Re: Help on a gdb error

Hi,

I would suggest you to elaborate a little bit on this if you want people to give you meaningful answers.

 From what I see, that trace could come from anywhere, not necessarily ROOT related.

Could you explain what you are doing? ... as in: attaching the file producing it with the appropriate instructions that allow everybody to reproduce the error (ideally, that file should have less than 50 lines of code).

Are you using ROOT? what version? did you compile it in debug mode? are you on Linux, Windows, Mac? etc, etc... (at least put the complete backtrace).

Usually, someone will feel obliged to answer you if you have taken enough steps to provide them with an easy way to see the problem... even if it's not related to ROOT. On the other hand, people tend to ignore mails just saying that something doesn't work.

Cheers,
Leo

P.S: If you just want to know what the "??" means when you use gdb then a tutorial would be more suitable for this (I just stumbled upon http://live.gnome.org/GettingTraces/Details   ) but I doubt it's helpful to know that libc wasn't compiled with debugging symbols ...
