Trying to build the LEVMAR math library on a mac using the Accelerate Framework

Question

I want build levmar-2.5 math library on a mac using the included Makefile. It requires LAPACK,
another math library which is included in the Accelerate Framework. I do

Answer 1

For reference, here's the makefile that will work:

#
# Unix/Linux GCC Makefile for Levenberg - Marquardt minimization
# Under windows, use Makefile.vc for MSVC
#

CC=gcc
CONFIGFLAGS=#-ULINSOLVERS_RETAIN_MEMORY
#ARCHFLAGS=-march=pentium4 # YOU MIGHT WANT TO UNCOMMENT THIS FOR P4
CFLAGS=$(CONFIGFLAGS) $(ARCHFLAGS) -O3 -funroll-loops -Wall #-ffast-math #-pg
#LAPACKLIBS_PATH=/usr/local/lib # WHEN USING LAPACK, CHANGE THIS TO WHERE YOUR COMPILED LIBS ARE!
LDFLAGS=-L. # for non-OSX, add: -L$(LAPACKLIBS)
LIBOBJS=lm.o Axb.o misc.o lmlec.o lmbc.o lmblec.o lmbleic.o
LIBSRCS=lm.c Axb.c misc.c lmlec.c lmbc.c lmblec.c lmbleic.c
DEMOBJS=lmdemo.o
DEMOSRCS=lmdemo.c
AR=ar
RANLIB=ranlib

LAPACKLIBS=-framework Accelerate #This works for OSX where the SDK is installed.

LIBS=$(LAPACKLIBS)

all: liblevmar.a lmdemo

liblevmar.a: $(LIBOBJS)
    $(AR) crv liblevmar.a $(LIBOBJS)
    $(RANLIB) liblevmar.a

lmdemo: $(DEMOBJS) liblevmar.a
    $(CC) $(LDFLAGS) $(DEMOBJS) -o lmdemo -llevmar $(LIBS) -lm

lm.o: lm.c lm_core.c levmar.h misc.h compiler.h
Axb.o: Axb.c Axb_core.c levmar.h misc.h
misc.o: misc.c misc_core.c levmar.h misc.h
lmlec.o: lmlec.c lmlec_core.c levmar.h misc.h
lmbc.o: lmbc.c lmbc_core.c levmar.h misc.h compiler.h
lmblec.o: lmblec.c lmblec_core.c levmar.h misc.h
lmbleic.o: lmbleic.c lmbleic_core.c levmar.h misc.h

lmdemo.o: levmar.h

clean:
    @rm -f $(LIBOBJS) $(DEMOBJS)

cleanall: clean
    @rm -f lmdemo
    @rm -f liblevmar.a

depend:
    makedepend -f Makefile $(LIBSRCS) $(DEMOSRCS)

# DO NOT DELETE THIS LINE -- make depend depends on it.

You need to pass -framework Accelerate to gcc. You also need to#include <Accelerate/Accelerate.h>. Details are here.
