| 5 | <para>Please read the following paragraphs carefully. Throughout this book the
|
|---|
| 6 | variable LFS will be used frequently. $LFS must at all times be replaced with
|
|---|
| 7 | the directory where the partition that contains the LFS system is mounted. How
|
|---|
| 8 | to create and where to mount the partition will be explained in full detail in
|
|---|
| 9 | Chapter 3. For the moment let's assume that the LFS partition is mounted on
|
|---|
| 10 | <filename>/mnt/lfs</filename>.</para>
|
|---|
| 11 |
|
|---|
| 12 | <para>When you are told to run a command like
|
|---|
| 13 | <userinput>./configure --prefix=$LFS/tools</userinput>, you actually have to
|
|---|
| 14 | execute <userinput>./configure --prefix=/mnt/lfs/tools</userinput>.</para>
|
|---|
| 15 |
|
|---|
| 16 | <para>It's important that this is done no matter where it is read; be it in
|
|---|
| 17 | commands entered in a shell, or in a file edited or created.</para>
|
|---|
| 18 |
|
|---|
| 19 | <para>A possible solution is to set the environment variable LFS.
|
|---|
| 20 | This way $LFS can be entered literally instead of replacing it with
|
|---|
| 21 | /mnt/lfs. This is accomplished by running: </para>
|
|---|
| 22 |
|
|---|
| 23 | <para><screen><userinput>export LFS=/mnt/lfs</userinput></screen></para>
|
|---|
| 24 |
|
|---|
| 25 | <para>Now, if you are told to run a command such as
|
|---|
| 26 | <userinput>./configure --prefix=$LFS/tools</userinput>, then you may type it
|
|---|
| 27 | literally. Your shell will replace "$LFS" with "/mnt/lfs" when it processes
|
|---|
| 28 | the command line (that is, when you hit Enter after having typed the
|
|---|
| 29 | command).</para>
