Try the libdir template:

http://puredata.info/docs/developer/MakefileTemplate/?searchterm=template%20...

Just copy that folder, rename it to your lib name, drop your externals
into it, add them to the makefile, then run "make". It'll
automatically build as universal i386/ppc. You could add x86_64 to it
easily enough.

I'm having trouble using xcode to compile an external (not audio,
pretty simple c code). Using Intel machine, OS 10.5, xcode 3.0; I followed the directions in : http://puredata.info/docs/developer/PdExternalsInXcode/ and it appears to compile cleanly. However, when I try to use the
external in a patch I get a dlopen error:

no suitable image found. Did find: ( ... the compiled external ... ): unknown file type, first eight
bytes: 0x21 0x3C 0x61 0x72 0x63 0x68 0x3E 0x0A

Has anyone found this error and/or a solution?

Failing that, could anyone share a robust makefile for building an
external that runs on both ppc and i386 using gcc? I tried that, but got "Undefined symbols" errors for all the pd
classes (perhaps it's not finding m_pd.h, but I thought I set the
path carefully enough...)

Many thanks for any help!
