Ah, yes, I see now. 

I solved it by adding:

 x->x_canvas = canvas_getcurrent();

in _new

thanks!

It's hard to say without seeing the code.

Does x->x_canvas actually point to a canvas?  The error seems to be telling you it isn't.

(Consistency check errors come from the bug() function.  Generally they occur when an argument, struct, or struct field is checked for existence and fails that check.)

Yes, 

in the main struct x_canvas is created as:

t_canvas *x_canvas;

So, I think that is not the problem.

Well, it expects a t_canvas *, so if you send it something else it will trigger the error.

Hi all,

I am trying to use the canvas_makefilename() function in g_canvas.c

I am calling it like this:

static void lilypond_write(t_lilypond *x, t_symbol *s) {
    char buf[MAXPDSTRING];
    canvas_makefilename(x->x_canvas, s->s_name, buf, MAXPDSTRING);
}

but when I send the object a message such as [write test.txt( or similar, I get:

error: consistency check failed: canvas_getenv
Bus error: 10

The method is set up like this:
    class_addmethod(lilypond_class, (t_method)lilypond_write, gensym("write"), A_SYMBOL, 0);

Anybody has any suggestion?

best,

J

PS Sorry for pestering everyone with this, but there is little documentation on some of the functions in Pd. Perhaps this thread belong in the Pd-Dev list?
