[cmake-developers] Random hang of building process: deedlock in cmake.

Alexander, Yes - you are right. It's just excellent illustration why I hate pipes. So CMake guys can remove this crap from their code and use socketpair() or like instead. \\wbr On Fri, Jul 11, 2014 at 12:33 PM, Kanevskiy, Alexander alexander.kanevs...@intel.com wrote: On 11/07/14 12:15 , Vitaly Chernooky vitalii.chernoo...@globallogic.com wrote: This looks like old “good” bug in qemu that sometimes re-appear in certain combination of host environment and sources you’re building: https://bugs.launchpad.net/qemu/+bug/955379 Hi all!

Also it will be good if every body from us will vote for that bug on launchpad.

Re: [cmake-developers] [Dev] Random hang of building process: deedlock in cmake.
Ilya, do you still interested in build logs? I've collected them. \\wbr On Fri, Jul 11, 2014 at 12:29 PM, Ilya Palachev i.palac...@samsung.com wrote: Hi, Vitaly. Maybe your backtrace information will be somehow more useful if you download and unrpm debuginfo and debugsource rpm packages from the repository that you use as default repository in your ~/.gbs.conf If you use native gdb (not in chroot) these RPMs should be unrpm'ed inside root (/) directory, so that new files will appear in directories /usr/lib/debug and /usr/src/debug. I have already noticed cmake's hanging in our build system for many times about 2 yours ago. Maybe it's specific for our environment. Also the output log of cmake will be useful. Does cmake hangs during the search of some libraries?
