Nvi uses the GNU autoconf program for configuration and compilation.  You
should enter:

	../dist/configure
	make

and nvi will configure the system and build one or two binaries:  nvi and
tknvi.  You can use any path to the configure script, e.g., to build for
an x86 architecture, I suggest that you do:

	mkdir build.x86
	cd build.x86
	../dist/configure
	make

There are options that you can specify to the configure command.  See
the next section for a description of these options.

If you want to rebuild or reconfigure nvi, for example, because you change
your mind as to the curses library that you want to use, create a new
directory and reconfigure it using "configure" and whatever options you
choose, don't try to selectively edit the files.

By default, nvi is installed as "vi", with hard links to "ex" and "view".
To install them using different names, use the configure program options.
For example, to install them as "nvi", "nex" and "nview", use:

	configure --program-prefix=n

See the section below on installation for details.

Note, if you're building nvi on a LynxOS system, you should read the
README.LynxOS file in this directory for additional build instructions
that are specific to that operating system.

If you have trouble with this procedure, send email to the addresses
listed in ../README.  In that email, please provide a complete script
of the output for all of the above commands that you entered.

NVI'S OPTIONS TO THE CONFIGURE PROGRAM
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

There are many options that you can enter to the configuration program.
To see a complete list of the options, enter "configure --help".  Only
a few of them are nvi specific.  These options are as follows:

  --disable-re            DON'T use the nvi-provided RE routines.
  --enable-debug          Build a debugging version.
  --enable-perlinterp     Include a Perl interpreter in vi.
  --enable-tclinterp      Include a Tk/Tcl interpreter in vi.
  --enable-gtk		  Build a gtk front-end.
  --enable-motif	  Build a motif front-end.
  --enable-threads	  Turn on thread support.
  --enable-widechar	  Build a wide character aware vi (experimental).
  --with-curses=DIR       Path to curses installation.
  --with-db3=db3prefix    Path to db3 installation.
  --enable-dynamic-loading Load DB 3 dynamically.

disable-re:
	By default, nvi loads its own versions of the POSIX 1003.2 Regular
	Expression routines (which are Henry Spencer's implementation).
	If your C library contains an implementation of the POSIX 1003.2
	RE routines (note, this is NOT the same as the historic UNIX RE
	routines), and you want to use them instead, enter:

	--disable-re

	as an argument to configure, and the RE routines will be taken
	from whatever libraries you load.  Please ensure that your RE
	routines implement Henry Spencer's extensions for doing vi-style
	"word" searches.

enable-debug:
	If you want to build nvi with no optimization (i.e. without -O
	as a compiler flag), with -g as a compiler flag, and with DEBUG
	defined during compilation, enter:

	--enable-debug

	as an argument to configure.

enable-perlinterp:
	If you have the Perl 5 libraries and you want to compile in the
	Perl interpreter, enter:

	--enable-perlinterp

	as an argument to configure.  (Note: this is NOT possible with
	Perl 4, or even with Perl 5 versions earlier than 5.002.)

enable-tclinterp:
	If you have the Tk/Tcl libraries and you want to compile in the
	Tcl/Tk interpreter, enter:

	--enable-tclinterp

	as an argument to configure.  If your Tk/Tcl include files and
	libraries aren't in the standard library and include locations,
	see the next section of this README file for more information.

enable-gtk:
	If you have the Gtk libraries and you want to build the Gtk
	nvi front-end, enter:

	--enable-gtk

	as an argument to configure.  If your Gtk include files and
	libraries aren't in the standard library and include locations,
	see the next section of this README file for more information.
	See also the enable-threads option.

enable-motif:
	If you have the Motif libraries and you want to build the Motif
	nvi front-end, enter:

	--enable-motif

	as an argument to configure.  If your Motif include files and
	libraries aren't in the standard library and include locations,
	see the next section of this README file for more information.

enable-threads:
	If you want to be able to use multiple windows in the Gtk
	front-end, you should specify this option.

with-curses:
	Specifies the path where curses is installed.

with-db3:
	Specifies the path where DB3 is installed.
	See README.DB3 for more information about DB3.

enable-dynamic-loading:
	Dynamically load DB3 library.
	See README.DB3 for more information about DB3.

enable-widechar:
	Enables support for wide characters.
	Note that this is still rather experimental.

	If you try this out on Solaris, you will want to point nvi
	to the curses in /usr/xpg4/ which is CSI compliant.

=-=-=-=-=-=-=
ADDING OR CHANGING COMPILERS, OR COMPILE OR LOAD LINE FLAGS
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

If you want to use a specific compiler, specify the CC environment
variable before running configure.  For example:

	env CC=gcc configure

Using anything other than the native compiler will almost certainly
mean that you'll want to check the compile and load line flags, too.

