I attempted to integrate the C++ freeverb~ external that I found in Perry Cook's Synthesis Toolkit, following Peter Brinkmann's model of fiddle_tilde_setup(), and thus using freeverb_tilde_setup(), but this did not work. Can anyone tell me if this is possible?

Thanks

Hey, just wanted to say thanks for making me google perry cook's stk. But if I can find some more info on brinkmann's model I'd be glad to try and figure it out.

Hi Monetus.Thanks for checking in. in case it's not clear, I'm working with libpd within Xcode and iOS, using Objective-C. Here's the relevant website:

https://github.com/libpd/pd-for-ios/wiki/ios

In his book, Making Musical Apps, Brinkmann describes how he incorporates externals into this environment, which is otherwise based on Pd Vanilla. You basically need to drag the .c file into the project, make a declaration in the ViewController.m file:

 void fiddle_tilde_setup();

And then call the function after PdBase and PdDispatcher have been set up:

 fiddle_tilde_setup();

This works fine for externals written in C.

(Note that working with references to C++ code requires changing the view controller to a .mm file. Also, I did find a freeverb~ written in C:

https://svn.xiph.org/trunk/postfish/freeverb.c

but it seems to depend on entire other framework, and it wasn't clear to me that this was going to work or be worth the time.)

Hi there, did you ever end up getting this to work? I'm trying to integrate helmholtz~ into a libpd project as well, and I'm having trouble either building it as part of the libpd library (doesn't like .cpp files in the project), or including it in my Objective-C++ app.

Never mind, just a bit more searching and I found the proper way to do it from this part in the documentation:

https://github.com/libpd/libpd/wiki/Adding-Pure-Data-external-libraries-to-your-project

The big difference being that you have to forward declare the setup function a bit differently for c++, you have to do it like this:

extern "C" {
    void helmholtz_tilde_setup();
}
