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:

http://alberto.zin.googlepages.com/mingwtutorial

worked preatty well! thanx Alberto!

He linked to this guy:

http://www.sarc.qub.ac.uk/%7Eelyon/LyonSoftware/Pd/

(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!

Hey, nice to see that the page on compiling externals was useful

cheers,

AlbertoZ

this is the simplest way to compile externals on osx 10.5 and pd-0.41-4
(really rude method)

• install Xcode

• write your external.c or find one already done

• open finder -> applications -> pd-package. open package.
  Then go to Resources -> extra.
  there are some built in externals folders
  -make a copy of one of these folders and rename the same as your external.
  -inside this folder delete all the files except the makefile and copy your external.c there.
  -open the makefile and rewrite the fields NAME and CSYM with the name of your external (if sou wrote a tilde external -> see one of the built in as fiddle~)
  Save

• ok, now come back to "extra" folder, open makefile and change at first row "pd_linux" with "d_fat"
  Save

• open terminal and type:
  cd /Applications/Pd-0.41-4.app/Contents/Resources/extra/your-external
  make

• copy the external in "extra" folder or where it needs
  it's done.

Hi, I tried Icoon's and Enrico's methodes but it doesn't work.

I copied the code from Johannes (helloworld) in a new C file in XCode. Then I did what enrico explains ; but when I type "make", the terminal answers a lot of errors. I probably forgot something, but what?

okay... The problem was that m_pd.h was not recognized. Il put a copy of it in the same folder and it works.
