%general-entities; ]> Setting Host and Target 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 $MACHTYPE | cut -d- -f2)/cross/")" Now you will need to set the triplet for the target architecture. Set the target variable using the following command: export CLFS_TARGET="[target triplet]" Replace [target triplet] with the appropriate machine triplet using the table at the bottom of the page. Copy settings to the Environment Now add these to ~/.bashrc, just in case you have to exit and restart building later: echo export CLFS_HOST=\""${CLFS_HOST}\"" >> ~/.bashrc echo export CLFS_TARGET=\""${CLFS_TARGET}\"" >> ~/.bashrc Processor Target Triplet 386 Compatibles Not Supported By Glibc 486 Compatibles i486-pc-linux-gnu Pentium, K6, 586 Compatibles i586-pc-linux-gnu Pentium II, Pentium III, Pentium 4 i686-pc-linux-gnu Athlon, Duron i686-pc-linux-gnu
