well, hi, progressing with C++ as always, just got to the SDL part, but found that my application doesn't work in the exact same way between my main pc and the gp2x.
The quiestion is: is it a bug in the HWAcc SDL library, maybe someting to do with the 940, or is it a bug in tha compiler?
The commands line
used -msoft-float because the main cpu doesn't have a fpu does it?
btw, using code:blocks, and lastest open2x sdk and libpack with lastest HWAcc SDL.
images:

NOTE: the higher the precision (smaller the numbre is more), the more dots appear, i presume it has something to do with the fpu emu
PD: unrelated but i have a problem with the hwacc sdl, when trying to use any of the gp2x's especific sdl functions (SDL_gp2x.h), the linker throws me the blablabla undefined error. maybe i have something missconfigured?
PPD: if you need the source code tell me and i'll upload it
