Well, I searched and read everything about this on forums, but I'm still getting problem to build my SDL application (that runs fine on 1.50) to run on 3.52.

My Makefile has:

Your heap size is probably too big. Try PSP_HEAP_SIZE_MAX() instead. That sets it to the biggest value without going over the limit. Using PSP_HEAP_SIZE_KB() means you have to guess how much you can get away with before it fails.

Just tried that, still not working. I got the same error. :(

Hmm... sounds like you still have a kernel level call in your code somewhere. Any kernel calls at all will make your program error out with that code. All kernel calls need to be moved into an external prx for 3.xx homebrew.

The SDL library has a call to a kernel function, the one that sets the exception handler.

You have to change the SDL source and recompile/reinstall it. Of course it would be better if someone commited the changes to the svn using preprocessor conditional code based on the PSP_FW_VERSION.

Tbh is it probably simpler to just not use SDL_main :P

Other option is to make the libraries that have the calls to the kernel only functions with the bind flag, it may work.

Well tbh SDL doesn't need kernel libraries at all, it is a relic of a bygone era, but I am loath to do much about it when using SDL_main is not really needed in the first place (and not using it removed any kernel dependencies) and the hassle of maybe having two different SDL_mains and the associated defaults.

Anyway, the use of SDL_main is just for easy portability (in other words, just recompilation), its no problem to implement SDL_main in my code, but I think its better to fix SDL on svn and no need to maintain two SDL_main versions. Why we need keep 1.50 compatibility?

I will test changing my SDL_main to see if it works.

EDIT:
No, I can't get it to work.
Where is defined PSP_HEAP_SIZE_MAX() ? I just can't find it here... There is a way to check which sdk version I'm using? :)

It's in libpspkernel and psplibc and libc (newlib). There was a problem with MAX on older versions of psplibc, but not many people use both psplibc and MAX, so it wasn't discovered for a while. PSP_HEAP_SIZE_MAX just sets a var that libc looks for when making the heap on startup. It's just like PSP_HEAP_SIZE_KB in that respect. They both set the same variable that's used by libc to make the heap. You should really be using the very latest SDK for the latest changes in Slim support.

Ok. Just updated to svn pspsdk. This is the sample I'm trying to run:

Works just fine for me on a 3.6 slim

Is it a runtime problem or a compilation problem the last one you are having?

J.F. · Joined: 22 Feb 2004 Posts: 2906

You need to make this change in the makefile:

fungos · Joined: 31 Oct 2007 Posts: 41 Location: cwb br

J.F.: I tried you suggestion, still not working.

I'm trying to run with 3.52 M33-4 CFW.
I have some runtime problem, looks like its crashing my psp. First, its run but nothing is shown, then If I try to quit it by home button, it reboots or freeze in that message "Please wait...".

Anyone with this same firmware can reproduce or with any fat psp?
Good that works on slim 3.6 and 3.71. I'm just afraid to upgrade my fat to 3.6x/3.7x for now... :S

Just tried it on my old Phat with 3.52 M33-4. It works fine. So now you have two things to consider: 1 - The problem is with your toolchain/sdk. Solution - reinstall completely. 2 - The problem is with your PSP. Solution - reinstall cfw... maybe. It could also be a problem with a plugin. If you use plugins, disable them. If you have custom fonts and rcos installed, uninstall them.

EDIT: Try this EBOOT. It works on both my PSPs. If this works for you, the problem is your toolchain. If it fails, the problem is your PSP.

I'm really surprised that that would work at all for several reasons.
Let's take a look at SDL_psp_main.c:

J.F.: Thanks man, that worked here. So, I will try to reinstall my toolchain and try again tomorrow night.

Archaemic: This sample doesn't use SDLmain.a, look again at my Makefile. But thanks for your SDL patch (I saw the other post), I will test it here tomorrow too. Would be nice have that in svn.

I will test with a new toolchain and then I will post the result here.
Thank you everybody, you all are very helpful!! :D

Ahhh, I completely forgot that SDLmain was a separate library. My mistake.

The weird thing is, I just reinstalled psptoolchain and It still not working. But I noticed that my eboot.pbp has different size from yours, look:

mine:

Well, if you're trying to build the toolchain in Windows with CygWin, I know people have all kinds of trouble. I'm using Ubuntu, like most of the folks who don't have trouble. It's just easier to do it in linux.

So, I don't have windows anywhere near me :)
I use kubuntu and my notebook is a AMD64x2.
And, I just reinstalled all libraries (psplibraries script).
Anyway, this problem is very exoteric. I think I should let it alone and still developing for 1.50 :(

Hi,

I had this problem until a day ago :-)

I fixed it by changing the sdl-config file so that it when i call -nosdlmain it removes any instances of SDL main so that it will work on the 3.71 kernel.

You have to remove it from the Cflags and the libraries then do something with the program itself so it includes the module info etc. (compiler will ask for them)

Give that a shot and let us know how it went. If you need my sdl-config file, PM me.

Wally4000: Thanks for your help, but I'm trying exaclty that (I'm not using sdl_config neither SDLmain.a) :)

J.F.:
I have done that change to env to setup pkgconfig path, DELETED all my libraries and installed again using psplibraries. Then I tried to compile it again, and it still crashing my psp (and the output eboot still with that size)

Then I commented out all SDL code and fixed Makefile to not use -lSDL (and -lGL as consequence). And the new eboot (with about ~90kb) worked. Then again, I enabled ONLY SDL_InitSubSystem and nothing more and it crashed again.

The problem IS WITH SDL. I dont know what is causing this problem (something with video initialization). So I whant to compare my libraries size with yours if possible.

Yes, I was using this Makefile ;)
But to be sure, I copied it and tried again. Still the same problem :(

I noticed that your libraries has different sizes from mine, maybe it's really some problem with my SDL building.

This is the output of building my eboot:

Here's my libGL.a and libSDL.a.

Thanks J.F., it doesn't worked too. :S
But its ok, now I know how to make 3.xx applications. :)
I think I can't find what is happening, but I hope it will eventually start working.... lol

Bye
