</a>contains a short description. (You should seea penguin logo at boot time when the frame buffer is enabled.)<p> For Matrox G100/G200/G400 use the matrox frame buffer driver.<p> For NVidia TNT cards use the nvidia frame buffer driver.<p> For Mach64 and most other cards, use the vesafb driver.<p> Note that some cards are only supported in VGA16 mode, this willnot work with the current version of Qt/Embedded, since VGA/16 isnot yet supported. You may need to upgrade your kernel, or evenswitch to an experimental kernel.<p> The frame buffer must also be enabled with a boot parameter. See<tt>/usr/src/linux/Documentation/fb</tt> for details.<p> The <tt>fbset</tt> program, which should be included in Linux distributions,may be used to switch video modes without rebooting the system. Thevideo mode active when the server is started will be used. (8-bitmodes are still experimental.) <b>Note</b>: <tt>fbset</tt> does not workwith the vesafb driver.<p> <li> Change permissions.<p> To run Qt/Embedded, you need write access to the framebuffer device<tt>/dev/fb0</tt>. <p> You also need read access to the mouse device. (Note that<tt>/dev/mouse</tt> is normally a symbolic link; the actual mouse devicemust be readable.)<p> <li> How to run the demonstration program.<p> Log into a virtual console and do:<p> <pre> cd ~/qt-VERSION/ ./start-demo</pre> <p> <li> Miscellaneous troubleshooting and known bugs.<p> To kill gpm, run the following command as root:<p> <pre> gpm -k</pre> <p> In some cases, if the server does not work, it will work when run as root.<p> Some example programs may not compile with GCC 2.95.<p> Show processes using the framebuffer:<p> <pre> fuser -v /dev/fb0</pre> <p> Kill such processes:<pre> fuser -vk /dev/fb0</pre> or harsher:<pre> fuser -k -KILL /dev/fb0</pre> <p> Show existing semaphores:<pre> ipcs </pre> <p> Remove semaphores:<pre> ipcrm</pre> <p> The communication between client and server is done through thenamed pipe <tt>/tmp/.QtEmbedded</tt>; sometimes it may need to be deleted(eg. if you run Qt/Embedded as root then later as an unprivileged user).<p> <li> Customization.<p> The Qt/Embedded library can be reduced in size by<a href="emb-features.html">removing unnecessary features</a>.<p> </ol><p> <!-- eof --><p><address><hr><div align=center><table width=100% cellspacing=0 border=0><tr><td>Copyright © 2002 <a href="http://www.trolltech.com">Trolltech</a><td><a href="http://www.trolltech.com/trademarks.html">Trademarks</a><td align=right><div align=right>Qt version 3.0.5</div></table></div></address></body></html>⌨️ 快捷键说明
