| dhcpcd-4 - DHCP client daemon |

| 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 an MMU-less system where fork() does not work, you |
| should add -DTHERE_IS_NO_FORK to your CPPFLAGS. |
| This also puts the --no-background flag on and stops the --background flag |
| from working. |
| |
| 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 dhcpcd-hooks are installed by default. |
| By default we install 01-test, 10-mtu, 20-resolv.conf and 30-hostname. |
| To add more simply add them in the HOOKSCRIPTS variable. |
| make HOOKSCRIPTS=50-ntp install |
| |
| |
| Compatibility |
| ------------- |
| If you require compatibility with dhcpcd-3 and older style variables, |
| you can install 50-dhcpcd-compat into the directory $LIBEXECDIR/dhcpcd-hooks |
| We don't install this by default. |
| You should also add -DCMDLINE_COMPAT to your CPPFLAGS 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. |
