==============================================================================
Using the Simple DirectMedia Layer with EPOC/SymbianOS 6.0
==============================================================================
==============================================================================
I. Building the Simple DirectMedia Layer libraries:
You can get Symbian SDK from:
http://www.symbian.com.
First create "Epoc" directory under SDL main directory and unpack
EpocBuildFiles.zip in it.
To build the librarys goto "epoc" directory and type:
bldmake bldfiles
abld makefile vc6 (for creating Microsoft Visual C++ makefiles)
abld build wins udeb (building for wins emulator)
abld build armi urel (building for real device)
==============================================================================
II. Building the Simple DirectMedia Layer programs:
Building SDL test programs is easy once you have built the libraries:
abld test build wins udeb
abld test build armi urel
Supported real screen resolutions
320 x 200 x 8 bit
320 x 200 x 12 bit
640 x 200 x 8 bit
640 x 200 x 12 bit
Supported "emulated" screen resolutions
640 x 400 x 8 bit
640 x 400 x 12 bit
640 x 480 x 8 bit
640 x 480 x 12 bit
"Emulated" resolutions are implemented by by shrinking the screen vertically
i.e. only every second scanline is drawn. This is mainly ment to be used for
testing quick ports of programs. Using faked resolutions is a waste of memory
and cpu power!
==============================================================================
III. Running test programs
Copy executable to the device and run it from the File manager. The Esc
key quits demo programs. In Crystal, Exe programs do not appear in task list
nor in Extras :-(. Test programs are tested in Nokia 9210 Communicator.
Special keys used in SDL:
The Caps lock key enables or disables the virtual cursor.
Function keys are mapped as follows:
F1=chr+q, F2=chr+w,..., F8=chr+i,
F9=chr+a,..., F12=chr+d.
==============================================================================
IV. 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
You can find more info about Epoc version of SDL from Hannu Viitala's
homepage
http://www.mbnet.fi/~haviital
