Re: [Boost-users] [EXTERNAL] bjam hangs on select (in develop branch)

Hi, I don't know if it can help, but I attached a minimal (ok, let say small) example that reproduces the problem without the mpi test nor boost code. It's basically a minimized ~100loc version of bjam. I sent it to intel so they can investigate, since mpiexec.hydra might be part of the problem. Although I think bjam should be able to deal with it since the mpi test passes on the command line. Alain On 21/10/2014 15:56, Belcourt, Kenneth wrote:

bottom of b2 strace:

lseek(4, 0, SEEK_CUR) = -1 ESPIPE (Illegal seek) rt_sigprocmask(SIG_BLOCK, [CHLD], NULL, 8) = 0 select(5, [4], NULL, NULL, NULL Okay, that’s helpful. Let me try a couple of other things. Thanks Alain.
