problem linking on MAC OSX

[amit hetawal]

Hello all,
I have a make file which looks like:
CC=/usr/bin/gcc
CPPFLAGS=-c -g -I/usr/local/Coral/include
-I/Users/hetawal/coral-3.7.5-public/custom
LDFLAGS=-L/usr/local/Coral/lib -lcoral -lpcap  -lhashtab -lz -lstdc++
OBJECTS=coral_test.o \
       recycle.o \
       lookupa.o \
       hashtab.o
TARGET=coral

$(TARGET): $(OBJECTS)
        $(CC) -g -o $(TARGET) $(OBJECTS) $(LDFLAGS)

coral_test.o: coral_test.c Makefile
        $(CC) $(CPPFLAGS) coral_test.c

clean:
        rm -rf $(OBJECTS) $(TARGET)

but its always giving me error as :
/usr/bin/gcc -c -g -I/usr/local/Coral/include
-I/Users/hetawal/coral-3.7.5-public/custom coral_test.c

/usr/bin/ld: Undefined symbols:
__Unwind_Resume
collect2: ld returned 1 exit status
make: *** [coral] Error 1

I have tried changing the compiler to g++ and the lstdc++ flag but no use.

Can someone help me with this ...

Thanks
