Re: [Boost-users] MPFR in Boost 1.45.0

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

This is a GCC issue - the libraries being linked to must appear *after* the source files that need them. John.
