6.11.1. Installation of Zlib
![[Note]](../images/note.png)
Note
Zlib is known to build its shared library incorrectly if
CFLAGS is specified in the
environment. If using a specified CFLAGS variable, be sure to add the -fPIC directive to the CFLAGS variable for the duration of the configure
command below, then remove it when building the static library.
Prepare Zlib for building the dynamic library:
./configure --prefix=/usr --shared --libdir=/lib
Compile the package:
make
To test the results, issue:
make check
Install the shared library:
make install
The previous command installed a .so
file in /lib. We will remove it and
relink it into /usr/lib:
rm -v /lib/libz.so ln -sfv ../../lib/libz.so.1.2.3 /usr/lib/libz.so
Build the static library:
make clean ./configure --prefix=/usr make
To test the results again, issue:
make check
Install the static library:
make install
Fix the permissions on the static library:
chmod -v 644 /usr/lib/libz.a
