I have very occasionally hit hung tasks, but I was usually able to identify the exact task which was hanging, it was never "many". Note that some tasks which may appear "hung" may be waiting for a dependency to complete. You could try some brute force debugging...set these in local.conf:
BB_NUMBER_THREADS = "1" PARALLEL_MAKE = "-j1" Then try building again, and yes it will take a long time. if something is actually hanging, it would be useful to know what task, not only the bitbake "task" but the actual process as reported by ps. A bitbake "task" can spawn many processes as it works to complete it's job. In the past, once I found the hanging process, strace usually helped me discover why. You mention a "low-end" 2-core machine...RAM is everything. If you're running Linux out of memory, you get what you deserve <grin> Remember, poky-tiny refers to the resulting distribution you are building, not the machine you want to build it on ;) -Chris On Mon, Apr 11, 2016 at 9:38 PM, Ronald Oakes <rona...@brc2.com> wrote: > It looks like it is hanging fairly consistently during the > gcc-cross-initial-x86_64-5.2.0-r0 do_compile or do_install steps. > I've tried stopping, cleaning, and just building > gcc-cross-initial-x86_64, but it still hangs. > > I'm going to try a 32 bit build just to see if I can get past this. > > Ron Oakes > > On Mon, Apr 11, 2016 at 12:35 PM, Andre McCurdy <armccu...@gmail.com> > wrote: > > On Mon, Apr 11, 2016 at 11:22 AM, Ronald Oakes <rona...@brc2.com> wrote: > >> Over the weekend, I upgraded my connected development platform to > >> Debian 8.4.0 from Centos 7. > >> > >> However, today I have yet to make a successful poky-tiny build for > >> either coreI7-64 or qemux86-64.
