11 | <title>Setting The ${CLFS} Variable</title> |
---|
12 | |
---|
13 | <para>Throughout this book, the environment variable <envar>CLFS</envar> will |
---|
14 | be used several times. You should ensure that this variable is always defined |
---|
15 | throughout the CLFS build process. It should be set to the name of the |
---|
16 | directory where you will be building your CLFS system - we will use |
---|
17 | <filename class="directory">/mnt/clfs</filename> as an example, but the |
---|
18 | directory choice is up to you. If you are building CLFS on a separate |
---|
19 | partition, this directory will be the mount point for the partition. |
---|
20 | Choose a directory location and set the variable with the |
---|
21 | following command:</para> |
---|
22 | |
---|
23 | <screen><userinput>export CLFS=<replaceable>[/mnt/clfs]</replaceable></userinput></screen> |
---|
24 | |
---|
25 | <para>Having this variable set is beneficial in that commands such as |
---|
26 | <command>install -dv ${CLFS}/tools</command> can be typed literally. The shell |
---|
27 | will automatically replace <quote>${CLFS}</quote> with |
---|
28 | <quote>/mnt/clfs</quote> (or whatever the variable was set to) when it |
---|
29 | processes the command line.</para> |
---|
30 | |
---|
31 | <para>Do not forget to check that <envar>${CLFS}</envar> is set whenever |
---|
32 | you leave and reenter the current working environment (such as when doing a |
---|
33 | <command>su</command> to <systemitem class="username">root</systemitem> or |
---|
34 | another user). Check that the <envar>CLFS</envar> variable is set up |
---|
35 | properly with:</para> |
---|
36 | |
---|
37 | <screen><userinput>echo ${CLFS}</userinput></screen> |
---|
38 | |
---|
39 | <para>Make sure the output shows the path to your CLFS system's build |
---|
40 | location, which is <filename class="directory">/mnt/clfs</filename> if the |
---|
41 | provided example was followed. If the output is incorrect, use the command |
---|
42 | given earlier on this page to set <envar>${CLFS}</envar> to the correct |
---|
43 | directory name.</para> |
