I tried using the supplied SGE library here for PSP and ran into many issues when compiling against my own applications (missing support for some libraries I needed, plus there were truncating issues).

Therefore, I downloaded the source from the official site: http://www.etek.chalmers.se/~e8cal1/sge/ and ported over the source myself.


One thing I noticed as well was that the version checked in SVN was a little outdated and was missing SDL_image, Freetype, and C++ Class support. Its all included in this lib.


Details are covered in the README.PSP file. but here are the instructions and requirements anyway.

sound very interesting, thanks for porting this. Also i have my project at half so i'll won't use it i have read the specs and are very good.

Im sorry if this is too noob.
In the examples inside the SGE, why do these examples run on the psp without the PSP_MODULE_INFO, exit callbacks, etc all the things I thought was necessary for a psp program?

[Smong]

SGE is ontop of SDL and I think SDL does all that for you, it tells the compiler to use SDL_main instead of main as the entry point so it can secretly set stuff up (SDL_main calls main when it's done).

ok thank you.

So wouldn't that mean I can't easily change it to kernel mode?
Or if theres a different way of setting module info up, enlighten me please?

[Smong]

Why do you need kernel mode? If you really need it then I think the preferred method is to put your kernel mode things into a separate prx and load that from your main program. There are some threads that explain it using sample code from HEN http://forums.ps2dev.org/viewtopic.php?p=58259#58259

There is a way to remove SDL's secret main, use this line in CFLAGS instead of sdl-config (I took out -Dmain=SDL_main):
-I/usr/local/pspdev/psp/include/SDL
You'd have to setup your own exit callback and whatever else SDL did in it's SDL_main (could just check the source code).

[fatdev]

I need it to set up wlan. I will probably do it the first way you mentioned(seperate prx).

But just in case I find out I need to do it the other way for whatever reason, I briefly looked through SDL_main.h in usr/local/pspdev/psp/include SDL but it seems to have words like W32 and MacOS....is this the one I should be looking at? plus there isnt exit callback etc in this, or other header files in the same folder...

[Smong]

I actually meant the .c file not the .h file. Since I used the psplibraries script I have it here: X:\psplibraries\build\SDL\src\main\psp\SDL_psp_main.c
There's a copy on google code too: http://www.google.com/codesearch?hl=en&lr=&q=file%3ASDL_psp_main%5C.c&btnG=Search

Interestingly it seems SDL programs start in kernel mode anyway, so you may not have to do anything special.

[fatdev]

ooo~ right-o it is. Oh well then I have nothing to worry about. Thanks for the tip Smong.
