Slackware 14.1 x64 -- Issues with GDB 7.x
When launching gdb on an application I am greeted with the following error:
&"warning: GDB: Failed to set controlling terminal: Inappropriate ioctl for device\n"
Could not load shared library symbols for linux-gate.so.1.
Do you need "set solib-search-path" or "set sysroot"?
Some googling of this provided a whole myriad of garbage, from patches to finger pointing, and other sorts of hand waiving.
Frequently people say that this is a harmless warning and can be ignored. I am thinking that is not the case.
I am debugging a 32bit application. SlackVer is x64.
GDB gets the shared kernel object : linux-vdso.so.1 which resides at 0x00007fffc7dde000
my application gets: linux-gate.so.1 which resides at 0xffffe000
At any rate, gdb is not working right at all. I can set break points, step through, step over etc. That's all fine an dandy, however it fails to give me values if I add an expression evaluation. I can set a break point before a variable is set, at it, then immediately after. GDB stops at all the points but does not have a value for me.
This makes debugging next to impossible with gdb.
If anyone had this issue and has since resolved it your input would be greatly appreciated.
[Edit]: For what its worth I am debugging a multi thread program which is interfacing with other applications.
