After a lot of searching, i achieved to pass an amount of lists and put them to an array in programm.

Now i would like to know how to pass an array directly,without passing the lists of atoms..

void fingertips_list(t_fingertips *x, t_symbol *s, short argc, t_atom*argv);

void fingertips_perimeter(t_fingertips *x);

    c = class_new("fingertips", (method) fingertips_new, (method) NULL,

            sizeof(t_fingertips), 0L, A_GIMME, 0);

    post("fingertips object loaded...", 0);

    x = (t_fingertips *) object_alloc(fingertips_class);

        for (j = 0; j < 1000; j++) {

                image[i][j] = 1;

                image[i][j] = 0;

how-can-i-import-an-array-instead-of-lists

There are a few things that are very bad in your code ;-)

#1 you should declare this in your object structure otherwise those variable are shared by all the instances in your patch:

short image[1000][1000];
short perimeter[1000];
long points[5][2];
long imageWidth;
long imageHeight;


#2 your're calling outlet_anything on an inlet declared with intout

#3 the signature of your fingertips_new is wrong, as you declared the object as an A_GIMME (in your class_new call). It should be something like

void *fingertips_new(t_symbol *s, long argc, t_atom *argv)


I undersatnt that thare are some errors but my main concern is how to pass a matrix directly without passing lists of atoms...

This would be quite useful :)


The problem with the provided code is that i dont know what i have to put in my first struct and the main functions in the start and i believe that these parts are standards...

But now i think that your answer will be useful from here and on :)

Hi i tryed your code but i get this error undefined reference to `__imp___jit_sym_class_jit_matrix'

2. I dont understand what you mean by: ( Do not forget to link against the "JitterAPI.framework").

4. I pasted the code in flopMatrix.c into my code

1. I did include "jit-includes".
2. I dont understand what you mean by: ( Do not forget to link against the "JitterAPI.framework").
3. I use MaxSDK-6.0.4.
4. I pasted the code in flopMatrix.c into my code


I changed my SDK to SDK 5.1.7
but i still get errors


After trying hard i cannot resolve these spesific errors :( Any idea?? I really need help...

I wanna add that i m working with eclipse and not with XCode :)

the mistakes have decrased the main problem is not your code but libraries...

I think that the problem is the linker and that i dont know how to use XCode...

I would like to say that you have been very helpful and thank you a lot for your interest...

I m tottaly new in max development and cannot find information easily :(

how can i import an array instead of lists?
