RE: What do I need to look at the source while debugging?

["Fahd Abidi" <fabidi at ultsol dot com>]

First make sure that your program file (SQLDriverConnectW.o) is build
with debug symbols. to accomplish this make sure you pass the "-g" flag
into gdb. Then open gdb with the following arguments:

linux# gdb SQLDriverConnectW.o
You will need to attach this gdb session to a gdbserver to begin the
debugging. So start your application with the following commands:

linux# gdbserver SQLDriverConnectW.o

I forget the exact command to give to gdbserver to specify what port you
will use to connect. Next from gdb connect to the gdbserver:

(gdb) target remote ****your connection settings****

Hi,
I just tried to use a 'load' command:

(gdb) load
/home/igor/portage/dev-db/unixODBC-2.2.12/work/unixODBC-2.2.12/DriverMan
ager/SQLDriverConnectW.c
`system-supplied DSO at 0xffffe000' has disappeared; keeping its
symbols.
You can't do that when your target is `multi-thread'

What does this mean? I just used KDdevelop to create a project...

and simply trying:

(gdb) break
/home/igor/portage/dev-db/unixODBC-2.2.12/work/unixODBC-2.2.12/DriverMan
ager/SQLDriverConnect.c:616
No source file named
/home/igor/portage/dev-db/unixODBC-2.2.12/work/unixODBC-2.2.12/DriverMan
ager/SQLDriverConnect.c.
Make breakpoint pending on future shared library load? (y or [n]) y

Breakpoint 2
(/home/igor/portage/dev-db/unixODBC-2.2.12/work/unixODBC-2.2.12/DriverMa
nager/SQLDriverConnect.c:616) pending.

However the file exists and I have a reading permission...

Thank you.
