Hi Michael.

When compiling for MacOSX, I started out using the makefile for expr~ as
my model.
There are a few refinements that have evolved. A linux makefile will
typically get you 95% of the way there.
The final 5% is best done by example, as I just learned this stuff
empirically:

LINUXCFLAGS = -DPD -DUNIX -O6 -funroll-loops -fomit-frame-pointer \
    -Wall -W -Wshadow -Wstrict-prototypes -Werror \
    -Wno-unused -Wno-parentheses -Wno-switch

would translate to:

MACOSXCFLAGS = -DPD -DUNIX -DMACOSX -O3 \
    -Wall -W -Wstrict-prototypes \
    -Wno-unused -Wno-parentheses -Wno-switch

and...

LINUXLDFLAGS = -export_dynamic  -shared 

MACOSXLDFLAGS = -bundle -bundle_loader /path/to/pd/bin/pd -flat_namespace

(often you will find "-undefined suppress" in the place of "-
bundle_loader", but explicitly telling the linker about Pd's symbols is
better.)

Hope that's some help.

I'd love to make this a non-issue for most externals, and offer them pre-
compiled, but it's hard to figure out how to package them so that a
user's installation is trivial.

cheers,
adam
