Shivku, Some info may get sent to /var/log/messages when a segfault occures. You can run 'tail -f /var/log/messages' in one terminal window and run wvdialconf in another one and see what is appended to the messages file. Also, run dmesg before and after the crash occures. IIRC a core file is created when an application crashes. Basically, it is a memory snapshot of the state of the process when it crashed. I think that modern kernels by default are configured not to dump the core file (I haven't seen one for the last 9 years or so). It is useless for regular users, so the feature has been turned off at some point. Do you get any warnings reported during the compilation? There is also a newer package, the 8th revision available somewhere at the Zsolt's site. Search the list archive for this message: <<<< Date: Wed, 3 Jun 2009 22:29:34 +0200 From: Zsolt László BÉRCZES <zsolt@xxxxxx> To: Discuss@xxxxxxxxxxxxx Subject: new packages (was: agrsm on 2.6.30) >>>> -- WBR, Nikolay Zhuravlev Thus spake Shiva Kumar (shivku@xxxxxxxxx): > Hi, > I am not able to catch the core dump either.
