Apologies - I'm trying to do this while buying a house...I don't know if that
is simple in Austria but it isn't here.
But, I was indeed firing blind myself. I assume you are referring to line 665
to 668 in mbc_lpc~.c:
mbc_lpc_class = class_new(gensym("mbc_lpc~"),
(t_newmethod)lpc_new,
0, sizeof(t_lpc),
CLASS_DEFAULT, A_DEFFLOAT, 0);
After reading your email I assumed it was something new, but of course I had
just copied, pasted and altered code from a previous external (and forgot)
Perhaps it's to do with linking to libm, so I'll check the makefile once I'm
back in a reasonably stable (time-wise) environment.
BUT - I've never really understood (in ~13 years of external development) what
all those args to class_new() did before, and you've forced me to look deeper
into m_pd.h
I should thank you for that - and yes, I learned how to write externals by
reading your howto, in 2005 I believe.
Thanks,
Ed

hmm... each and every one?
just to make sure: with "external" you mean some dynamically loadable
file that somehow adds new [object]s to Pd?
if we can agree on that, you might want to read my externals howto [1].
(for completeness sake, there are other ways to write externals; but so
far the only thing i've understood so far is that "it doesn't work",
making it impossible to tell which path you took before you lost your way).
