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

I did a gnu/openmpi 1.8.2 build on ubuntu which exhibit the same problem. Can the fact that the setgpid system calls fails be an issue ? I notice they are among the few sys call those return code is not tested (under gdb, I noticed they return 13 (PERM issue)). Alain On 21/10/2014 15:56, Belcourt, Kenneth wrote:

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.
