[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'*
I've tried declaring the setup function as C code like Katja explains on
her site http://www.katjaas.nl/pitchshift/soundtouch~.html:
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
threadhttp://lists.puredata.info/pipermail/pd-list/2002-02/004485.html
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

Re: [PD] wacom digitizer 2 tablet - pd
hi johannes, that's a bit OT, but i once had a huge and old serial wacom to play with. - i tried to use it with a serial to usb interface and that interface worked but the drivers for the tablet were only for PPC or even os 9, so there was no way getting it to work on os x. linux or windows might be a different story. a new simple tablet is around 70,- euro and spending a day trying to get it to work was definitely not worth it. max Am 24.04.2012 um 20:45 schrieb johannes: hello hans, no, its a serial port. before buying an adapter i just wanted to know if it would work and how the digitizer2 would work in pd in comparrison to newer models. as far as i know the digitizer was build in 1992 and was not cheap at all… but i can be wrong. thanks, johannes Am 24.04.12 15:48, schrieb Hans-Christoph Steiner: If its USB, it worth messing with.

Re: [PD] [Pd] Compile external with C++ compiler?
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

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'
I've tried declaring the setup function as C code like Katja explains on her
site:
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

Re: [PD] [Pd] Compile external with C++ compiler?
Hi guys
The part that I don't get is how to call C functions from C++? I don't
think I've even tried that before. Have you?
Joe: I've built externals that just call C++ functions that I declared
with extern C or wrote wrapper functions to export a C-callable
public interface to C++ functions. Best suggestion I've got is to
identify which functions you've got are going to be public and which
ones are private and plan out how you're going to declare them.
