Pb with compilation

[Lam <lam_ worldonline fr>]

I have a problem with my program
I try to compile it, but now i can't (i compil it yet before !)
but now i have an error with the flags "-ldb" :

$> gnome-config --libs gnome
-L/usr/lib -lgnome -lgnomesupport -lesd -laudiofile -lm -ldb -lglib -ldl

$> gnome-config --libs gnomeui
-rdynamic -L/usr/lib -L/usr/X11R6/lib -lgnomeui -lart_lgpl -lgdk_imlib -lSM -lICE -lgtk -lgdk -lgmodule -lXi -lXext -lX11 -lgnome -lgnomesupport -lesd -laudiofile -lm -ldb -lglib -ldl

I have this error when i do make

/usr/bin/ld: cannot find -ldb
collect2: ld returned 1 exit status
make: *** [gipag] Error 1

could u help me ? what is "-ldb" ?
how i can repear ?
