| 15 | <para os="a">During the building of the cross-compile tools you will need to
|
---|
| 16 | set a few variables that will be dependent on your particular needs.
|
---|
| 17 | The first variable will be the triplet of the host machine, which will be
|
---|
| 18 | put into the <envar>CLFS_HOST</envar> variable. To account for the
|
---|
| 19 | possibility that the host and target are the same arch, as cross-compiling
|
---|
| 20 | won't work when host and target are the same, part of the triplet needs to
|
---|
| 21 | be changed slightly to add "cross". Set <envar>CLFS_HOST</envar> using the
|
---|
| 22 | following command:</para>
|
---|
| 23 |
|
---|
| 24 | <screen os="b"><userinput>export CLFS_HOST="$(echo $MACHTYPE | \
|
---|
| 25 | sed "s/$(echo $MACHTYPE | cut -d- -f2)/cross/")"</userinput></screen>
|
---|
| 26 |
|
---|
| 27 | <para os="c">Now you will need to set the triplet for the target
|
---|
| 28 | architecture. Set the target variable using the following command:</para>
|
---|
| 29 |
|
---|
| 30 | <screen os="d"><userinput>export CLFS_TARGET="$MACHTYPE"</userinput></screen>
