Package Information

Glibc Dependencies

Required

Binutils-2.46.0-pass1, GCC-15.2.0-pass1, and Linux-7.0.3-headers

2.4.1. Installation of Glibc

Prepare Glibc for compilation:

Patch a vulnerability, issue: 

patch -Np1 -i ../glibc-fhs-1.patch

Patch an issue with Linux 7.0, issue: 

patch -Np1 -i ../glibc-macro-guard.patch

Now Configure the Package, issue: 

case $(uname -m) in
    i?86)   ln -sfv ld-linux.so.2 $LFS/lib/ld-lsb.so.3
    ;;
    x86_64) ln -sfv ../lib/ld-linux-x86-64.so.2 $LFS/lib64
            ln -sfv ../lib/ld-linux-x86-64.so.2 $LFS/lib64/ld-lsb-x86-64.so.3
    ;;
esac

Now Coonfigure the Package, issue: 

mkdir -v build
cd build
echo "rootsbindir=/usr/sbin" > configparms

../configure --prefix=/usr \
             libc_cv_slibdir=/usr/lib \
             --build=$(../scripts/config.guess) \
             --enable-kernel=5.4 \
             --host=$LFS_TGT \
             --disable-nscd

To Compile the Package, issue: 

make

Now Install the Package, issue: 

make DESTDIR=$LFS install;
sed '/RTLDLIST=/s@/usr@@g' -i $LFS/usr/bin/ldd
