Rest of the LFS posts can be viewed here.

Below are the packages that I installed and the issues I faced:

Glibc

Error # 1

## configure: error: you must configure in a separate build directory
## Solution: 
cd /mnt/LFS/sources/glibc-2.40
# Create separate build directory
mkdir glibc-build && cd "$_"
# Configure with the correct prefix
../configure --prefix=/mnt/LFS/usr/include && make && make install

Error # 2

Update


After installing some packages I realised there are some env variables that are not set like **$LFS_TGT** because I didn't follow the rest of CH4 and went straight into compiling the packages ... I don't know how I missed the below part:

Create the required directory layout by issuing the following commands as root:

mkdir -pv $LFS/{etc,var} $LFS/usr/{bin,lib,sbin}
for i in bin lib sbin; do
ln -sv usr/$i $LFS/$i
done
case $(uname -m) in
x86_64) mkdir -pv $LFS/lib64 ;;
esac

Programs in Chapter 6 will be compiled with a cross-compiler (more details can be found in section Toolchain Technical Notes). This cross-compiler will be installed in a special directory, to separate it from the other programs. Still acting as root, create that directory with this command:

mkdir -pv $LFS/tools

The book advises against using the root user, so far I didn’t encounter issues but I’ll follow it’s recommendations anyways:

groupadd lfs
useradd -s /bin/bash -g lfs -m -k /dev/null lfs
passwd lfs ## If you wish to give the user a password
chown -v lfs $LFS/{usr{,/*},lib,var,etc,bin,sbin,tools}
case $(uname -m) in
x86_64) chown -v lfs $LFS/lib64 ;;
esac  
su - lfs # To log in as the new user
