2 # Makefile.dist for libdhcp4client
4 # We get the libdhcp4client library from the patched ISC source code. We
5 # rebuild key C files with -DLIBDHCP to turn on the library features we
6 # need. Normal build results in standard ISC code (i.e., not LIBDHCP
7 # stuff enabled). We then link together a static library and a shared
8 # library with the new resulting objects.

109 # We need to use client/dhclient.c, so we make this link:
110 # rm -f client_dhclient.c
111 # ln -s $(TOP)/client/dhclient.c client_dhclient.c
113 # Simple. Given the way the ISC build system works, this is the easiest to
114 # maintain and least invasive.
