Some users of my plptools package (http://plptools.sourceforge.net) complain that this is not compilable under RH 7.0. It uses GNU readline which in turn usually needs libtermcap for some termcap stuff. On RH7.0, libtermcap.so doesn4t export any symbols ?! (Try a nm and you4ll see yourself.) Resulting from that, libreadline doesn4t depend on libtermcap and therefore linkage fails. On my older RH system, nm libtermcap exports among others the symbols BC, PC and UP which are needed by libreadline and also a ldd libreadline.so shows correct depencies. On RH7.0 ldd libreadline.so only lists libc and ld-linux. Thanks -Fritz
In current release (libtermcap-2.0.8, FEDORA CORE) libtermcap defines and exports BC, PC and UP. It does not set a value of these 'globals'.
