During the building of the cross-compile tools you will need to set a
few variables that will be dependent on your particular needs. The
first variable will be the triplet of the host machine, which will be
put into the CLFS_HOST
variable. To
account for the possibility that the host and target are the same
arch, as cross-compiling won't work when host and target are the
same, part of the triplet needs to be changed slightly to add
"cross". Set CLFS_HOST
using the following
command:
export CLFS_HOST="$(echo $MACHTYPE | \ sed "s/$(echo $MACHTYPE | cut -d- -f2)/cross/")"
Now you will need to set the triplet for the target architecture. Set the target variable using the following command:
export CLFS_TARGET="[target triplet]"
Replace [target triplet] with the appropriate machine triplet using the table at the bottom of the page.
Now add these to ~/.bashrc
, just in
case you have to exit and restart building later:
cat >> ~/.bashrc << EOF export CLFS_HOST="${CLFS_HOST}" export CLFS_TARGET="${CLFS_TARGET}" EOF
