• in the helloworld example, the fact that I called it main while the code itself referred to helloworld
• in my own code (the one I had trouble with in the first place) ..no bloody idea

maybe the fact I cleaned all the remaining main.pd_linux on the file system solved the issue

anyway , hail to "LD_DEBUG=libs ..."

@seb-harmonik.ar just edited, ... again ...:-)

now, my own code works just fine without modif, jee what the hell

anyway, I finaly found a way to debug PD library loading

I removed all other instances of my main library I found on my drive, now I only get 1 "succeeded"

I updated pd

sudo apt-get install --only-upgrade pd

I used **pd-lib-builder **make file

same story

I found a way to debug library loading:

LD_DEBUG=libs /usr/bin/pd

...

      7840: calling init: /usr/local/lib/pd-externals/main/main.pd_linux
      7840: 
      7840: /usr/local/lib/pd-externals/main/main.pd_linux: error: symbol lookup error: undefined symbol: main_setup (fatal)
      7840: /usr/local/lib/pd-externals/main/main.pd_linux: error: symbol lookup error: undefined symbol: setup (fatal)

fixed the code and...YES

hope this also helps anyone stumbling upon this sort of issues

maybe I ran a package update at some time....

as stated above, I used a simpler "hello world" code, same issue

here is the code

#include "m_pd.h"

static t_class *helloworld_class;

typedef struct _helloworld {
  t_object  x_obj;
} t_helloworld;

void helloworld_bang(t_helloworld *x)
{
  post("Hello world !!");
}

void *helloworld_new(void)
{
  t_helloworld *x = (t_helloworld *)pd_new(helloworld_class);

  return (void *)x;
}

void helloworld_setup(void) {
  helloworld_class = class_new(gensym("helloworld"),
        (t_newmethod)helloworld_new,
        0, sizeof(t_helloworld),
        CLASS_DEFAULT, 0);
  class_addbang(helloworld_class, helloworld_bang);
}

here is the make file

    $(info /usr/lib/puredata/extra/main/main.pd_linux)

no I just did not paste the zillion paths pd tried to open

https://github.com/pure-data/externals-howto

I dont thin the code is the issue since I tried mine and this one
I'll restart the raspberry pi

no idea..and it was working for a while....

the problem is that pd complains but is not really constructive on the verbose level

also my plugin is supposed to write stuffs in the syslog, cant find anything

I used a helloworld example, same thing...wtf...

Hello,

I wrote an external a while ago and now I cant load it anymore
it's on a respberry pi, so I did not change anything about the setup nor the version of puredata nor reinstall the box

I noticed something strange is happening, in verbose mode, it tries tons of different paths, then says it can find the external (2 times) but then it fails to create it

how can I solve/debug this ?

regards

Hello,

I fiddled around with clipping, but, does anyone knows how to create this sound in puredata ?

thanks guys, I'll have a look at these
