Malloc and similar function usage 2 Months ago Karma: 0

Hi guys,
I'd like to use the dinamic memory assignment function (malloc, realloc) on the dsPIC33FJ256MC710 and when I use them I get a compile error:

Code: :


 
A heap is required, but has not been specified

I think I've to redefine the .oil file adding the heap properties but I'nt know how. Can someone give me some help?
Cheers, MARCO

It's easy.
As you said you have to specify the heap using the C30 option --heap= and this can me done in the .oil adding the LDFLAGS attribute as described below.

Code: :


 
CPU mySystem {
    OS myOs {
        EE_OPT = "DEBUG";        
        CFLAGS = "";
                LDFLAGS = "--heap=1024"
                
    };
        
};
