Hi Frederico,

 I think I have all the other necessary requirements (Python and Numpy) but I 
 am not sure:
 - what version of the file I should download from 
 http://g.org/data/dev/ext/macos/pd/ . I am running on Mac OS X Snow 
 Leopard 10.6.8

start the terminal program and run the following commands:
- python —version“ - this will give you the version of your Python installation
- „which python“ will give you the location of your python installation

The major Python version is important: 2.5, 2.6. oder 2.7
and whether it is a system package (sitting in /usr/bin) or a user installed 
„local“ version (sitting in /Library/Frameworks/Python.framework)

That’s how you pick the py.pd_darwin-*.zip package. Unzip it and put it into 
pd’s extra folder.

 - where to locate the binaries to load in Pd-extended. I can only add paths 
 or startup flags but that hasn't worked—maybe I have the wrong file? I 
 include a screenshot of how my menu looks.
 

You’ll have to go to File/setup/startup flags and there add „-lib py

good luck,
gr~~~

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?

[PD] peek at a pd object's data

[Jonathan Wilkes via Pd-list]

If I have a t_gobj* for an object on a Pd canvas, and I know its size, 
how would I go about returning a list of bytes for that object's struct?


I'm sure this is nearly useless because of pointers and padding, but it 
might be fun.


Best,
Jonathan
