//usr/share/doc/perl-Curses-1.28/INSTALL

This package requires at least perl5.005.  You're on your own before
then.

1) Make sure you've got the prerequisites

1.1) Make sure perl has been built.

1.2) Make sure you have a Curses C library installed.  Either original 
     BSD Curses or newer Ncurses will do.  Pdcurses (public domain Curses
     code that works in DOS, Windows, and X11) almost works.  See
     PDCURSES section below.

2) Chdir into the Curses source directory (which you unpacked from the
   .tgz file you downloaded from CPAN)

3) Want to see if maybe the package can autoconfigure itself?  It's
   pretty dumb about it, but give it a try and skip to (5).

4) Configure the build for your system.

4.1)

Look in the "hints" directory to see if any of the hint files are
   appropriate to your machine's OS.  If so, symlink or copy it to the
   file "c-config.h" in the current ("Curses") directory.  If not,
   copy "hints/c-none.h" to "c-config.h" in the current directory.
   Then edit "c-config.h" and follow the directions.  If you have to
   "roll your own", be sure to save a copy.  A "make clean" will
   delete "c-config.h".  If you "rolled your own", please send me a
   copy so I can include it in future distributions (see
   "hints/c-isc.h" for an example of a user-contributed "c-config.h").

4.2)

Curses has an interface header file named form.h.  If on your system
   this is in a system header file directory such as /usr/include, you
   have a problem.  That's because Perl also has a file named form.h
   in a directory that is searched before the system directories in the
   compile of the Perl Curses module.

So you'll have to fix that.  It's better to have your Curses stuff
   in its own directory.  /usr/include/ncurses is conventional.  Move
   all your Curses header files (curses.h, ncurses.h, form.h, menu.h,
   panel.h) into this directory.  If you use /usr/include/ncurses,
   Makefile.PL will find them there.  Otherwise, set the _CFLAGS
   environment variables below accordingly.

Alternatively, you can just edit c-config.h, after running
   Makefile.PL.  Replace the line

#include <form.h>

with something like

#include "/usr/include/form.h"

explicitly specifying the Ncurses version of form.h.

You can ignore all this if you're not building forms capability
   into the Perl Curses module (by specifying "FORMS" as an option to
   Makefile.PL below).

4.3)

Set environment variables telling the compiler and linker where your
   Curses C libraries are:

CURSES_CFLAGS: -I and -D options needed at compile time for access to
        the basic Curses library (libcurses).
      CURSES_LDFLAGS: -L and -l options needed at link time for access to 
        the basic Curses library (libcurses).  (this really
        must be only -L and -l options; Makefile.PL parses it.  Furthermore,
        there can't be any space between the -L or -l and its value).

CURSES_PANEL_CFLAGS
      CURSES_PANEL_LDFLAGS
      CURSES_MENU_CFLAGS
      CURSES_MENU_LDFLAGS
      CURSES_FORM_CFLAGS
      CURSES_FORM_LDFLAGS

These are analogous, but for the panel, menu, and form specialty
      Curses libraries, respectively.

You can set these in your shell and export them, e.g.

export CURSES_CFLAGS="-I/usr/include/ncurses"
      export CURSES_LDFLAGS="-L/usr/lib/ncurses -lncurses"

Or you can set them right on the 'perl Makefile.PL' command.

5) perl Makefile.PL [PANELS] [MENUS] [FORMS]  [options]

PANELS means to include Curses panel function.

MENUS means to include Curses menu functions.

FORMS means to include Curses form function.

For PANELS, MENUS, and FORMS, you must have the associated C library on
   your system (libpanel, libmenu, libform).  Choosing one of these options
   without having the library will prevent this package from compiling.

Currently, PANELS, MENUS, and FORMS don't work for the BSD 
   hints files (c-*.bsd.h), because I'm not aware of any panel, menu,
   or form libraries for BSD curses.

This package needs the perl header files.  If you've already
   installed perl, the "Makefile.PL" will magically know where they
   are.  If you haven't installed perl, you may need to tell the
   "Makefile.PL" where the header files are.  You can do this with the
   "PERL_SRC=<source directory>" option.

perl Makefile.PL PERL_SRC=/local/src/perl

The "Makefile.PL", as with just about every other perl module, uses
   the "ExtUtils::MakeMaker" package to generate a make file (named
   "Makefile").  I highly recommend reading the "ExtUtils::MakeMaker"
   man page, as there are lots of neat options you can specify.

If Makefile.PL tells you that it can't do something (it prints out
   "I'm sorry" and some more stuff), then you'll need to go back to
   step (4) and try configuring by hand.

