Re: [Boost-users] [parallel graph] error building parallel BGL
Hi Jeremiah, I can confirm that ParallelBGL that comes with 1.53 compiles. The problem with this one is that when I try to compile the example (again from 1.53) I get this problem: /usr/local/include/boost/graph/distributed/mpi_process_group.hpp:419:28: No viable conversion from 'shared_ptrboost::graph::distributed::mpi_process_group::impl' to 'bool' 1) Any ideas? 2) Any location that I can find more examples of the Parallel BGL? Best, Tasos

Where is the example that you are trying from? The ones in the Boost tree all pass for me. If you write a simple test that just makes a Boost shared_ptr<int> and tries to convert it to a bool, does that work (even an implicit conversion should work, I think). -- Jeremiah Willcock

I think shared_ptr was recently changed to use explicit operator bool in C++11. In Christ, Steven Watanabe

I think shared_ptr was recently changed to use
explicit operator bool
in C++11.
That's the kind of thing I suspect is occurring; I know that the trunk versions of some Boost components that use shared_ptr were broken for a while. -- Jeremiah Willcock
