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?
Best regards,
Ilya Palachev

Hi all!
Today I caught again a hang of local building process.
I used debugger and strace in steps to catch a bug.
so:
$ pstree
...
| | ??gbs???sh???depanneur???sh???sudo???build???perl
? ? ?
??su???rpmbuild???sh???cmake???gmake
...
$ ps ax | grep gmake
...
1105 ? Z 0:00 [gmake] <defunct>
...
$ ps ax | grep cmake
...
760 ? S 0:01 /usr/bin/cmake ...
...
$ sudo strace -p 760
[sudo] password for vitalii.chernookyi:
Process 760 attached - interrupt to quit
select(4, [3], NULL, NULL, NULL^C <unfinished ...>
Process 760 detached
$ ls -l /proc/760/fd/3
lr-x------ 1 vitalii.chernookyi tizendev 64 Jul 11 11:41 /proc/760/fd/3
-> pipe:[1670438]
$ ls -l /proc/*/fd/* | grep 'pipe:\[1670438\]'
lr-x------ 1 vitalii.chernookyi tizendev 64 Jul 11 11:41 /proc/760/fd/3
-> pipe:[1670438]
l-wx------ 1 vitalii.chernookyi tizendev 64 Jul 11 11:42 /proc/760/fd/4
-> pipe:[1670438]
$ sudo gdb -p 760
...
0x0000000060138543 in ?? ()
(gdb) bt
#0 0x0000000060138543 in ?? ()
#1 0x000000006004a4ce in ?? ()
#2 0x000000006004e2fe in ?? ()
#3 0x0000000060040309 in ?? ()
#4 0x00000000600039ee in ?? ()
#5 0x00000000600d9584 in ?? ()
#6 0x0000000060003f41 in ?? ()
#7 0x00007fff61dc5e88 in ?? ()
#8 0x0000000000000000 in ?? ()
(gdb) quit
...
$
So we caught a deedlock.
Do anyone have any idea how to fix it?
