Hi: When I compile parallel boost graph library, I encounter the following errors:

parallel-bgl-0.7.0/boost/graph/distributed/adjlist/serialization.hpp: In function `std::vector boost::detail::parallel::available_process_files(const std::string&)': parallel-bgl-0.7.0/boost/graph/distributed/adjlist/serialization.hpp:97: error: conversion from `boost::filesystem3::path' to non-scalar type `std::basic_string' requested 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

The CMake found the following software:  gcc (GCC) 3.4.6, Boost version: 1.46.0 and openmpi 1.3, c++ (GCC) 3.4.6 20060404 (Red Hat 3.4.6-11)

Do you guys have an idea what the problem is?

There is a more updated version of PBGL in the Boost repository (see boost/graph/distributed and libs/graph_parallel); that does not have the problem you experienced. -- Jeremiah Willcock
