5.3. Build Variables

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. You will need to set the CHOST triplet to match your particular needs. To set this information you can issue the following command:

export LFS_HOST="`echo ${MACHTYPE} | sed -e 's/unknown/cross/g' -e 's/-pc-/-cross-/g'`"

Now we will set our Target Triplet:

For a MIPS Little Endian Machine:

export LFS_TARGET="mips64el-unknown-linux-gnu"

For a MIPS Big Endian Machine:

export LFS_TARGET="mips64-unknown-linux-gnu"

Now we will add these to ~/.bashrc, just in case you have to exit and restart building later:

echo export LFS_HOST=\""${LFS_HOST}\"" >> ~/.bashrc
echo export LFS_TARGET=\""${LFS_TARGET}\"" >> ~/.bashrc
