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 ${MACHTYPE} | sed "s/-[^-]*/-cross/")
export CLFS_TARGET=[target triplet]
export CLFS_CPU=[cpu type]
Table 4.1. Processor Type and Target Triplets
| Processor | Target Triplet | CPU Type | Note |
|---|---|---|---|
| 486 Compatibles | i486-linux-musl | i486 | Intel's i486 |
| Pentium, K6, 586 Compatibles | i586-linux-musl | i586 | Intel Pentium without MMX |
| Pentium II, Pentium III, Pentium 4 | i686-linux-musl | i686 | PentiumPro instruction set |
| Athlon | i686-linux-musl | athlon | AMD 32 bit Athlon |
| Opteron | x86_64-linux-musl | k8 | AMD K8 processors with x86-64 |
Now set the architecture of the CPU:
export CLFS_ARCH="x86"
Now we will add this to ~/.bashrc, just
in case you have to exit and restart building later:
echo export CLFS_HOST=\""${CLFS_HOST}\"" >> ~/.bashrc
echo export CLFS_TARGET=\""${CLFS_TARGET}\"" >> ~/.bashrc
echo export CLFS_ARCH=\""${CLFS_ARCH}\"" >> ~/.bashrc
echo export CLFS_CPU=\""${CLFS_CPU}\"" >> ~/.bashrc
