[opensuse-arm] Experiences with Build325.4 for RPi1
Earlier a second boot of a system generated with this build for Raspberry Pi 1B did not work. Now I have a system that works and can be booted again. However trying to start a module with yast (ncurses), I tried network, software repositories and software all end in the following error message: /sbin/yast: line 426: 19947 Segmentation fault $ybindir/y2base $module "$@" "$SELECTED_GUI" $Y2_GEOMETRY $Y2UI_ARGS However 19947 in the above message differs with the type of module called and with the locale used. The repository still does not contain the ruby 2.2 modules for libstorage. I build these modules, which went OK. I noticed gcc5 was used. I will continue with this build to configure the applications I use. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Do you think you could gdb the y2base binary to figure out where exactly it segfaults? Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Alex, I have no experience with gdb. I know it is used to debug and one can set breakpoints and step through the code, but that's all I know. I tried to run yast in one console and did "gdb -p process-id" in another after installing yast2-core-debugger. However it likes to have yast2-core- debuginfo which is not available. After giving a c in gdb and selecting software in the ncurses console, gdb continues with the following output: (gdb) c Continuing. Detaching after fork from child process 20159. [Thread 0xb601f450 (LWP 20077) exited] [Thread 0xb631b450 (LWP 20076) exited] [Inferior 1 (process 20075) exited normally] (gdb) quit On the ncurses console it gets back to the original yast screen and after <Alt>Q I see the error message. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

No worries, there's always a first time :). In this case, all we need is to attach to the program and then do 'bt' when we see the segfault.

This means that the process was doing just fine, no segfault. So maybe a different PID was the one broken? Which PID did you attach to? According to the log, "y2base" is the application that faults. If you can't find it, try to attach strace -f to the yast binary to figure out which binary gets executed. The strace should also at least print out which PID segfaulted.

I did attach to the y2base process. I think the segfault is in the forked process shown above as 20159, which is not present when I start gdb. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

I started yast in one console and selected Software Management in the right sub window without pressing Return. In a second console I gave the command: ps aux to find the pid of the y2base process after that I gave the command: strace -ff -p 25721 >strace.1 2>strace.2 I pressed Return in the first console and after reappearing of the main ncurses window of yast I entered <Alt>Q, which also ended strace. I found only strace.2 having output. I will send that in a separate private message. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
