OpenHandhelds gp2x File Archive - File Info - Home:gp2x

Updated: 22nd October 2006.

This is a program that I originally wrote to test out some of the SDL functions and extra Libraries such as SDL_TTF, SDL_Image, SDL_Mixer to see if they are working correctly with my dev setup.

No idea if it will be of any use to people but it makes a nice first program to compile and test your dev setup and also to maybe learn how to setup a program to run on the GP2X and PC. It is also used a s an example in the GP2X User Guide for the introduction to developing on the GP2X.

So far it does a test for the usual libs such as the below and more:

SDL_TTF - True Type Font text
SDL_Mixer - WAV, MOD, MP3 and OGG playback. OGG playback has volume and pause controls. MOD Playback seems to be slow at the moment, possible bug when compiling for GP2X?
SDL_Image - PNG, BMP and JPEG display with and without transparency
Input - GP2X and PC simulated buttons, useful when testing on PC
SDL Timer - Small example to make a timer

NOTE: To save download time I have not included example MP3 or OGG files. To do the test you must have a music.mp3 and music.ogg in the /sdltest/ folder.

If you do want to test a certain function just comment out the functions code and it should run fine. Dont forget to copy the /sdltest/ folder to your SD Card otherwise it wont run correctly, I also added a GPE if you just want to check it out without compiling.

This is an awesome test program... Thank you!!! I had to add in the line to allow the GP2X to choose the MOD Test, but it crashed the unit after a few seconds of playing. Also, the standard 'accept' button is B, not X.

Guyfawkes:

mod playback seems to be dodgy in sdl at the moment, its why i originally disabled the option in the first release of this test code. the problem may be part due to the mod i used but i tried a few and all had problems.

SOLInvictus:

When i try to compile (crosscompile under windows) i get the following error: > "make" C:/devkitGP2X/bin/arm-linux-g++ -static -o sdltest.gpe sdltest.o `C:/devkitGP2X/bin/arm-linux-sdl-config --libs` sdltest.o: In function `Shutdown()': sdltest.cpp:(.text+0x24): undefined reference to `Mix_FreeChunk' sdltest.cpp:(.text+0x30): undefined reference to `Mix_FreeMusic' sdltest.cpp:(.text+0x34): undefined reference to `Mix_CloseAudio' sdltest.cpp:(.text+0x40): undefined reference to `TTF_CloseFont' sdltest.cpp:(.text+0x44): undefined reference to `TTF_Quit' sdltest.o: In function `LoadFont(unsigned char)': sdltest.cpp:(.text+0x8c): undefined reference to `TTF_OpenFont' sdltest.o: In function `drawText(SDL_Surface*, char*, int, int, int, int, int)': sdltest.cpp:(.text+0xe8): undefined reference to `TTF_RenderText_Blended' sdltest.o: In function `drawTextInt(SDL_Surface*, int, int, int, int, int, int)': sdltest.cpp:(.text+0x190): undefined reference to `TTF_RenderText_Blended' sdltest.o: In function `TestSDLImage()': sdltest.cpp:(.text+0x3e0): undefined reference to `IMG_Load' sdltest.cpp:(.text+0x494): undefined reference to `IMG_Load' sdltest.cpp:(.text+0x534): undefined reference to `IMG_Load' sdltest.o: In function `TestSDLMixerWAV()': sdltest.cpp:(.text+0xae8): undefined reference to `Mix_LoadWAV_RW' sdltest.cpp:(.text+0xb08): undefined reference to `Mix_PlayChannelTimed' sdltest.cpp:(.text+0xb14): undefined reference to `Mix_Playing' sdltest.o: In function `TestSDLMixerOGG()': sdltest.cpp:(.text+0xbc4): undefined reference to `Mix_LoadMUS' sdltest.cpp:(.text+0xbd4): undefined reference to `Mix_PlayMusic' sdltest.cpp:(.text+0xdb8): undefined reference to `Mix_ResumeMusic' sdltest.cpp:(.text+0xe04): undefined reference to `Mix_HaltMusic' sdltest.cpp:(.text+0xe28): undefined reference to `Mix_RewindMusic' sdltest.cpp:(.text+0xe30): undefined reference to `Mix_RewindMusic' sdltest.cpp:(.text+0xe44): undefined reference to `Mix_VolumeMusic' sdltest.cpp:(.text+0xe78): undefined reference to `Mix_ResumeMusic' sdltest.cpp:(.text+0xe90): undefined reference to `Mix_VolumeMusic' sdltest.cpp:(.text+0xea4): undefined reference to `Mix_PauseMusic' sdltest.cpp:(.text+0xeb0): undefined reference to `Mix_PauseMusic' sdltest.o: In function `TestSDLMixerMOD()': sdltest.cpp:(.text+0xf68): undefined reference to `Mix_LoadMUS' sdltest.cpp:(.text+0xf78): undefined reference to `Mix_PlayMusic' sdltest.cpp:(.text+0xf88): undefined reference to `Mix_HaltMusic' sdltest.o: In function `main': sdltest.cpp:(.text+0x10ec): undefined reference to `TTF_Init' sdltest.cpp:(.text+0x1100): undefined reference to `Mix_OpenAudio' "make": *** [sdltest.gpe] Error 1

Guyfawkes:

SOLInvictus - make sure that the arm-linux-sdl-config.rar is downloaded and extracted to the correct place as shown in the guide.

SOLInvictus:

Hi Guyfawkes! I tried to find a arm-linux-sdl-config.rar but the only link i got is not working anymore - get a 404 ( https://www.emuholic.com/arm-linux-sdl-config.rar ). So where to download that?

Guyfawkes:

sorry SOLInvictus, i had changed the DNS on monday for emuholic.com as the domain is changing server. download the new v1.2.1 user guide which should be online shortly for a new dev setup section or download theoodbots libs in the Development -> Libraries section as this now contains the needed arm-linux-sdl-config files. sorry for the trouble its caused, had to change the DNS though.

SOLInvictus:

Thx Guyfawkes!! It worked for me! I only get one warning: > "make" C:/devkitGP2X/bin/arm-linux-g++ -static -o sdltest.gpe sdltest.o `C:/devkitGP2X/bin/arm-linux-sdl-config --libs` C:/devkitGP2X/lib\libmikmod.a(mdriver.o): In function `MD_DropPrivileges': mdriver.c:(.text+0x2cf4): warning: Using 'getpwnam' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking C:/devkitGP2X/bin/arm-linux-strip sdltest.gpe > Process Exit Code: 0

Guyfawkes:

you can ignore the Using 'getpwnam'... error

Dingo_aus:

This is such a great demonstration! Thank you so much, it is exactly what I was looking for. If you download it and want a good guide on how to compile it on your Windows box for yourself, see here: https://wiki.gp2x.org/wiki/Using_CodeBlocks

Noldor:

Seems sdltest.h file is missing in 1.5 version!

Guyfawkes:

sorry, somehow I forgot to add the file to the zip. I have just submitted an update and when its accepted you can download v1.51

Guyfawkes:

you can also download the latest version from my software homepage at https://www.emuboards.com/guyfawkes/

Noldor:

thanks ;)

james90100:

will someone pleas make a wifi suport so we can use all thes web browsers?!?!?!?!?!?!?!?!

heavensdoor:

Useful ! Tnx. Just a note... it would be better to change the Makefile, adding a var: DEVKIT_GP2X = $(DEVKITARM) and changing every "C:/devkitGP2X" string with "$(DEVKIT_GP2X)"

Hangman:

Great piece of code, thank you!

KermEd:

KermEd:

Something to do with this maybe: cannot find -lsmpeg
