%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. You will need to set the target triplet for the target architecture, and the CPU type. If you do not know what triplet or CPU type you want, you can use the table as a reference. Set the command using the method listed below: export CLFS_HOST=$(echo ${MACHTYPE} | sed "s/-[^-]*/-cross/") export CLFS_TARGET=[target triplet] export CLFS_CPU=[cpu type] Processor Target Triplet CPU Type Note 486 Compatibles i486-pc-linux-musl i486 Intel's i486 Pentium, K6, 586 Compatibles i586-pc-linux-musl i586 Intel Pentium without MMX Pentium II, Pentium III, Pentium 4 i686-pc-linux-musl i686 PentiumPro instruction set Athlon i686-pc-linux-musl athlon AMD 32 bit Athlon Opteron x86_64-unknown-linux-musl k8 AMD K8 processors with x86-64 Now we will set the architecture of the CPU based on the target triplet provided above: export CLFS_ARCH=$(echo ${CLFS_TARGET} | sed -e 's/-.*//' -e 's/i.86/i386/') Now we will add this to ~/.bashrc, just in case you have to exit and restart building later: echo export CLFS_HOST=\""${CLFS_HOST}\"" >> ~/.bashrc echo export CLFS_TARGET=\""${CLFS_TARGET}\"" >> ~/.bashrc echo export CLFS_ARCH=\""${CLFS_ARCH}\"" >> ~/.bashrc echo export CLFS_CPU=\""${CLFS_CPU}\"" >> ~/.bashrc
