Invalid call of undeclared identifier 'texture2DRect'

[cansik]

When I try to run this simple sketch with Processing 3.0.1, I always get this error message when trying to get the image. It doesn't matter if I use getGraphics or getImage.

Sketch

import codeanticode.syphon.SyphonClient;

SyphonClient client;
PGraphics img;

void setup()
{
  size(500, 500, P3D);
  client = new SyphonClient(this, "Simple Server");
}

void draw()
{
  if(client.active())
  {
    img = client.getGraphics(img);
    image(img, 0, 0, width, height);
  }
}

Am I doing something wrong or is it a bug?

Unfortunately there's no core-profile support yet, see #25

void settings() {
    // ...
    PGJOL.profile = 1;
}

closing as dup #25

Just out of interest, the cause of this particular error is a bug in Processing processing/processing#4810 I'm sure that isn't the only issue with core-profile support 😄 Although I had read something that would suggest a client might work?

FWIW - my students were perplexed by why the suggested line above by bangnoise is wrong. There is a typo, and it should read:

void settings() {
    // ...
    PJOGL.profile = 1;
}

Hope this helps others.

Core Profile support is here now - that line is no longer required. Update/install the Syphon library from within Processing using the Contribution Manager (Sketch > Import Library... > Add Library...).

Ah ok. Great - thanks.
