    text
    copied!<p>For this simple code (taken from the boost-mpi documentation):</p> <pre><code>#include &lt;boost/serialization/string.hpp&gt; #include &lt;iostream&gt; #include &lt;string&gt; #include &lt;boost/mpi.hpp&gt; namespace mpi = boost::mpi; int main(int argc, char *argv[]) { mpi::environment env(argc, argv); mpi::communicator world; if (world.rank() == 0) { world.send(1, 0, std::string("Hello")); std::string msg; world.recv(1, 1, msg); std::cout &lt;&lt; msg &lt;&lt; "!" &lt;&lt; std::endl; } else if (world.rank() == 1) { std::string msg; world.recv(0, 0, msg); std::cout &lt;&lt; msg &lt;&lt; ", "; std::cout.flush(); world.send(0, 1, std::string("world")); }; return 0; }; </code></pre> <p>And for such CMakeLists.txt:</p> <pre><code>CMAKE_MINIMUM_REQUIRED(VERSION 2.6) PROJECT(mpi-tests CXX) FIND_PACKAGE(Boost 1.4 COMPONENTS mpi serialization REQUIRED) INCLUDE_DIRECTORIES(${Boost_INCLUDE_DIRS}) TARGET_LINK_LIBRARIES(test ${Boost_LIBRARIES}) </code></pre> <p>It cannot find boost_mpi:</p> <pre><code>CMake Error at /usr/share/cmake/Modules/FindBoost.cmake:1135 (message): Unable to find the requested Boost libraries. Boost version: 1.47.0 Boost include path: /usr/include The following Boost libraries could not be found: boost_mpi </code></pre> <p>But! I have installed next packages:</p> <pre><code>boost-graph-mpich2 boost-mpich2 boost-mpich2-devel boost-mpich2-python mpich2 mpich2-devel </code></pre> <p>Why it can't find? There are a plenty examples over Internet where people use <strong>FIND_PACKAGE(Boost 1.4 COMPONENTS mpi REQUIRED)</strong>.</p>