If you want to specify additional load line flags, specify the ADDLDFLAGS
environment variable before running configure.  For example:

	env ADDLDFLAGS="-Q" configure

would specify the -Q flag in the load line when the nvi programs are
loaded.

If you don't want configure to use the default load line flags for the
system, specify the LDFLAGS environment variable before running configure.
For example:

	env LDFLAGS="-32" configure

will cause configure to set the load line flags to "-32", and not set
them based on the current system.

If you want to specify additional compile line flags, specify the
ADDCPPFLAGS environment variable before running configure.  For example:

	env ADDCPPFLAGS="-I../foo" configure

would cause the compiler to be passed the -I../foo flag when compiling
test programs during configuration as well as when building nvi object
files.

If you don't want configure to use the default compile line flags for the
system, specify the CPPFLAGS environment variable before running configure.
For example:

	env CPPFLAGS="-I.." configure

will cause configure to use "-I.." as the compile line flags instead of
the default values.

=-=-=-=-=-=-=
ADDING LIBRARIES AND INCLUDE FILES
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

If the Tk/Tcl or any other include files or libraries are in non-standard
places on your system, you will need to specify the directory path where
they can be found.

If you want to specify additional library paths, set the ADDLIBS environment
variable before running configure.  For example:

	env ADDLIBS="-L/a/b -L/e/f -ldb" configure

would specify two additional directories to search for libraries, /a/b
and /e/f, and one additional library to load, "db".

If you want to specify additional include paths, specify the ADDCPPFLAGS
environment variable before running configure.  For example:

	env ADDCPPFLAGS="-I/usr/local/include" LIBS="-ldb" configure

would search /usr/local/include for include files, as well as load the db
library as described above.

As a final example, let's say that you've downloaded ncurses from the net
and you've built it in a directory named ncurses which is at the same
level in the filesystem hierarchy as nvi.  You would enter something like:

	env ADDCPPFLAGS="-I../../ncurses/include" \
	    ADDLIBS="-L../../ncurses/libraries" configure

to cause nvi to look for the curses include files and the curses library
in the ncurses environment.

Notes:
	Make sure that you prepend -L to any library directory names, and
	that you prepend -I to any include file directory names!  Also,
	make sure that you quote the paths as shown above, i.e. with
	single or double quotes around the values you're specifying for
	ADDCPPFLAGS and ADDLIBS.

	=-=-=-=-=-=
	You should NOT need to add any libraries or include files to load
	the Perl5 interpreter.  The configure script will obtain that
	information directly from the Perl5 program.  This means that the
	configure script must be able to find perl in its path.  It looks
	for "perl5" first, and then "perl".  If you're building a Perl
	interpreter and neither is found, it's a fatal error.

	=-=-=-=-=-=
	You do not need to specify additional libraries to load Tk/Tcl,
	Perl or curses, as the nvi configuration script adds the
	appropriate libraries to the load line whenever you specify
	--enable-tknvi or other Perl or Tk/Tcl related option, or build
	the Tk/Tcl or curses version of nvi.  The library names that are
	automatically loaded are as follows:

	for Perl:	-lperl
	for Tk/Tcl:	-ltk -ltcl -lm
	for curses:	-lcurses

	In addition, the configure script loads:

		... the X libraries when loading the Tk/Tcl libraries,
		    if they exist.

		... the -ltermcap or -ltermlib libraries when loading
		    any curses library, if they exist.

	=-=-=-=-=-=
	The env command is available on most systems, and simply sets one
	or more environment variables before running a command.  If the
	env command is not available to you, you can set the environment
	variables in your shell before running configure.  For example,
	in sh or ksh, you could do:

		ADDLIBS="-L/a/b -L/e/f -ldb" configure

	and in csh or tcsh, you could do:

		setenv ADDLIBS "-L/a/b -L/e/f -ldb"
		configure

	See your shell manual page for further information.

=-=-=-=-=-=-=
INSTALLING NVI
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Nvi installs the following files into the following locations, with
the following default values:

Variables:		Default value:
prefix			/usr/local
exec_prefix		$(prefix)
bindir			$(prefix)/bin
datadir			$(prefix)/share
mandir			$(prefix)/man

File(s):		Default location
----------------------------------------
vi			$(bindir)/vi
vi.1			$(mandir)/man1/vi.1
vi.0			$(mandir)/cat1/vi.0
Perl scripts		$(datadir)/vi/perl/
Tcl scripts		$(datadir)/vi/tcl/
Message Catalogs	$(datadir)/vi/catalog/

Notes:
	There are two hard links to the vi program, named ex and view.
	Similarly, there are two hard links to the unformatted vi manual
	page, named ex.1 and view.1, and two hard links to the formatted
	manual page, named ex.0 and view.0.  These links are created when
	the program and man pages are installed.

