Setting up the Qtopia development environment. + + This document will not explain how to setup the Qtopia development + environment. That is outside the scope of the document. You can read + more on this subject in this excellent howto: + + http://www.zauruszone.com/howtos/linux_compiler_setup_howto.html + +============================================================================== +II. Building the Simple DirectMedia Layer libraries using the arm + cross-compiler + + This is somewhat tricky since the name of the compiler binaries + differ from the standard. Also you should disable features not + needed. The command below works for me. Note that it's all one + line. You can also set the NM, LD etc environment variables + separately. + + NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ RANLIB=arm-linux-ranlib AR=arm-linux-ar ./configure --enable-video-qtopia --disable-video-dummy --disable-video-fbcon --disable-video-dga --disable-arts --disable-esd --disable-alsa --disable-cdrom --disable-video-x11 --disable-nasm --prefix=/opt/Qtopia/sharp/ arm-unknown-linux-gnu + + One thing to note is that the above configure will include joystick + support, even though you can't have joysticks on the Zaurus. The + reason for this is to avoid link / compile / runtime errors with + applications that have joystick support. + +============================================================================== +III. Building the Simple DirectMedia Layer test programs: + + After installing, making sure the correct sdl-config is in your + path, run configure like this: + + NM=arm-linux-nm LD=arm-linux-ld CC=arm-linux-gcc CXX=arm-linux-g++ AR=arm-linux-ar ./configure arm-unknown-linux-gnu + +============================================================================== +IV. Application porting notes + + One thing I have noticed is that applications sometimes don't exit + correctly. Their icon remains in the taskbar and they tend to + relaunch themselves automatically. I believe this problem doesn't + occur if you exit your application using the exit() method. However, + if you end main() with 'return 0;' or so, this seems to happen. + + Also note that when running in landscape mode - i.e requesting a + window that is HEIGHT pixels wide and WIDTH pixels high, where WIDTH + and HEIGHT normally is 240 and 320 - the image is blitted so that + the hardware buttons are on the left side of the display. This might + not always be desirable but such is the code today. + + +============================================================================== +V. Enjoy! :) + + If you have a project you'd like me to know about, or want to ask questions, + go ahead and join the SDL developer's mailing list by sending e-mail to: + + sdl-request@libsdl.org + + and put "subscribe" into the subject of the message. Or alternatively you + can use the web interface: + + http://www.libsdl.org/mailman/listinfo/sdl + +============================================================================== +VI. What is supported: + +Keyboard (Sharp Zaurus) +Hardware buttons +Stylus input (mouse) +Video. Allows fullscreen both in portrait mode (up to WIDTHxHEIGHT +size window) and in landscape mode (up to HEIGHTxWIDTH). + +All other SDL functionality works like a normal Linux system (threads, +audio etc). + +-- +David Hedbor <david@hedbor.org> +http://david.hedbor.org/ http://eongames.com/ + |
