How to use -dbg packages (and specifically libncurses5-dbg) ?
Hello,
I'm trying to debug an own C program which dumps a core, inside libncurses5 library.
I'd like to use gdb to debug my program, and so I've installed -dbg packages :
libc6-dbg, libncurses5-dbg, libstdc++-6.4.3-dbg (on a Debian Lenny system), but if the libc6's
debug package is used by gdb, the libncurses5-dbg seems to be skipped :
> > gdb ecran core.ecran
>
GNU gdb 6.8-debian

Does I have to redo the compilation before to test my program with libncurses5-dbg debug library ?
Or is there something I forgot ?
thanks for any help,
Fred.