	If you want to install vi, ex, view and the man pages as nvi, nex,
	nview, use the configure option --program-prefix=n.  Other, more
	complex transformations are possible -- use configure --help to
	see more options.

	To move the entire installation tree somewhere besides /usr/local,
	change the value of both "exec_prefix" and "prefix".  To move the
	binaries to a different place, change the value of "bindir".
	Similarly, to put the datafiles (the message catalogs, Perl and
	Tcl scripts) or the man pages in a different place, change the
	value of "datadir" or "mandir".  These values can be changed as
	part of configuration:

		configure --exec_prefix=/usr/contrib --prefix=/usr/share

	or when doing the install itself:

		make exec_prefix=/usr/contrib prefix=/usr/contrib install

	The datafile directory (e.g., /usr/local/share/vi by default) is
	completely removed and then recreated as part of the installation
	process.

=-=-=-=-=-=-=
NVI AND THE CURSES LIBRARY
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

The major portability problem for nvi is selecting a curses library.
Unfortunately, it is common to find broken versions of curses -- the
original System V curses was broken, resulting in all vendors whose
implementations are derived from System V having broken implementations
in turn.

If you use the vendor's or other curses library, and you see any of the
following symptoms:

	+ Core dumps in curses routines.
	+ Missing routines when compiling.
	+ Repainting the wrong characters on the screen.
	+ Displaying inverse video in the wrong places.
	+ Failure to reset your terminal to the correct modes on exit.

you have a broken curses implementation, and you should reconfigure nvi
to use another curses library.

An alternative for your vendor's curses is ncurses, available from
ftp://ftp.gnu.org/pub/gnu/ncurses/

One final note.  If you see the following symptoms:

	+ Line-by-line screen repainting instead of scrolling.

it usually means that your termcap or terminfo information is insufficient
for the terminal.

0. Introduction
---------------

This file describes how to build and install the Berkeley nvi editor for
the LynxOS 2.4.0 operating system.

LynxOS 2.4.0 is available for a variety of different hardware platforms, in
particular, x86, m680x0, Sparc, and PowerPC.  I have successfully built nvi
on all four of these flavors of LynxOS by following the procedures given in
this file.

Note that these procedures may not work on versions of LynxOS prior to 2.4.0.
(As I understand it, a good deal of work went into making the 2.4.0 release
more POSIX-compliant, and I have no idea what build glitches, if any, you
might encounter if you try to build nvi on a pre-2.4.0 version of LynxOS.)

There are basically four steps to configuring, building, and installing nvi
on LynxOS, namely:

	1.  Get setup to use the proper C compiler.
	2.  Replace your installed `tr' program.
	3.  Fix your system include files.
	4.  Do a normal configure, build, and install of nvi.

These steps are described in separate sections below.

1.  Get Setup to Use the Proper C Compiler
------------------------------------------

The first step when building nvi on LynxOS is to set your $PATH environment
variable properly so that the gcc 2.x compiler appears first on your path,
prior to the older (and less robust) gcc 1.xx compiler (typically installed
as /bin/gcc) and/or the old Lynx proprietary C compiler (typically installed
as /bin/cc), both of which may also be present on your system.

Note that for most operating systems, the configure script for nvi tries
to use whatever compiler you have installed (and in your $PATH) as "cc",
however in the special case of LynxOS, the configure script will auto-
matically try to find a "gcc" program on your $PATH in preference to a
compiler called "cc".  If the nvi configure script only find a compiler
called "cc", that's OK.  It will still try to see if that is really just
the GNU C compiler installed under the name "cc".

Regardless of the name however (be it "gcc" or "cc") the first C compiler
in your $PATH should be some _recent_ (i.e. 2.0 or later) version of the
GNU C compiler... and the nvi configure script now checks that this is the
case, and fails if it isn't.

Oddly enough, LynxOS 2.4.0 (and some prior versions) shipped with as many
as three different C compilers installed, so it is important to set your
$PATH environment variable carfully in order to get the proper C compiler
to appear first in your $PATH.  You want to avoid having either the /bin/gcc
compiler or the /bin/cc compiler be the first C compiler in your $PATH.

