Hi, Srinidhi has asked about GDB on IRC, and I had to look this up, so here it is before I forget. This applies to SLE12 code base (and openSUSE Leap 42.x). In new code (since 2017-04) we have started embedding YaST in Ruby so the startup sequence is different. The problems are two: starting GDB, and setting a breakpoint. I. Starting GDB Starting the installation with simply "Y2GDB=1" does not work anymore :-/ apparently gdb does not get installed. To work around this, I-1. Boot with
y2gdb=1 startshell=1
I-2. At the shell prompt $ extend gdb $ exit # to proceed with the installation I-3. A black screen with the mouse cursor comes up. You need to switch to the 1st console with Ctrl-Alt-F1. II. Setting a breakpoint It is not so simple, because the code is not yet there when you enter main(); it is dlopen'd later on. II-1. On the gdb prompt, let it load the plugins: (gdb) b main (gdb) r (gdb) b Y2RubyClientComponent::doActualWork II-2. Now all libraries are loaded. Set your actual breakpoint and happy debugging. (Well, the debuginfos are missing. I would use the DUD=foo.rpm boot parameter to get them in.) -- Martin Vidner, YaST Team http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu
