Installation of Sh-utils

Before Sh-utils is installed, the sh-utils patch file may need to be applied. This patch is needed to avoid a conflict of variable names with certain Glibc versions (usually glibc-2.1.x) when compiling sh-utils statically. It is however safe to apply the patch even if you are running a different glibc version, so if you aren't sure, it's best to apply it.

Apply the patch by running the following command:

patch -Np1 -i ../sh-utils-2.0.patch

Install Sh-utils by running the following commands:

./configure --prefix=$LFS/usr --disable-nls &&
make LDFLAGS=-static &&
make install &&
cd $LFS/usr/bin &&
mv date echo false pwd stty $LFS/bin &&
mv su true uname hostname $LFS/bin
