Cross-Compiled Linux From Scratch - Version GIT-20170803-PowerPC64-Multilib

Chapter 10. Installing Basic System Software

10.20. Zlib-1.2.11 64 Bit

The Zlib package contains compression and decompression routines used by some programs.

10.20.1. Installation of Zlib

Prepare Zlib for compilation: 

CC="gcc -isystem /usr/include ${BUILD64}" \
CXX="g++ -isystem /usr/include ${BUILD64}" \
LDFLAGS="-Wl,-rpath-link,/usr/lib64:/lib64 ${BUILD64}" \
./configure \
    --prefix=/usr \
    --libdir=/usr/lib64

Compile the package: 

make

To test the results, issue: 

make check

Install the package: 

make install

The previous command installed two .so files into /usr/lib64. We will move them into /lib64 and then recreate a link in /usr/lib64: 

mv -v /usr/lib64/libz.so.* /lib64
ln -sfv ../../lib64/$(readlink /usr/lib64/libz.so) /usr/lib64/libz.so

Install the documentation: 

mkdir -pv /usr/share/doc/zlib-1.2.11
cp -rv doc/* examples /usr/share/doc/zlib-1.2.11

10.20.2. Contents of Zlib
