Hi Joe,
Have you thought of using ofxPd?
I'm involved in the creation of an app for the iPhone right now, and we're using ofxPd from Dan Wilcox:
https://github.com/danomatika/ofxPd
Since Openframeworks is a bunch of C++ wrappers for various libraries, ofxPd adds Pd to the libraries that you can work with in C++.
Then you can call the setup function within the xcode build, and your object will work in libpd (i.e. ofxPd) in the app environment.
Bear in mind that Apple do not like GnuGPL licensed stuff, so I've created BSD licensed versions of some of my own Pd externals for this project.
And the
app works. We're in the final stages now, so I'll post to the list when it's complete!
Best,
Ed

Subject: [PD] [Pd] Compile external with C++ compiler?
Hi all,
Thought I might as well ask this here
because you guys know everything :)
I'm writing an external to be built into an iOS app that's running Pd. The catch is I need to interface with a C++ library within the external.
The external builds and runs fine if I'm using the C compiler (in Xcode) but I can't access the C++ library functions. If I switch it to compile in C++ (by changing the objective-c file from .m to .mm) then I can use the C++ library functions but it complains that it can't find 'class_addmethod'
'No matching function for call to 'class_addmethod'
extern "C" void external_tilde_setup(void) { }
But that still didn't seem to work. I was also going through the list and found
this thread but I'm not sure if it's the right approach. Plus I'm more of an audio guy than programmer :)
Any ideas would be much appreciated.
Thanks,
Joe
