I've been hearing alot about SDL. What is it?

**foXtrot** · 05-24-2006, 06:05 PM

Wikipedia explains it pretty well http://en.wikipedia.org/wiki/Simple_DirectMedia_Layer

**Zettablade** · 05-24-2006, 06:16 PM

How does it compare speed wise to the psp sdk?

**danzel** · 05-24-2006, 06:31 PM

SDL is all rendered in software, so its not too fast.
But It is fairly fast (fast enough) in 16bit color (see commander keen for a good example).
Check out OSLib if you want something fast and easy for psp.
SDL does have the advantage of being crossplatform however, which is why I use it.

Search on Google

**Zettablade** · 05-24-2006, 06:47 PM

I all ready know about google, but google isn't the most precise, so I'de rather ask a person.

Well, not to be rude, but the first result on google is the sdl website.

SDL is a pain in the arse to install, setup, and use effieciently... I wish you luck... If you have some libs already installed before SDL, you will not be able to install SDl... (libogg and libvorbis are exampels...)

HA pain in the ass? I downloaded the SDL run time package, installed it with a simple drag and drop. Then I did the same for SDL_image and SDL_ttf and BAM

My laptop compiled my program. It's quite possibly the easiest setup I've ever done.

**Zettablade** · 05-24-2006, 09:23 PM

meh, cygwin is easy to use, so I'm gonna stick with the sdk. SDL doesn't sound too good anyways.

Ha, that is until you start using it and then it's the BEST THING EVER!

**Zettablade** · 05-25-2006, 10:03 AM

but using cygwin is so simple. I can download any library and install it with just a few keystrokes. all i have to do to compile my programs is type make.
honestly, you say it's good, but i'm not looking for some easy wya out of coding. anyways, sdl is executes slow, and i need to execute pretty fast for the type of game I'm working on.

SDL is a library for Cygwin, so I don't know how can you use SDL or Cygwin.

SDL should be considered God's Gift To PSPs,

And yes, it can be used on just about any platform. Insatlling it can be tricky, but I assure you installing it is only half as complicated as using the native PSP GU functions. And, once you start using SDL you will gain enough knowledge about the GU functions that you can slowly start using them (should you choose too).

As for speed, I suspect it is faster than LUA if somone was to do a benchmark. And it will definatly be faster if you work in some native GU functions here and there. And baby oh baby, the SDL online documention is a treat to anyomne who has tried to learn graphics programming on their PSP. Using SDL you get acces to libraries that can do just about anything you want, and again, should you chose to you can ignore those libraries and easily write your own. I couldn't possibly sing enough priase, so I will be on my mery way.

lol
I know lua, but I don't like it. It just feels TOO easy. But I wanna know how the homebrew sdk goes up against osl and the sdl in a benchmark. If any one could post some results, that would be just awsome.

**danzel** · 05-25-2006, 04:57 PM

OSLib uses the Gu to do its rendering, so it will be fast.
SDL does have awesome documentation, I forgot about that one! (I'm just so used to it, lmao)
You will most likely find SDL is fast enough for you, but try what you want and report back

I haven't seen a benchmark around.

Yeah, Danzel said it was "slower" earlier... But I really dont' think you'll ever notice the speed in anything you could be running on the PSP. My program compiles/loads/runs ULTRA fast...

Coding on a Macbook Pro I see...how's that working out for you?
Installing and compiling the PSPSDK on my mini was a snap, even if it took almost forever (stupid T-DSL!).

Well I gave up on the SDK when fink wasn't universal yet... just coding natively using SDL then gonna port it back over (the G5 has the pspsdk running fine).

But overall I love it =) One of these days I'll take the time to manually install the tools I need for PSPSDK on macbook pro
