Hi, Thanks for reply. I didnot find any libboost_graph_parallel in the installed directory. I found only the following when I gave ls libboost_mpi.a libboost_mpi.so.1.41.0 libboost_serialization.so libboost_mpi.so libboost_serialization.a libboost_serialization.so.1.41.0 Is it not that all are linked together in libboost_mpi.a ? I am still not able to figure out how to run the tests in the libs/graph_parallel/test directory. Any ideas ? Thanks, Praga. On Wed, Nov 25, 2009 at 10:33 AM, Jeremiah Willcock wrote:

--with-mpi install --prefix=somepath in the BOOST home directory. I am not sure whether this is enough to get the parallel graph library also compiled. How can I verfity whether my parallel graph library also compiled ? If it is compiled how to run the test programs given the test directory ?

Can anybody give me some directions on this ?

It should be compiled if Boost.MPI is. Look for a libboost_graph_parallel* library in your installed lib directory to be sure.

Sorry -- I forgot that --with-mpi turned off all other libraries. Try adding --with-graph_parallel to your build line.

There should be a libboost_graph_parallel.a; the parallel graph stuff should not be in libboost_mpi.a. When you link your code, you need the libraries you listed plus -lboost_system and -lboost_graph_parallel.

Do you get the warning about MPI not being found? Does your libboost_mpi.{a,so} contain any symbols (use nm -D on the .so file)? Which lib directory are you looking in? The one in ~/bin/boostpath/lib? I'm just checking the "obvious" things to look for simple problems first.

Hi praga, praga wrote:

Have you set your $LD_LIBRARY_PATH environment variable? I haven't installed 1.41, but for v1.40, I added /usr/local/boost_1_40_0/lib to the search path. As for an earlier e-mail of your's, in terms of boost installation, one thing that I did which was different was that I added "using mpi ;" to the end of my project-config.jam file before running bjam. I don't know if it is necessary; it's something I did for an older version of boost a while back and haven't bothered to check if it's still needed... Ray

You need to add -lboost_system to the end of your compile command. FWIW, the following might be of general help when dealing with linker errors: http://vladimir_prus.blogspot.com/2009/06/linking-101.html

adjlist_build_test.cpp:(.text+0x2076): undefined reference to `boost::graph::distributed::communicator(boost::graph::distributed::mpi_process_group const&)'

Hopefully, given the above suggestions and the URL, you will be able to figure what do do about this linker error, too. - Volodya

It would be better if you explicitly say so, rather then omitting those libraries and reporting the expected linker errors you get.

So whenever I try to include libraries such as libboost_system or libboost_graph_parallel I am getting errors that those libraries are not found.

I compiled the BOOST using bjam --with-mpi --with-graph_parallel and installed using command bjam --with-mpi --with-graph_parallel install --prefix=~/bin/boostpath

I remember seeing the parallel graph libraries while installing in the command line but I am not sure why they are not there in the installed path.

Could you please run the following command in the root of your Boost source tree: bjam --with-mpi --with-graph_parallel --prefix=/tmp/boost install > log 2>&1 and then run this command: ls /tmp/boost > log and then archive and post the 'log' file? Please run the commands exactly as written -- in fact, just copy paste them in your terminal. - Volodya

I did a guess work of including --with-system along with other --with-XXX while installing and this proved correct. Thanks for all for helping me. So finally if we have to install boost graph parallel library we need to use the following command bjam --with-mpi --with-graph_parallel --with-system --prefix=Installdir install Thanks, Praga.
