GP32 I cannot sin! (or cos or tan...)

[DuderJace]

Hello! I downloaded the ready set-up environment from www.thaworx.co.uk/ninja,
I've done a few really simple programs just to check i remembered how to code. They all worked okay until I tried one using math.h and the sine / cosine etc. stuff. It kept saying 'undefined function sin ....' I know the processor doesn't do floating point math/division and things, but that shouldn't have any effect on programming in c should it?
Thanks for any help. Jace.

You remembered to add "-lm" to the linker aswell?

Why dont you try to use a sin table, i have one on my site, it was donated to me by mithris. but i have made extra functions in it.

Sorry there it was groapaz's sin table!!

Easier to use the functions for new coders (or to start with). Sine tables are for the optimizers.

I'm using the Makefile that was included, it says that it isn't doing linking. Seems a bit strange.
I might have a go at using a table instead. It would be a lot quicker.
