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?

yes, since gcc will by default produce an executable, which is not what you want.

...

(I am working on Os x 10.4.7 and I have a precompiled version for pd extended)

there are makefiles for the examples in http://pure-data.cvs.sourceforge.net/pure-data/doc/tutorials/externals-howto...
