问题
I am trying to compile a program from
https://github.com/davidsd/sdpb
with gcc-4.9, boost 1.57.0, gmp-6.0.0a, and mpfr-3.1.2 on OS X 10.10.2, but I keep getting errors seemingly related to the gmp and mpfr packages. I know somebody who successfully compiled on 10.9.5. Can anybody suggest a fix?

Looks like the ordering is wrong. The libraries should follow the object files

It linked without error on my system
So in the Makefile, change the link command to
$(RESULT): $(OBJECTS)
$(CC) $(CFLAGS) -o $@ $^ $(LIBS)
