zlib 1.1.3 is a general purpose data compression library. All the code is thread safe.

For Unix: "configure; make test; make install" should work for most machines.

configure; make test
               *** zlib test OK ***

pkg=zlib
make -n install | tee ../../logs/$pkg.log.0
make install | tee ../../logs/$pkg.log.1

PAM is standard on Redhat and Debian Linux and on Solaris.

First thing to do (I assume you have successfully unpacked it!) is to run:

make check

# dir default.defs
lrwxrwxrwx   1 500      group1         16 Sep 28 11:49 default.defs -> defs/redhat.defs

Next, check the above symbolic link points to the file that best describes your system. Yes.

Second, try to compile it.

make

The first time you type make, it is likely to complain. This is to remind you to remove any libraries from previous versions of the distribution that are likely to confuse this make… Type 'make' again.

make

dir /etc/pam.conf

— not exist! so go ahead

pkg=pam
make -n install | tee ../../logs/$pkg.log.0
make install | tee ../../logs/$pkg.log.1
