hi,

I just copied some c files from a unix machin to my ibook. After using installing xtools(which provided me gcc and gmake), I thought I was able to compile my program.
Unfortunately It gave the following errors

chundongchau$ make
gcc -o ../Run/boltzmann boltzmann.o -lm
/usr/bin/ld: boltzmann.o bad magic number (not a Mach-O file)
collect2: ld returned 1 exit status
make: *** [boltzmann] Error 1

How can I solve this?

I also tried to compile another file, but then it complained about the

-march=pentium

what do I have to type instead of pentium?

Thanks in advance

Well I believe that march would equal ppc (not pentium) for Mac use, but if you would post the actual makefiles themselves, it would be helpful to see what they are trying to do. The code might be trying to do a lot of platform specific stuff (otherwise I don't see why they would specify the arch).

It looks like maybe they're providing you with binary files (boltzmann.o) that the makefile is meant to link in, but the binaries are in the wrong executable format. Could that be the case?

It would be helpful to see the makefile.

okay guys, here you go...
Thanks in advance!!!



CC = gcc
CLINKER = gcc

CFLAGS = -Wall -O4 -g -march=pentium
LIBS = -lm
DEPEND= makedepend

SRC = boltzmann.c
OBJS = boltzmann.o
EXECS = boltzmann

default: boltzmann

all: $(EXECS)

boltzmann:$(OBJS)
$(CLINKER) $(OPTFLAGS) -o ../Run/boltzmann $(OBJS) $(LIBS)

clean:
/bin/rm -f *.o *~ $(EXECS)

.c.o:
$(CC) $(CFLAGS) -c $*.c

problem solved!

I deleted the .o file, which was generated on a linux machine and leaved out the -march parameter. It compiled fine...

thanks for the comments!
