 +Remember, as I stated earlier, we want to build everything as static binaries. ​ This usually requires that we make some changes to the build process or invoke special switches for the config process.\\
 +\\
 +(Note : Due to compilation errors, you must download "​dhcp-4.1.1b1.tar.gz"​ or above. ​ As you will see, I started experiencing problems that are beyond my abilities. ​ Switching to "​dhcp-4.1.1b1"​ seems to have solved those problems for now.)\\
 +\\
 +Extract your dhcp source archive in your /scratch directory. From /scratch execute "tar xvzf /​scratch/​dhcp-xxxxx.tar.gz" ​ This assumes you have placed the archive in /​scratch. ​ If not, simply point to the correct location and extract the archive while in /scratch.\\
 +\\
 +In the case of DHCP, we have to execute the following switches during the configure process.\\
 +\\
 +Change to your DHCP src directory. In my case. "cd /​scratch/​dhcp-4.1.0/"​\\
 +\\
 +Then execute the following command..\\
 +CFLAGS="​-static"​ ./​configure\\
 +\\
 +Once the configure process is complete, and provided there were no errors.\\
 +Execute the following commands.\\
 +\\
 +make clean\\
 +\\
 +Then\\
 +\\
 +make\\
 +\\
 +I experienced <​del>​[[elf-ebi-initramfs-lnxi-howto/​packages/​dhcp_-_build_instructions/​errors]]</​del>​ during the build process. ​ Click the word errors to learn what my work around(s) was/were.\\
 +( As stated above, in the end, the work around was to advance to a higher version of dhcp )\\
 +\\
 +Again, provided there were no errors during the build process you should be left with a file in /​scratch/​dhcp-4.1.1b1/​client named "​dhclient"​.\\
 +\\
 +Verify that it was built statically by executing the following command.\\
 +file /​scratch/​dhcp-4.1.1b1/​bash ( Fully path it to make sure it doesn'​t pick up on anything else. )\\
 +
 +Your output should look like this.\\
 +[root@demo dhcp-4.1.1b1]#​ file /​scratch/​dhcp-4.1.1b1/​client/​dhclient \\
 +/​scratch/​dhcp-4.1.1b1/​client/​dhclient:​ ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, statically linked, not stripped\\
 +\\
 +If it looks like the example below, you must figure out what has gone wrong. ​ It is more trouble than it's worth. ( IMH0 ) To build a bunch of dynamically linked packages that you have to find all the libs for.\\
 +\\
 +/​scratch/​dhcp-4.1.1b1/​client/​dhclient:​ ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), not stripped <-- THIS IS BAD!\\
