          Nmap-7.98 (with a symbolic link nc pointing to ncat in /usr/bin; used in tests)
        
To run the tests, the following option should be enabled in the kernel configuration:
General setup ---> [*] POSIX Message Queues [POSIX_MQUEUE]
Install lsof by running the following commands:
./configure --prefix=/usr --disable-static && make
          The tests should be run as the root
          user. They require that the POSIX message queues are enabled in the
          kernel, and that Nmap-7.98 be installed with a symbolic link
          /usr/bin/nc pointing to ncat.
        
make check
          Now, as the root user:
        
make install
          --disable-static: This
          switch prevents installation of static versions of the libraries.
