you should use the gda-config script (which works exactly as
glib-config, gtk-config, gnome-config...). So, when compiling:
gcc -o file.o `gda-config --cflags client-ui` -c file.c
gcc -o file `gda-config --libs client-ui` file.o
I'm not sure if the 0.0.96 supports 'client-ui`, so if not, use gdaui
instead. Anyway, if you run gda-config with no parameters, it will show
a help screen with all the available libraries.

no, it's not. First of all, you must create the Gda_Connection object,
which it does not appear to be created in this code. So,
Gda_Connection* connection = gda_connection_new(gnome_CORBA_ORB());
gda_connection_open(connection, "DSN=dbname;HOST=localhost", user,
But, as I see you're making your own dialog for connecting, why don't
you use the GnomeDbLoginDialog widget? it is there for helping you!! You
can see how to use it in gASQL,
in gda-fe/, in gda-rolodex/ and in the testing/glade/db_login directory.
And as I also see that you're using libglade, you may want to put the
GnomeDb-specific widgets directly in your form designed in Glade. This
is supported in the CVS version of Glade. They are not very advanced,
you can only put them in the resulting .glade file, so you may also want
to hack on this code to make them useful when using them from glade.
