Internet Systems Consortium (ISC) DHCP offers both an IPv4 and IPv6 DHCP (Dynamic Host Configuration Protocol) Client and Server.
The DHCP source includes a copy of ISC Bind and will build the BIND Export Libraries required for DHCP. Cross Compiling the BIND libraries are problematic for two reasons. First, the host and target parameters are not passed to Bind's Configure. Secondly, once BIND has been configured for cross compiling, there is an executable (gen) that is cross-compiled, but executed on the build machine.
To overcome these two issues, two patch files have been created.
To build ISC DHCP, download the source and the patches:
wget ftp://ftp.isc.org/isc/dhcp/4.3.0b1/dhcp-4.3.0b1.tar.gz wget http://wiki.beyondlogic.org/patches/dhcp-4.3.0b1.bind_arm-linux-gnueabi.patch wget http://wiki.beyondlogic.org/patches/bind-9.9.5rc1.gen_crosscompile.patch tar -xzf dhcp-4.3.0b1.tar.gz
Now we patch the makefile that is responsible for building BIND. The patch adds the --host=arm-linux-gnueabi --target=arm-linux-gnueabi --build=i686-pc-linux-gnu parameters to configure, and specifically tells it to use /dev/random:
cd dhcp-4.3.0b1 patch -p1 < ../dhcp-4.3.0b1.bind_arm-linux-gnueabi.patch
Next we need to correct the makefile responsible for compiling gen.c. As the BIND source has not yet been uncompressed, we must first extract it prior to patching:
tar -xzf bind.tar.gz cd bind-9.9.5rc1 patch -p1 < patch -p1 < ../../../bind-9.9.5rc1.gen_crosscompile.patch cd ../..
Now we should be all set to configure and cross-compile DHCP:
./configure --host=arm-linux-gnueabi --prefix= --build=i686-pc-linux-gnu ac_cv_file__dev_random=yes make make install DESTDIR=/home/export/rootfs
During install, some sample configuration files should be placed in /etc.
If running DHCPd, it may complain it is unable to open the leases database:
Can't open lease database /var/db/dhcpd.leases: No such file or directory -- check for failed database rewrite attempt!
If so, create a blank lease file:
touch /var/db/dhcpd.leases
Once your configuration file is ready to go, you can start an IPv4 DHCP server by:
