Cannot compile boost mpi example
I have downloaded boost 1.43 and run many of the examples without a problem. However, I am not able to compile any of the parallel graph examples. I traced the problem to using boost MPI. For example when I compile the first example in: http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/tutorial.html I get: /tmp/ccwOi38z.o(.text+0x132): In function `main': : undefined reference to `boost::mpi::environment::environment(int&, char**&, bool)' /tmp/ccwOi38z.o(.text+0x13b): In function `main': : undefined reference to `boost::mpi::communicator::communicator()' /tmp/ccwOi38z.o(.text+0x144): In function `main': : undefined reference to `boost::mpi::communicator::size() const' /tmp/ccwOi38z.o(.text+0x150): In function `main': : undefined reference to `boost::mpi::communicator::rank() const' /tmp/ccwOi38z.o(.text+0x1b1): In function `main': : undefined reference to `boost::mpi::environment::~environment()' /tmp/ccwOi38z.o(.text+0x1e2): In function `main': : undefined reference to `boost::mpi::environment::~environment()' MPI works fine as I have tested with the example in: http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.m... I am running linux 64 bits, gcc 3.4. Thanks in advance, Hernan

I'd guess you're not linking against the Boost.MPI library. Are you sure you've built the library and are you linking against it? http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.i... -- Noel
Hi,
Thanks for the response. This is a little bit confusing to me. According to:
http://www.boost.org/doc/libs/1_43_0/more/getting_started/unix-variants.html
I do not need to build BOOST.MPI. I thought Boost.MPI was a header only library.
Thanks,
Hernan

Erm, yeah, no. MPI need to be built and is one of those that need to be explicitly asked for to be built as well. Have a look at the individual library docs. http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.i... KTC

It isn't the page is a little out of date. C:\boost\trunk>bjam --show-libraries The following libraries require building: - date_time - filesystem - graph - graph_parallel - iostreams - math - mpi - program_options - python - random - regex - serialization - signals - system - test - thread - wave In Christ, Steven Watanabe
