<title>About $LFS</title>
|
|
<?dbhtml filename="aboutlfs.html" dir="chapter02"?>
|
|
|
|
<para>Please read the following paragraphs carefully. Throughout this book the
|
|
variable LFS will be used frequently. $LFS must at all times be replaced with
|
|
the directory where the partition that contains the LFS system is mounted. How
|
|
to create and where to mount the partition will be explained in full detail in
|
|
Chapter 4. For the moment let's assume that the LFS partition is mounted on
|
|
<filename>/mnt/lfs</filename>.</para>
|
|
|
|
<para>When you are told to run a command like
|
|
<userinput>./configure --prefix=$LFS/tools</userinput>, you actually have to
|
|
execute <userinput>./configure --prefix=/mnt/lfs/tools</userinput>.</para>
|
|
|
|
<para>It's important that this is done no matter where it is read; be it in
|
|
commands entered in a shell, or in a file edited or created.</para>
|
|
|
|
<para>A possible solution is to set the environment variable LFS.
|
|
This way $LFS can be entered literally instead of replacing it with
|
|
/mnt/lfs. This is accomplished by running: </para>
|
|
|
|
<para><screen><userinput>export LFS=/mnt/lfs</userinput></screen></para>
|
|
|
|
<para>Now, if you are told to run a command such as
|
|
<userinput>./configure --prefix=$LFS/tools</userinput>, then you may type it
|
|
literally. Your shell will replace "$LFS" with "/mnt/lfs" when it processes
|
|
the command line (that is, when you hit Enter after having typed the
|
|
command).</para>
