Yes, you're right. The object file is compiled ok:
g++ -I/path/to/boost_1_45_0 -lgmpfrxx -lmpfr -lgmpxx -lgmp -c boost_mpfr_example.cpp
but linking fails in building the executable:
g++ -I/path/to/boost_1_45_0 -lgmpfrxx -lmpfr -lgmpxx -lgmp boost_mpfr_example.o -o boost_mpfr_example
Actually, simply including <boost/math/bindings/mpfr.hpp> gives the following three errors (i.e. commented out the contents of main):
boost_mpfr_example.o: In function `MpFrC::get_base()':
boost_mpfr_example.cpp:(.text._ZN5MpFrC8get_baseEv[MpFrC::get_base()]+0x6): undefined reference to `MpFrC::base'

I have MPFR 3.0.0-2 (ubuntu packages: libmpfr-dev, libmpfr4), gmp 4.3.2 (libgmp3-dev, libgmp3c2, libgmpxx4ldbl), and gmpfrxx (http://math.berkeley.edu/~wilken/code/gmpfrxx/). I note that gmpfrxx was "Last updated 2008/11/16 to incorporate new features of MPFR 2.3.*"
Has anyone got MPFR 3.0.0 working with boost 1.45.0 and if so, what was your setup?
cheers,
Novak.
