GBDK: can't use malloc

Hi,

I am developping on game boy with GBDK 2.95.3, but I can't find any way to use malloc. Malloc.h has no definition for malloc function, but  the function is declared in Malloc.c.

I don't understant what I am supposed to do to use malloc with gbdk.

Anyone has any idea ?

Thanks a lot.

Re: GBDK: can't use malloc

Given the GB has very little memory, I would discourage the use of malloc altogether.
I never used GBDK, anyways, so I can't help you with that.

Re: GBDK: can't use malloc

I underdstand it, in fact I wish to use malloc to avoid declaring an array of a specific size when I can have a smaller array in some cases. But I think I will change my design and keep some constraints, it will be better for memory space.

I used GBDK a lot, and I ended up using fixed size arrays, anyway it is a GB, and it's better to simplify things a lot, you probably can do without malloc just fine.

Re: GBDK: can't use malloc

Yes, I have given up and just used a fixed size array. It was for sprite animation, so I decided to force animations to have 2 frames only, it will be enough on Gameboy. Thanks at all for your advices.
