I get a compile warning when building zaptel (current CVS head) against 2.4.18 kernel (Debian stable dist) zaptel.c: In function `zt_net_close': zaptel.c:1238: warning: implicit declaration of function `hdlc_close' It completes but fails to install with modprobe finding unresolved references. This error was introduced with the introduction of the second clause of the statement below in zconfig.h #if defined(CONFIG_HDLC) || defined(CONFIG_HDLC_MODULE) ========================^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Clearly there is a problem building against the kernel modules in 2.14.18 as hdlc_close does not exist. There is no problem if I comment out the second part from and including the || above. It builds ok against 2.4.23 but I need to keep 2.4.18 for cnxadsl compatibility.