6) make

`make' will first run a perl script called `test.syms' that investigates
   what the Curses libraries are like on your system and records the
   results in the file "CursesDef.h".

test.syms is very brittle -- it works via test compiles, and if any
   number of things goes wrong with the test compile, it makes bad
   assumptions, usually that you don't have a certain function in your
   Curses library.  If test.syms tells you it can't find functions that
   you think you have, run test.syms manually with the -v (verbose) option.
   That will show you the error messages from the test compiles and you
   can figure out what's going wrong and fix it.  Typically, you'll find
   that you need to do better on your CURSES_* environment variables
   (see above).

Alternatively, if you see that test.syms is picking the wrong
   values, you can edit "CursesDef.h" by hand and follow the
   directions.  If you have to "roll your own", be sure to save a
   copy.  A "make clean" will delete "CursesDef.h".

`make' will then try to compile "Curses.c".  If you get any
   undefined curses symbols, it means that your curses really doesn't
   have those functions, and you should edit "CursesDef.h" and/or
   "c-config.h" and change the #define to #undef for that function.

If you get other compile errors, it is probably because the curses
   include file and the perl include files are conflicting.  You'll
   have to figure out what's wrong and add proper C code to
   "c-config.h".  See "hints/c-sunos.sysv.h" for an example of how to
   do this.

7) Test the distribution:

perl demo
   perl gdc
   perl demo2       [stuff that has a 50/50 chance of showing up right]
   perl demo.panel  [if you enabled panel function]
   perl demo.menu   [if you enabled menu function]
   perl demo.form   [if you enabled form function]

"gdc" is a digital clock ported from the "ncurses" distribution.

As mentioned in the "README", the demo is not intended to be an
   exhaustive test of all the possible Curses functions.  If it
   doesn't do all the functions correctly, it may be a Curses bug or
   it may be a problem with your system's "libcurses.a".  There's no
   getting around the fact that you need to be conversant in how your
   system's "libcurses.a" works to be able to use Curses most
   effectively.

For "demo", you can try:

make cdemo

This will try to compile a pure-C version of the "demo".  If you
   see the same errors in it that you see in "demo", it means there's
   a bug in your libcurses.
   
8) Doing a :

make install

will install everything in the "standard" perl places, just like
   stuff from the base perl distribution.

9) Enjoy!

If your enjoyment is ruined (:-) because the module doesn't work
   right, peruse the Curses pod document (located at the end of
   "Curses.pm") for incompatibilities with other Perl programs.  Also
   check the end of the "README" for problems that may exist for your
   particular libcurses.a or operating system.

HP-UX
-----

HP-UX has two Curses libraries.  According to HP:

Libraries libcur_colr.a and libcur_colr.sl, and commands
  captoinfo_colr, infocmp_colr, tput_colr, and tic_colr are
  part of HP-UX Color-Curses package used for color-management.

And there is apparently also a library with the standard names.
The Curses Perl module builds using the standard library by default.
If you want to use the "color" versions, set the CURSES_CFLAGS and
CURSES_LDFLAGS environment variables accordingly.

HP recommends using the HP ANSI C compiler for everything but
compiling the kernel, but the one for compling the kernel is the
default.  (Seems ridiculous, but an HP user said so).  I don't know
what difference it makes for the Perl Curses module, but if you
want to use the ANSI compiler, add this to Makefile.PL's arguments:

CC=/opt/ansic/bin/cc

PDCURSES
--------

Pdcurses is a public domain Curses implementation that works on DOS,
OS/2, Win32, and X11.  http://pdcurses.sourceforge.net .

Dave C reported success using Perl Curses with Pdcurses on Windows
in September 2007.  He gave these notes:

Environment:
    Perl Version 5.8.1 built for MSWin32-x86-multi-thread
    MSVS 2003 Visual C++ 7
    Windows XP
    Perl module Curses-1.16
    Pdcurses 3.3

Instructions:

- Set environment variables (for Perl Curses Makefile.PL):

CURSES_CFLAGS='-Ic:\dev\pdc33'
      CURSES_LDFLAGS='-Lc:\dev\pdc33 pdcurses.lib'
    
  -  Build and Test

> Makefile.PL
       > nmake test

ignore MOUSE_MOVED redefined warning
       MOUSE_MOVED is never used in Curses 1.16

- Install:

> nmake install

- Test:

demo, demo2, demo.panel scripts successfully run

> nmake cdemo
       > cdemo

Alexandr Ciornii on September 22, 2006, reported that he had some success
using Perl Curses with Pdcurses, with these notes:

I've encountered several problems with it:
    
    1. 'pdcurses.h' does not exist; only 'curses.h'.  Renamed it.
    2. 'curses.h' also defines chtype and attr_t.  Commented out there.
    3. 'curses.h' also defines SCREEN.  Commented out in 'CursesTyp.h'.
    4. `perl demo` fails
    
        Curses function 'TIESCALAR' called with too few arguments at
        C:\cpan\Curses-1.14\blib\lib/Curses.pm line 82.
        Compilation failed in require at demo line 11.
