[PD] Compile a Pd external error

[Fanouris Moraitis]

Hi,

I am trying to compile the simple helloworld from your tutorial on how
to write pd externals.

The only thing that I changed is the path for my m_pd.h

I have the following error when i do gcc helloworld.c


/usr/bin/ld: Undefined symbols:
_main
_class_addbang
_class_new
_gensym
_pd_new
_post
collect2: ld returned 1 exit status

do I have to add some options to the gcc?
(I am working on Os x 10.4.7 and I have a precompiled version for pd extended)

thanks,
fanouris
