Installation of TCP Wrapper

Install TCP Wrapper with the following commands:

patch -Np1 -i ../tcp_wrappers-7.6-shared_lib_plus_plus-1.patch &&
sed -i -e "s,^extern char \*malloc();,/* & */," scaffold.c &&
make REAL_DAEMON_DIR=/usr/sbin STYLE=-DPROCESS_OPTIONS linux

This package does not come with a test suite.

Now, as the root user:

make install

Note : sed -i -e ... scaffold.c: This command removes an obsolete C declaration which causes the build to fail if using GCC >= 3.4.x.

that's it :)
