Hi,

I managed to compile the helloworld external demo by:

http://iem.at/pd/externals-HOWTO/node3.html

on OSX!

I want to share with you!

First I tried on pc with Cygwin and gcc,gdb,make installed.
I found the solution here:

worked preatty well! thanx Alberto!

(btw goood externals here!)

Here I found a good makefile for osx and I hacked the
shell commands out.

Here the commands:

For OSX you need:

Terminal
Xcode with gcc & company installed.

open terminal
go to your code directory (helloworld.c)

then type:

cc -DPD -O2 -Wall -W -Wshadow -Wstrict-prototypes -Wno-unused -Wno-parentheses -Wno-switch -I ./ -o helloworld.o -c helloworld.c

cc -bundle -undefined suppress -flat_namespace -o helloworld.pd_darwin helloworld.o

then copy the helloworld.pd_darwin to the externals directory (i.e. Pd-0.39.2-extended.app/contents/resources/extra , its in the package content!)

start pd
make object helloworld
bang the input
read Hello World!! in the command window.

enjoy!
