gawk: Quick Installation

 
 B.2.1 Compiling 'gawk' for Unix-Like Systems
 --------------------------------------------
 
 The normal installation steps should work on all modern commercial
 Unix-derived systems, GNU/Linux, BSD-based systems, and the Cygwin
 environment for MS-Windows.
 
    After you have extracted the 'gawk' distribution, 'cd' to
 'gawk-4.2.1'.  As with most GNU software, you configure 'gawk' for your
 system by running the 'configure' program.  This program is a Bourne
 shell script that is generated automatically using GNU Autoconf.  (The
 Autoconf software is described fully starting with *note(Autoconf,
 autoconf,Autoconf---Generating Automatic Configuration Scripts)Top::.)
 
    To configure 'gawk', simply run 'configure':
 
      sh ./configure
 
    This produces a 'Makefile' and 'config.h' tailored to your system.
 The 'config.h' file describes various facts about your system.  You
 might want to edit the 'Makefile' to change the 'CFLAGS' variable, which
 controls the command-line options that are passed to the C compiler
 (such as optimization levels or compiling for debugging).
 
    Alternatively, you can add your own values for most 'make' variables
 on the command line, such as 'CC' and 'CFLAGS', when running
 'configure':
 
      CC=cc CFLAGS=-g sh ./configure
 
 See the file 'INSTALL' in the 'gawk' distribution for all the details.
 
    After you have run 'configure' and possibly edited the 'Makefile',
 type:
 
      make
 
 Shortly thereafter, you should have an executable version of 'gawk'.
 That's all there is to it!  To verify that 'gawk' is working properly,
 run 'make check'.  All of the tests should succeed.  If these steps do
 not work, or if any of the tests fail, check the files in the 'README_d'
 directory to see if you've found a known problem.  If the failure is not
 described there, send in a bug report (SeeBugs).
 
    Of course, once you've built 'gawk', it is likely that you will wish
 to install it.  To do so, you need to run the command 'make install', as
 a user with the appropriate permissions.  How to do this varies by
 system, but on many systems you can use the 'sudo' command to do so.
 The command then becomes 'sudo make install'.  It is likely that you
 will be asked for your password, and you will have to have been set up
 previously as a user who is allowed to run the 'sudo' command.
