dhcpcd-4 - DHCP client daemon
Copyright 2006-2008 Roy Marples <roy@marples.name>
Installation
------------
Edit config.h to match your building requirements.
Then just make; make install
man dhcpcd for command line options
Notes
-----
If you're cross compiling you may need to set the below knobs to avoid
automatic tests.
OS=BSD | Linux
If you're building for a NOMMU system where fork() does not work, you should
add -DTHERE_IS_NO_FORK to your CFLAGS.
You can change the default dir with these knobs.
For example, to satisfy FHS compliance you would do this:-
LIBEXECDIR=/lib/dhcpcd
DBDIR=/var/lib/dhcpcd
We now default to using -std=c99. For 64-bit linux, this always works, but
for 32-bit linux it requires either gnu99 or a patch to asm/types.h.
Most distros patch linux headers so this should work fine.
linux-2.6.24 finally ships with a working 32-bit header.
If your linux headers are older, or your distro hasn't patched them you can
set CSTD=gnu99 to work around this.
Hooks
-----
Not all the hooks in hook.d are installed by default.
By default we install 01-test.sh, 10-resolv.conf.sh and 15-hostname.sh.
To add more simply add them in the HOOKSCRIPTS variable.
make HOOKSCRIPTS=50-ntp.sh install
Compatibility
-------------
If you require compatibility with dhcpcd-3 and older style variables,
you can install 50-dhcpcd-compat.sh into the directory $LIBEXECDIR/dhcpcd.hook.d
We don't install this by default.
You should also add -DCMDLINE_COMPAT to your CFLAGS if you need to be fully
commandline compatible with prior versions.
dhcpcd-3 enabled DUID support by default - this has changed in dhcpcd-4.
You can enable it via the --duid, -D command line option or by using the
duid directive in dhcpcd.conf.
If CMDLINE_COMPAT is defined the we renable DUID support by default IF
the dhcpcd.duid file exits. This keeps the clients working as they were,
which is good.
dhcpcd-4 is NOT fully commandline compatible with dhcpcd-2 and older and
changes the meaning of some options.
