| [b822811] | 5 | <para>Please read the following carefully: throughout this book
|
|---|
| [2c094d6] | 6 | the variable LFS will be used frequently. $LFS must at all times be
|
|---|
| [fada431] | 7 | replaced with the directory where the partition that contains the LFS system
|
|---|
| [6370fa6] | 8 | is mounted. How to create and where to mount the partition will be
|
|---|
| [26e62aa] | 9 | explained in full detail in Chapter 4. For example, let's assume that
|
|---|
| [fada431] | 10 | the LFS partition is mounted on /mnt/lfs.</para>
|

| [97f1db3] | 11 |
|

| [1e6acd6] | 12 | <para>When you are told to run a command like
|
|---|
| [60ed866] | 13 | <userinput>./configure --prefix=$LFS/static</userinput> you actually have to
|
|---|
| 14 | execute <userinput>./configure --prefix=/mnt/lfs/static</userinput>.</para>
|
|---|
| [6370fa6] | 15 |
|
|---|
| [b822811] | 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>
|
|---|
| [6370fa6] | 18 |
|
|---|
| [b822811] | 19 | <para>A possible solution is to set the environment variable LFS.
|
|---|
| [fada431] | 20 | This way $LFS can be entered literally instead of replacing it with
|
|---|
| [6ad9627] | 21 | /mnt/lfs. This is accomplished by running: </para>
|
|---|
| 22 |
|
|---|
| 23 | <para><screen><userinput>export LFS=/mnt/lfs</userinput></screen></para>
|
|---|
| [6370fa6] | 24 |
|
|---|
| [2294abc] | 25 | <para>Now, if you are told to run a command such as
|
|---|
| 26 | <userinput>./configure --prefix=$LFS/static</userinput>, then you may type
|
|---|
| 27 | it literally. Your shell will replace $LFS with /mnt/lfs when it processes
|
|---|
| 28 | the command line (meaning when you hit enter after having typed the
|
|---|
| 29 | command).</para>
