Note that the -mstackrealign may cause build failures in non-Intel architecture systems. Compile the package: make To test the results, issue: make check Install the package: make install The shared library needs to be moved to /lib, and as a result the .so file in /usr/lib will need to be recreated: mv -v /usr/lib/libz.so.* /lib ln -sfv ../../lib/libz.so.&zlib-version; /usr/lib/libz.so Contents of Zlib Installed libraries libz.{a,so} Short Descriptions libz Contains compression and decompression functions used by some programs libz
