   II. Installing a Binary Distribution


B. Compiling/Installing the Source Distribution



	A. Installation Details:
	------------------------

* Introduction:
  ------------
  LyX and related programs have been ported from UNIX, following
  the UNIX design philosophy to do complex tasks combining small 
  external standard utilities. 
  UNIX is designed as a multi user system, where a professional
  system administrator maintains applications. On a single user 
  workstation the user has to do this complicated job. Often
  programs assume you are familiar with the details of the UNIX
  standard. Even if documentation therefore seems complicated,
  you should try to read all the documents, UNIX manual (man) 
  pages and FAQ a program supplies.


  I. Requirements/Optional Software:
     ------------------------------

1) XFree86 for OS/2
   ----------------

   Use only a current version. Check 

	http://www-set.gmd.de/~veit/os2/xf86os2.html

  An OS/2 specific FAQ answering most of the questions about 
  using XFree86/2 is found always up to date at:

	http://www-set.gmd.de/~veit/os2/xf86os2.html


2) 'xpm.dll' library (if indicated in README.bin)
   -----------------

   Check hobbes for 'xpm', or:

	http://set.gmd.de/~veit/os2/xf86plib.html

3) 'sed' and 'GNU utilities' (Option)
   -------------------------
   - Required: 'sed.exe'

   - Optional: 'groff.exe' for ASCII text export, 'GNU text 
     utilities', 'man' to read man/man1/lyx.1. 

   You can search for OS/2 ports of those standard UNIX utilities on:

	Hobbes or ftp.leo.org 

   in unix or gnu directories. Put the executables into a directory
   in PATH, e. g.:

	d:\bin 
   (Hint: Often ports assume a UNIX-like 'sh.exe' in '\bin'!)

    and put the dll's into a directory in LIBPATH.


4) 'LaTeX' and 'dvips' (Option)
   -------------------

   You will need them for printable output. With emTeX make sure that
   you have latex2e.cmd in \emtex\bin-directory. If it is missing (i.
   e. if you installed emtex from emtex-bin-os2.zip) create it using 
   the following commands from \emtex\doc\english:

	cd \emtex\btexfmts
	makefmt 386 latex2e US 8bit -b \emtex\bin\latex2e

   Now you can print US-english text. If LyX cannot find the files
   'latex.cmd' or 'latex2e.cmd' (available if your LaTeX is installed 
   correctly) it will work with standard options. Then you can use it
   as an editor to write files in native (*.lyx) and LaTeX (*.tex) 
   format. You can later print LaTeX files on every system with a
   proper LaTeX2e installation (or send them to your editor).

 * A preconfigured version of emTeX may be found searching:

	http://tsikora.tiac.net/os2/os2-body.html
	
   for 'emTeX'. Install first 'emTeX' and then unzip 'dvips583' into 
   your emtex root directory.

 * Additional TeX macros for special purposes (e. g. Babel) are
   available on your local CTAN mirror. There you will find also the
   documentation how to install it. Please read Help->LaTeXconfig for 
   availability of the LaTeX packages after installing LyX. 

   Babel is - unlike with almost all other recent TeX distributions -
   not standard with emTeX. For non-US languages you can install Babel
   and recreate the LaTeX format files with the correct languages 
   after selected, reading the respective original documentation. All 
   further problems should be discussed with the author (Eberhard 
   Mattes) and on emTeX list. 

 * In Germany I recommend:

ftp://ftp.dante.de/tex-archive/help/Catalogue/catalogue.html

   as the starting point for browsing CTAN. Dvips is also available
   on:

http://www.leo.org/pub/comp/os/os2/leo/emTeX/contrib/index.html.


   

5) 'Xdvi', 'gs', 'ghostview' or 'gv' with 'xaw3d' (Options)
   ----------------------------------------------

 * For fast preview you need XDVI.

[Excerpt from Peter Ganten's README.OS2 (missing in the package):
 ....
 -- Xdvi now understands drive letters and semicolons as path 
    separators
 -- Xdvi is now compiled with the SEARCH-SUBDIRECTORIES flag
 -- Xdvi will now call ghostscript to display postscript-pictures (see
    note below)
 -- MakeTeXPk.cmd will now look into your psfonts.map file and call
    gsftopk to display postscript fonts
 -- Xdvi will now use virtual fonts ... ]

 * For perfect preview of the printed
   output of LyX you need ghostview or gv (the latter needs xaw3d.dll 
   being renamed to xaw.dll) and a special version of Ghostscript for 
   X11. (The standard 'gsos2' lacks '-sDEVICE=x11' and will *not*
   work!). 

