6.9.3. Contents of Zlib
Installed libraries:
libz.[a,so]
The Zlib package contains compression and decompression routines used by some programs.
This package requires compiler variables to be set for the target in the environment.
export CC="${CLFS_TARGET}-gcc"
export CXX="${CLFS_TARGET}-g++"
export AR="${CLFS_TARGET}-ar"
export AS="${CLFS_TARGET}-as"
export RANLIB="${CLFS_TARGET}-ranlib"
export LD="${CLFS_TARGET}-ld"
export STRIP="${CLFS_TARGET}-strip"
This patch will add -fPIC to our build and allow us to build a static and shared library at the same time:
patch -Np1 -i ../zlib-1.2.3-fPIC-2.patch
Prepare Zlib for compilation:
./configure --prefix=/usr --shared
Compile the package:
make
Install the package:
make prefix=${CLFS}/usr install
The previous command installed a .so
file in ${CLFS}/usr/lib. We will move
it into ${CLFS}/lib and then relink
it to ${CLFS}/usr/lib:
mv -v ${CLFS}/usr/lib/libz.so.* ${CLFS}/lib
ln -sfv ../../lib/libz.so.1 ${CLFS}/usr/lib/libz.so
Now we fix the permissions on the static library:
chmod -v 644 ${CLFS}/usr/lib/libz.a
