GP2X Math Libs?

[nickspoon]

Currently trying to port flirt (a Flash runtime) to the GP2X, but I've come across a problem.

It requires the math libs for trig and the like. I would, if needs be, recompile it from source, but I can't seem to find the source .

Has anybody got math libs working, or simply the source of math so I can compile it?

Thanks in advance.

I find it very difficult to believe you've found a toolchain that doesn't come with libm, so I'm guessing you're not linking it correctly. You are using -lm aren't you?

Yes, I'm using -lm. DevKitGP2X doesn't appear to have a libm.a, and I don't have a math.h either. Help would be appreciated.

It's compiling now, as I've found all the libs. (just made it fall back on to the Dev-Cpp libs directory).

Unfortunately, I get loads of "[Warning] '__cdecl__' attribute directive ignored" errors then "[General Error] Too many messages; abort."

Help?

Hmmmm, so your mixing X86 libs and ARM libs, that is not going to work to well

you can use uclibc or newlib as standart library, they are both small and designed for embedded systems, for gp2x it's better then libc

Umm mine does. In 'sysroot/usr/lib' and 'sysroot/usr/include' respectively (both within the devkitGP2X directory.

You should have those and the compiler should pick up the header automatically. I don't want to ask a stupid question here but are you definitely compiling with 'arm-linux-gcc.exe'?