 * OS/2 ports (and necessary info) can be found using the links in:

http://www-set.gmd.de/~veit/os2/xf86ported.html,

   and Ghostscript in Michael Holzapfel's page:

http://www.ime.rwth-aachen.de/~michael/os2/ghostscript/index.html.
	
 * Configuration of EmTeX and XDVI to work poperly is a bit tricky,
   as they use different directory structures and syntax: 

    - You can export documents in tex format and preview later with 
      emTeX's tools.

    - Else you must unzip 'xdvi.zip' and 'xaw3d.zip' in %x11root%. Then
      correct the line 

	mapfile='d:\emtex\data\dvips\psfonts.map'

      in 'MakeTeXpk.cmd' so that it points to the psfonts.map file
      which came with dvips*.zip'. You will find this 'MakeTeXpk.cmd'
      in

	%x11root%\xfree86\bin

      SET XDVIFONTS to your upper TeX fonts directory 'foo':

	SET XDVIFONTS=x:/foo/*/%ddpi/%f.%p

      The asterisk means: search subdirectories and will be expanded,
      e.g. to 

x:/foo/pixel.lj/300dpi/fontname.pk

      For preview of Postscript fonts (Type 1) you need the
      corresponding virtual fonts und must use SET XDVIVFS like above:

SET XDVIVFS=D:/foo/vf;D:/foo/vf/adobe

     There is no possibility to search subdirectories here, so you have
     to list all directories with virtual fonts.

  * Gv needs to find gs.exe: You should rename gsos2.exe to gs.exe, 
    and move the executables and the dll to %PATH%. [According to the
    original documentation moving the dll to %LIBPATH% should work as 
    well. But on my system it doesn't.] Also you should add to 
    config.sys:

SET GS_LIB=x:/path_to_your_gs2dll.dll;*.ps_helper_files;type_1fonts
SET GS_FONTPATH=path_to_aditional_fonts_not_included_in_fontmap 

    For details please refer to the (often complicated) docs of the
    respective packages.


Here an example:
...
SET GS_LIB=D:/HYOTY/GSTOOLS/gs5.50;E:/PSFONTS;
SET GS_FONTPATH=D:/APPS/GSTOOLS/gs5.50/FONTS;E:/PSFONTS;

rem This is where EmTeX tree begins
SET EMTEXDIR=D:\EMTEX

rem  This is where Xdvi/dvips look for fonts (bitmap, virtual, type1
fonts, resp.)
SET XDVIFONTS=D:/texfonts/*/%ddpi/%f.%p
SET XDVIVFS=D:/texfonts/vf/%f.vf
SET T1FONTS=D:\PSFONTS;D:\XFREE86\LIB\X11\FONTS\TYPE1;
SET TEXCONFIG=D:/EMTEX/data/dvips

rem  TeX/LaTeX has to find its font metrics (*.tfm)
SET TEXTFM=D:\EMTEX\tfm!!

rem  TeX/LaTeX has to find its macros, etc. (*.sty; *.cls; *.tcp; etc.)
SET TEXINPUT=D:\EMTEX\TEXINPUT\LATEX2E!!;D:\EMTEX\TEXINPUT!!

rem  This is where dvipm/Xdvi looks for input data to preview
SET DVIDRVinput=D:\EMTEX\doc;D:\EMTEX\doc\latex;D:\EMTEX\doc\english;
SET DVIDRVGRAPH=D:\EMTEX\DOC
SET XDVIFIGS=D:/EMTEX/data/dvips;D:/HYOTY/GSTOOLS/gs5.50;E:/PSFONTS;
SET indexstyle=D:\emtex\idxstyle

rem Call mf386.exe to render missing bitmap fonts
SET MFJOBOPT=/3

SET indexstyle=D:\XFREE86\USR\emtex\idxstyle
SET EMTEXED=emacsclient +%1 %2

rem Where chktex stores its user configuration
SET chktexrc=%home%
.......

