Hi all, My boost.mpi test seems ok: ####################### ➜ Temp mpic++ -I/usr/local/include/boost/mpi/ mpitest2.cc - L/usr/local/lib/ -lboost_mpi-mt -lboost_serialization-mt ➜ Temp ./a.out I am process 0 of 1. ➜ Temp mpirun -n 6 ./a.out I am process 1 of 6. I am process 4 of 6. I am process 0 of 6. I am process 3 of 6. I am process 5 of 6. I am process 2 of 6. ###################### But when I try to build parallelBGL I get the following error: ###################### ➜ parallelBGL-Mac cmake ../parallelBGL/ -- The C compiler identification is Clang 4.2.0 -- The CXX compiler identification is Clang 4.2.0 -- Check for working C compiler: /usr/bin/cc -- Check for working C compiler: /usr/bin/cc -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Boost version: 1.53.0 -- Found the following Boost libraries: -- mpi -- serialization -- filesystem -- system -- thread -- Configuring done -- Generating done -- Build files have been written to: /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL-Mac ➜ parallelBGL-Mac make Scanning dependencies of target boost_graph_mpi [ 2%] Building CXX object libs/graph_parallel/src/CMakeFiles/boost_graph_mpi.dir/mpi_process_group.cpp.o Linking CXX static library ../../../lib/libboost_graph_mpi.a [ 5%] Built target boost_graph_mpi Scanning dependencies of target adjlist_build_test [ 8%] Building CXX object libs/graph_parallel/test/CMakeFiles/adjlist_build_test.dir/adjlist_build_test.cpp.o In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/libs/graph_parallel/test/adjlist_build_test.cpp:10: In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjacency_list.hpp:51: /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/named_graph.hpp:345:12: warning: reference 'self' is not yet bound to a value when used here [-Wuninitialized] : self(self), name(other.name), committed(other.committed) ^ In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/libs/graph_parallel/test/adjlist_build_test.cpp:10: In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjacency_list.hpp:3961: /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:97:27: error: no viable conversion from 'boost::filesystem::path' to 'std::string' (aka 'basic_string<char>') std::string process_name = i->path().filename(); ^ ~~~~~~~~~~~~~~~~~~~~ /usr/include/c++/4.2.1/bits/basic_string.h:434:7: note: candidate constructor not viable: no known conversion from 'boost::filesystem::path' to 'const std::basic_string<char> &' for 1st argument basic_string(const basic_string& __str); ^ /usr/include/c++/4.2.1/bits/basic_string.h:469:7: note: candidate constructor not viable: no known conversion from 'boost::filesystem::path' to 'const char *' for 1st argument basic_string(const _CharT* __s, const _Alloc& __a = _Alloc()); ^ In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/libs/graph_parallel/test/adjlist_build_test.cpp:10: In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjacency_list.hpp:3961: /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:841:37: error: no type named 'retag_property_list' in namespace 'boost::detail' typedef typename boost::detail::retag_property_list< ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:841:56: error: expected unqualified-id typedef typename boost::detail::retag_property_list< ^ /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:876:25: error: unknown type name 'edge_property_type'; did you mean 'edge_property_tag'? , static_cast(get(edge_all_t(), g, e)) ^~~~~~~~~~~~~~~~~~ edge_property_tag /usr/local/include/boost/graph/properties.hpp:69:10: note: 'edge_property_tag' declared here struct edge_property_tag { }; ^ In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/libs/graph_parallel/test/adjlist_build_test.cpp:10: In file included from /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjacency_list.hpp:3961: /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:955:37: error: no type named 'retag_property_list' in namespace 'boost::detail' typedef typename boost::detail::retag_property_list< ~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~ /Users/varoudis/Dropbox/Projects/Libraries/parallelBGL/boost/graph/distributed/adjlist/serialization.hpp:955:56: error: expected unqualified-id typedef typename boost::detail::retag_property_list< ^ 1 warning and 6 errors generated. make[2]: *** [libs/graph_parallel/test/CMakeFiles/adjlist_build_test.dir/adjlist_build_test.cpp.o] Error 1 make[1]: *** [libs/graph_parallel/test/CMakeFiles/adjlist_build_test.dir/all] Error 2 make: *** [all] Error 2 ########################## Best, Tasos
