BTW, you are using a very old gcc compiler, couse the new ones say before every line, if it is a warning or an error. use the -w or -Wall switch to figure it better out.

Thanks. I managed to figure out that the -fshort enums was making the error
c:/devkitadv/arm-agb-elf/include/SDL/SDL_types.h:101: size of array `SDL_dummy_enum' is negative

and in flash.h byte is used as a variable but it is also a type representing 8 bits

After fixing this and other problems, I get to the end and there are many linker problems regarding hard-float and soft-float. (There were also many problems with interworking but these were warnings so Iguess its OK)It looks like the libraries I got from the web were compiled with hard-float and the compiler I got (devkitadv 5 beta) makes only soft float(makes no difference if I have specified -mhard-float in the makefile)