To make sure that the GNU C version 2.x compiler which was shipped with your
LynxOS system appears first on your path, you will need to either set your
$PATH variable (for sh/bash/ksh users) or your $path variable (for csh/tcsh
users).  You can, of course, just do this at the shell command prompt, but
it is probably better to actually edit this change into your .profile file
(for sh/bash/ksh users) or into your .cshrc file (for csh/tcsh users).

The pathname of the directory that contains the GNU C version 2.x compiler
is (unfortunately) dependent upon the exact type of LynxOS system you have.

For LynxOS 2.4.0 on x86 systems, gcc 2.x is located in:

	/cygnus/94q4-lynxos-x86/bin

For LynxOS 2.4.0 on m680x0 systems, gcc 2.x is located in:

	/cygnus/94q4-lynxos-68k/bin

For LynxOS 2.4.0 on Sparc systems, gcc 2.x is located in:

	/cygnus/94q4-lynxos-usparc/bin

For LynxOS 2.4.0 on PowerPC systems, gcc 2.x is located in:

	/cygnus/95q2-lynxos-ppc/bin

(Note also that these locations may change in LynxOS 2.5.x and beyond.)

Anyway, it is imperative that you setup your $PATH environment variable
(*before* you do the configure step for nvi) so that the GNU C version 2.x
compiler appears in your $PATH before either the /bin/cc or /bin/gcc
compilers (if present).  If you fail to do this, the configure step for
nvi will fail, because the compiler script actually checks (now) that the
compiler you are using (if your are on a LynxOS system) is gcc 2.0 or
later.

To make absolutely sure that you will be configuring and building nvi with
the proper C compiler (i.e. the GNU C version 2.x compiler on your system)
you should add the directory name listed above for your specific system type
to your $PATH setting in your $HOME/.profile file.  (For csh/tcsh users, you
will instead want to add the relevant directory name to the setting of your
$path variable in your ~/.cshrc file.)  Once you have added the proper direc-
tory name (from the list given above) to your $HOME/.profile file (or to your
~/.cshrc file, if you are using csh or tcsh) you should log out completely
and then log back into the system just to make sure your new $PATH/$path
setting takes effect properly.

When you finish making this adjustment to your $PATH (or $path), the most
up-to-date version of gcc on your system should be available to you as the
first `gcc' program on your $PATH.  You should verify that this is indeed the
case simply by typing `gcc -v' and then checking the version number reported
by the compiler.  It should say either "2.6-94q4" or (on PowerPC systems) it
should say "2.6-95q2".  If you don't get these results, try again to set your
$PATH (or $path) until you do.  You won't be able to build nvi until you are
properly setup to use gcc version 2.0 or later.

Performing the steps shown above will insure that your subsequent configura-
tion and build steps for nvi will make use of the most up-to-date version of
gcc that was shipped with your Lynx operating system.  (Note that the versions
of gcc which are currently shipping with LynxOS 2.4.0 are also somewhat out-
of-date themselves, but they are still quite a bit newer and more bug-free
and ANSI conformant that those other two C compilers, /bin/cc and /bin/gcc,
which also ship with LynxOS 2.4.0.)

(Note:  At present, LynxOS version 2.4.0 is the latest officially released
version of LynxOS, and all of the above information is accurate and correct
for LynxOS 2.4.0 as of the time of this writing.  However it is rumored that
future releases of LynxOS may provide a still newer version of gcc, and that
it may be located in the /usr/bin directory.  Thus, if you are building nvi
for some LynxOS version later than 2.4.0, you may wish to check and see if
your system has a program called /usr/bin/gcc, and use that version of gcc,
if available, rather than the one suggested above.)

2.  Replace Your Installed `tr' Program
---------------------------------------

The `tr' program which comes bundled with LynxOS 2.4.0 (as /bin/tr) has a
somewhat obscure bug which just happens to be tickled by almost all GNU
`autoconf' generated `configure' scripts (including the one that nowadays
comes bundled with nvi).  Using the stock /bin/tr program on LynxOS when
executing such `configure' scripts _will_ cause these scripts to malfunction
in various ways.  It is therefore imperative that you replace your LynxOS
/bin/tr program with a properly working version of the `tr' command _before_
you even try to configure nvi.  (You can tell if your `tr' program has the
bug by executng the command "echo ab- | tr ab- ABC".  If this yields the
string "Ab-" then you have the bug.  If it yields "ABC" then you don't.)

You can obtain sources for a working version of the `tr' command as part of
the GNU `textutils' package (the latest version of which, at the time of this
writing, is 1.19).  The GNU textutils package is available for downloading
from prep.ai.mit.edu in the pub/gnu directory.  Look for the file named
textutils-1.19.tar.gz, or an even more recent version of textutils, if one
is available.  Fetch it, gunzip it, untar it, and follow the directions in
the INSTALL file included in the tar file to build and install the entire
textutils set of utility programs (which includes a working `tr' program).
Then just make sure that the GNU version of `tr' appears on your $PATH
_before_ the LynxOS version of `tr' (i.e. /bin/tr).  Be sure to do this
step _before_ you start to configure nvi.

