I have installed firebird 1.5 database on linux system.
Firebird installed in /usr/local/firebird.
I try to configure php with command:
configure --with-interbase=/usr/local/firebird
but configure says:
.... skipped configure output ....
checking for InterBase support... yes
checking for isc_detach_database in -lgds... no
checking for isc_detach_database in -lib_util... no
configure: error: libgds or libib_util not found! Check config.log for
more information.

Can you help me ?
