Description djarvie 2001-04-08 18:19:29 UTC

(*** This bug was imported into bugs.kde.org ***)

Package:           kdevelop
Version:           KDE 2.1.1 
Severity:          wishlist
Installed from:    SuSE RPMs
Compiler:          Not Specified
OS:                Linux
OS/Compiler notes: Not Specified

When the Debug -> Start menu option is selected KDevelop currently doesn't give any indication whatsoever if there is a problem running gdb. It just sits there and does and says nothing! It should output an error message saying that it failed to run gdb.

A simple message would save much time and trouble if this happens as it did to me - it would point the way directly to the cause of the non-event so that the user could investigate it.

By the look of 62832 and 72546 it is not solved yet.
