Hello! I want to install boost.mpi on my ubuntu. Using the synaptic I have installed boost 1.35, boost-build and bjam to follow the instructions of http://www.boost.org/doc/libs/1_37_0/doc/html/mpi/getting_started.html#mpi.c... They say that I should run "bjam --with-mpi" in the top-level boost directory, but it is not clear for me where is this directory. I try to run this command in every directory where it was something about boost but it didnot work. /usr/include /usr/share/boost-build /usr/share/boost-build/tools The error message that I obtain is: error: no Jamfile in current directory found I have tried to do the same in another computer and in this case I have installed manually boost 1.37 and here it is working. Do you know what is the problem? boost 1.35 supports boost.mpi? Do I need to download boost manually? Thank you very much.
