Hi, I cc'd this to pd-dev pd-dev@iem.kug.ac.at because that's the new list for this kind of questions.

I want to make a pd-external which makes use of a library which needs C++. I'm a newbie in writing PD externals. I'm using a SGI IRIX 6 system.

I use the standard makefile which comes with the pd Foo examples. .

When I change the "cc" in the makefile to "CC" my c++ lib compiles but m_pd.h generates the following error 12 times: " A storage class cannot be specified at this point" EXTERN_STRUCT _clock;

Anyone have any ideas about this?

No, not exactly, but I had to solve similar problems when I ported the dx7 emulator rx-saturno to a PD external (see footils.org). rx-saturno is written in C++, so maybe I have some tips. First I read the Usenet-FAQ on "Howto Mix C and C++" somewhere, that's of help, search google for it.

Basically what's needed is: You should use the same compiler for all sources involved.

You should define the external's setup function as: extern "C" void something_setup(void)

After I discovered flext at http://www.parasitaere-kapazitaeten.net/Pd/ext I wrote most of my externaly directly in C++.
