Hi everyone i’m new in processing so i don’t know how to fix this problem. At the moment im working on a project which take a photo via webcam. The trigger for the photo is the detection of a smiling person. I tried to work with this “psmile.psmile” library, but i can’t start the sketch. Whenever i try i get the error:
A library relies on native code that’s not available.
Or only works properly when the sketch is run as a 32-bit application.
UnsatisfiedLinkError: C:\Users\PC\Desktop\Smile002\code\PSmile.dll: Can’t load IA 32-bit .dll on a AMD 64-bit platform.
Is there still a way to run this sketch on my laptop?
I’m thankful for every help and sorry for the bad english.

Were you able to resolve this issue?
Where did you get the PSmile library, and how did you install it? What specific version of Processing are you using it with?

I couldn’t resolve this problem and I got the library here: [http://www.magicandlove.com/blog/research/smile-detection-library-for-processing/](http://www.magicandlove.com/blog/research/smile-detection-library-for-processing/).
The Version i’m using is 3.5.3.

Well, if that is PSmile 1.1.0, then it looks like it was compiled for Processing 2.0b3.

You could try building the library yourself on your platform from source:

You will probably (?) need to update it to get it working with Processing 3.

Hi @Ten,
Another solution could be to _train_ your camera to detect a smile.That [thread](https://discourse.processing.org/t/how-do-i-make-my-webcam-detect-a-pose-i-make/990/2) could probably be of interest to you.
