[47fcdfd] | 11 | <title>Setting The ${CLFS} Variable</title> |
---|
[3f8be484] | 12 | |
---|
[9988ef0] | 13 | <para>Throughout this book, the environment variable <envar>CLFS</envar> will |
---|
[57413c8] | 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> |
---|
[3f8be484] | 22 | |
---|
[3d92c8d] | 23 | <screen><userinput>export CLFS=<replaceable>/mnt/clfs</replaceable></userinput></screen> |
---|
[3f8be484] | 24 | |
---|
| 25 | <para>Having this variable set is beneficial in that commands such as |
---|
[040521bc] | 26 | <command>install -dv ${CLFS}/tools</command> can be typed literally. The shell |
---|
| 27 | will automatically replace <quote>${CLFS}</quote> with |
---|
[9988ef0] | 28 | <quote>/mnt/clfs</quote> (or whatever the variable was set to) when it |
---|
[3f8be484] | 29 | processes the command line.</para> |
---|
| 30 | |
---|
[040521bc] | 31 | <para>Do not forget to check that <envar>${CLFS}</envar> is set whenever |
---|
[57413c8] | 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 |
---|
[c07fa0e] | 34 | another user). Check that the <envar>CLFS</envar> variable is set up |
---|
| 35 | properly with:</para> |
---|
| 36 | |
---|
| 37 | <screen><userinput>echo ${CLFS}</userinput></screen> |
---|
| 38 | |
---|
[57413c8] | 39 | <para>Make sure the output shows the path to your CLFS system's build |
---|
| 40 | location, which is <filename class="directory">/mnt/clfs</filename> if the |
---|
[c07fa0e] | 41 | provided example was followed. If the output is incorrect, use the command |
---|
[57413c8] | 42 | given earlier on this page to set <envar>${CLFS}</envar> to the correct |
---|
[c07fa0e] | 43 | directory name.</para> |
