instead of -opowder, use -o powder.

Might work, if not, just remove the whole -opowder thing.

There is one error, the gcc option error at the bottom.

Ok, I fixed the -o option and this is the readout now:

It looks like I'm going to have to change the header names in the -l options to absolute paths.

Nope, it is a common path problem

./ <- windows file system

/ <- unix file system

Although seeing as the powder toy is cross compilable I think this would have already been done. Maybe absolute is the only way.

Does anyone know what the -l flags are for? I am almost tempted to remove them because I'm not sure what their purpose is and, while I know (or think I know) what -lSDL and -lbz2 reference, I have no clue what -lm references.

They are instructions to ld.

Could you explain in a little more detail please? You'll have to forgive me for not completely understanding, most of my coding work is in Python and web languages, so I don't typically mess with compilers much.

@Excimer-Sun-Software
just a question, how much ram does your ipod have?

They are instruction to the linker.

Oh ok.How necessary are they?(quite very, yes?)

Very very indeed yes.