When building the textutils set of programs, I suggest that you use the most
up-to-date C compiler available on your system (as described above).  Also,
note that it will be important for you to AVOID using the -O (optimize)
compiler option when building the GNU textutils package, even if you are
using the most up-to-date version of gcc which shipped with your system.
If you try to use -O when building the textutils package on an x86 with
the Cygnus 94q4 C compiler, you will end up with a `tr' program which will
malfunction even worse than the one you are trying to replace!  If you use
-O when building the textutils package on LynxOS on the PowerPC (using the
Cygnus 95q2 C compiler) you will just get yourself a compiler crash.  So
just don't use -O when building textutils.  You can avoid using -O by in-
voking make in the textutils directory as follows:

	make CFLAGS="-g"

(Note:  At present, LynxOS version 2.4.0 is the latest officially released
version of LynxOS, and all of the above information is accurate and correct
for LynxOS 2.4.0 as of the time of this writing.  However it is rumored that
the bug in the /bin/tr program will be fixed in future releases of LynxOS,
so if you have a version of LynxOS later than 2.4.0, you may wish to check
and see if your /bin/tr program even has the problematic bug before bothering
with all of this.)


3.  Fix Your System Include Files
---------------------------------

If you are building nvi on a PowerPC system, it is also important that you
apply the patches given at the end of this file to your /usr/include files.
(Note that you will have to be root in order to do this.)  Two of the patches
included below fix a pair of serious bugs in the /usr/include/stdarg.h file
on the PowerPC, and you really _do_ want to have these bugs fixed anyway,
because without these fixes, anything that you compile which uses <stdarg.h>
will very likely malfunction at run-time.

Regardless of which LynxOS platform you are using (i.e. x86, PowerPC, Sparc,
or m680x0) you may want to apply all of the system include files patches that
are included below anyway.  Doing so will clean up a few minor problems with
the relevant system include files (i.e. <stdarg.h>, <ioctl.h>, and <wait.h>)
and this step will also prevent a few warnings which you would otherwise get
during the build of nvi.

You can apply all of the patches given at the end of this file simply by
doing the following:

	su root
	cd /usr/include
	/bin/patch < this-file

Where `this-file' is the actual full pathname of the file you are now reading,
wherever it may reside on your own system.

(Note:  At present, LynxOS version 2.4.0 is the latest officially released
version of LynxOS, and all of the above information is accurate and correct
for LynxOS 2.4.0 as of the time of this writing.  However it is rumored that
future releases of LynxOS may incorporate some or all of the important system
include file fixes provided below.  Thus, if you are building nvi for some
LynxOS version later than 2.4.0, you should probably go ahead and try to
apply the patches given below to your system include files, and then just
don't worry about it if these patches seem to have already been applied.)


4.  A Brief Note about Sendmail
-------------------------------

I should mention also that LynxOS does not normally ship with the `sendmail'
mail transfer program installed, either under /usr/lib/ or anywhere else for
that matter.  This isn't really a big problem, but nvi normally wants and
expects to have a sendmail program available so that it can send users notifi-
cations (by mail) whenever a partially edited file is preserved by the editor
in response to a sudden system crash, a sudden system shutdown, or an unexpect-
ed serial-line hangup.  You can configure and build nvi without any sendmail
program installed on your system, but you will get warnings about its absence
when you are doing the initial configure step prior to actually building nvi.
If you want to have a fully-functional nvi which does send out notification
messages (by mail) whenever partially edited files are preserved during a
serial line hangup or system crash, then you should get the BSD sendmail
sources (via ftp from ftp.cs.berkeley.edu), build and install sendmail, and
then reconfigure, rebuild, and reinstall nvi.

Please contact me at the E-mail address below if you experience any problems in
building or using nvi on LynxOS.  I make no guarrantees, but I may be willing
to try to help.

There are some known problems with Solaris curses.
Please give ncurses a try when you encounter a screen output problem.

Apparently, the more recent Solaris compilers invoke the incremental linker,
`ild', when the "-g" option is used and one or more "xxx.o" files are
specified on the command line during the link phase.  Unfortunately, the
executable produced is up to 3-4 times as big as an executable generated
by the standard linker `ld'.
You can bypass this by adding "-xildoff" to LDFLAGS or by
setting CFLAGS (to something that does not contain "-g").
