chrisp....i'm fairly certain the following line should be placed underneath psp_module_info:

PSP_MAIN_THREAD_ATTR(THRE AD_ATTR_USER) <--i think you should only need THREAD_ATTR_USER for this app only but someone correct me if wrong

Hmm... weird, I read somewhere today to put :
PSP_MAIN_THREAD_ATTR(PSP_ THREAD_ATTR_USER);
under it, but it didn't work either. I tried the one you suggested also, but still no go.


Do you think it could be something with my sdk or something like that?

[bnc9]

Instead of pspdebug.h use stdio.h(for the proper printf) as far as I know pspdebug.h doesn't work well in user mode (but I could be wrong).

[Archaemic]

You are wrong. The proper printf won't do anything, especially because the defines will make you unable to access it.

[bnc9]

chrisp-- well there's nothing wrong with your code it compiled and ran fine try putting it in the GAME371 folder maybe thats your problem(again I might be wrong I ran it on psplink).

[THExGOLDxAVENGR]

Im new at programming for the psp and i want to make my own app/game (not sure yet) and i was looking at some of the Libraries out on dl.qj and i saw the psp dialog box library. i thought i might look at that and see what it could do. so i downloaded it and i unzipped and was lost. i realized i had no idea where i was supposed to put the .h and .c files. i have made the simple programs like diplaying text graphics and mp3 playing but havent gone any farther.

i just wanted to know how im supposed to install custom libraries.

i found the dialog library here:

thanks for the help

3.xx homebrew you must run the prx in psplink... (sorry if that's irrelevant, i dont want to read the entire situation :P)

i was wondering does CSP development studio has an png librarie?

[bnc9]

CSP should have it but you're better off not using it and installing the toolchain with cygwin(it takes a few trys but I got it on my first) because CSP contains an old version of the SDK and it's difficult to use (no offense ManiacX :) .

[dan369]

How do you install the Toolchain with cygwin?

What's the difference between

sceDisplayWaitVblank

and

sceDisplayWaitVblankStart

Which one is for what?

PS: I read Header definition.

[Archaemic]

Just a guess, but one probably waits for a vblank to finish, and the other waits for a vblank to start.

[dan369]

Can you Change

SceCtrlData pad;

So u could instead have

 
SceCtrlData menupad

Then you'd would put

 
if (padmenu.Buttons & PSP_CTRL_DOWN) {
printf("Your Pressing Down\n");
}

I think that would be right :? im still learning C.

[Archaemic]

Well, if you keep your variable names straight :P

I am having a problem getting lightmp3 libraries to compile. I have libogg installed but I still get

But that doesn't make any sense...
:Argh:

[yaustar]

But that doesn't make any sense...
:Argh:

Actually it does, one waits until the rendering starts (i.e when VBlank finishes), the other waits until the the rendering finishes (i.e. when VBlank starts).

Read: http://en.wikipedia.org/wiki/Vertical_blanking_interval

[Art]

I think he means because the start and finish is the same time,
ie, start of the next one is the finish of the last one.
I guess this isn't the case because a frame has to sit on the screen for some time so you see it.

[yaustar]

I think he means because the start and finish is the same time,

It isn't. Here is some further reading material:

I need some help implementing sound in PSP pileup, ive tried using libmad but my compiler seems to not like it, it comes up with tonnes of errors e.g MAD_BUFFER_GUARD undeclared etc etc, it keeps on going on saying that everything is undeclared. if it helps i'm using cygwin from CSP and am using a slightly out of date libmad. i cant update because cygwin doesnt like this either.... help?

[Archaemic]

Did you include the proper headers...?

[Llanowyn]

If anyone here has the patience to tutor(read: answer some questions and point me in the right direction) a new coder in the ways of C and using OSLib, I would graciously appreciate the help. I'm afraid that with 855 pages in this thread, there's just too much here for me to wade through.

You can contact me by:

Thank you for your help!

Edit: Firefox double posted for me V_V.

[SuperBatXS]

Hey,
I tried to update my SDK, but i get an error that i don't have PSPDEV installed...what should i do?

[Moose]

Do you even have the PSP toolchain installed?

[SuperBatXS]

I "svn"ed it; i have it downloaded; i can cd into it. Obviously, my cygwin is working because i can compile.
