Re: [PD] Successfully compiled Mac OS X Intel externals

Hi,

I'm sorry but at present time our MacBook is away so I can't try it out.

I'd like to build universal binaries in the near future but I have to study Apple's documentation about them... It should be pretty simple: compile 2 kind of file object (one with the -arch i386 flag and the other with ppc) and them merge them at linking time. If I'm not wrong, the makefiles provided with Pd 0.40 for Mac OS X 10.4, do exactly that.

Best, Stefano

Is the -arch required? Could you build a native build by omitting the -arch flag? How about building fat binaries?

It looks to me that the only thing different from the old style is the -arch flag.

Hi all,

it seems that some people still have doubts about building externals for Mac OS X... so, last week I successfully compiled a few externals for Mac OS X Intel and PPC. Here are the important parts from one of my makefiles (Intel Mac):

MACOSXCFLAGS = -DMACOSX -DPD

OPTIM = -O2 PARANOID = -Wall -W -Wstrict-prototypes
-Wno-unused -Wno-parentheses -Wno-switch

MACOSXSOUNDINCLUDE = -I$(RESOS)/modal_object -I$(RESOS)/ waveguide_object -I$(RESOS)/inertial_object
-I$(INTERS)/impact_interactor -I$(INTERS)/linpact_interactor -I$(INTERS)/friction_interactor

CFLAGS = $(MACOSXCFLAGS) $(MACOSXINCLUDE) $(MACOSXSOUNDINCLUDE) $ (OPTIM) $(PARANOID)

TARGET = friction_2modalb~

OBJ = friction_interactor.o modal_obj_b.o matrix_calc.o

all: $(TARGET).pd_darwin install

$(TARGET).pd_darwin: $(TARGET).o $(OBJ) cd $(OBJDIR) ;
$(CC) -arch i386 -bundle -undefined suppress -flat_namespace
-o $(TARGET).pd_darwin $(TARGET).o $(OBJ) -lm

$(TARGET).o: $(TARGET).c
pd_modules.h
friction_interactor.h
modal_obj_b.h
matrix_calc.h

install: -strip -x $(OBJDIR)/$(TARGET).pd_darwin -mv $(OBJDIR)/$(TARGET).pd_darwin $(MACOSXBINDIR)

%.o: %.c
pd_modules.h [ -d $(TOP)/obj_macosx ] || mkdir $(TOP)/obj_macosx $(CC) -g $(CFLAGS) -c -o $(OBJDIR)/$@ $<

and to compile on a G4 I just changed -arch i386 to -arch ppc. They work great!

Hope this helps.

Greetings, Stefano