Do not copy it! You need to adapt it to your directory structure.


6) perl:
   ----

For LaTeX import (relyx.cmd) you need perl:
Check your local CPAN server for a recent OS/2 port or try:

	http://www.perl.org

Note:
----
If perl cannot find its modules and libraries it has a hardcoded
path chosen at compile time that does not match your configuration.
You can recompile with your directory structure or exchange the path
as follows (from man perlos2):

       PERLLIB_PREFIX

       Specific for EMX port. Should have the form

         path1;path2

       or

         path1 path2

       If the beginning of some prebuilt path matches path1, it
       is substituted with path2.

       Should be used if the perl library is moved from the
       default location in preference to PERL(5)LIB, since this
       would not leave wrong entries in @INC.  Say, if the
       compiled version of perl looks for @INC in f:/perllib/lib,
       and you want to install the library in h:/opt/gnu, do

         set PERLLIB_PREFIX=f:/perllib/lib;h:/opt/gnu"
On my system 'f:/perllib/lib' is hardcoded and has to be exchanged
for 'd:/bin/perllib/lib'. Also like many other programs ported from
UNIX (unfortunately this is also true for many XFree/2 programs) it 
uses a UNIX-like sh; you should give its path. 
I recommend sh.exe of pdksh.zip; other shells have problems.

Here an example of my config.sys:

rem Not default directory of perllib/lib (here:d:\bin) 
set PERLLIB_PREFIX=f:/perllib/lib;d:/bin/perllib/lib
rem Where sh.exe of pdksh.zip resides:
set PERL_SH_DIR=D:\bin

excerpt from perlos2:

      After you installed the components you needed and updated
       the Config.sys correspondingly, you need to hand-edit
       Config.pm. This file resides somewhere deep in the
       location you installed your perl library, find it out by

         perl -MConfig -le "print $INC{'Config.pm'}"

       You need to correct all the entries which look like file
       paths (they currently start with f:/).

       Warning

       The automatic and manual perl installation leave
       precompiled paths inside perl executables. While these
       paths are overwriteable (see the section on
       PERLLIB_PREFIX, the section on PERL_SH_DIR), one may get
       better results by binary editing of paths inside the
       executables/DLLs.

7) 'man' and 'gnugroff':
   --------------------

For reading unformatted manual pages in UNIX 'roff' format like the 
ones coming with LyX you need 'manxxx.zip' and 'gnugroff.zip', both 
available from www.leo.org.

Hint: 
----
gnugroff.zip (README.OS2 date: Feb 24th 1994) from Leo has a little 
bug concerning doc macros:

Please change file prefix and suffix in groff/tmac/mdoc directory to 
the following:

	doc-common
	doc-ditroff
	doc-nroff
	doc-syms

or adapt the content of

	groff\tmac\doc 

accordingly, so that it will find the distribution macros with 
non-standard names.

My proposed settings for man and groff are:

rem path to font directory
SET GROFF_FONT_PATH=D:/USR/local/lib/GROFF/FONT
rem path to tmac directory
SET GROFF_TMAC_PATH=D:/USR/local/lib/GROFF/TMAC
SET REFER=D:/XFREE86/USR/local/lib/GROFF/DICT/PAPERS/IND
rem system primary codepage
SET GROFF_TYPESETTER=cp850
rem where man finds it manual pages
SET MANPATH=D:/XFREE86/MAN;D:/XFREE86/usr/emx/doc/MAN
rem necessary for correct formatting of BSD man pages
set NROFF=GROFF -Tascii -mandoc



II. Installing a Binary Distribution:
    --------------------------------

0) Only for update: If you are upgrading from LyX v. 0.12.0,
   old documentation files in %HOME%/.lyx/doc/ and 
   %X11ROOT%/XFree86/lib/X11/lyx/doc should be removed before 
   unpacking (since they are read only). You might wish to make 
   a backup, if you want to keep old docs.

1) Unpack the distribution in the directory %X11ROOT% 

2) In config.sys SET LANG and LANGUAGE according to 
   your preferences and restart. 
     Beware: All programs supporting local
   languages will be affected, e.g.:

SET LANG=de_DE		rem german helpfiles will be used
SET LANGUAGE=de_DE	rem german menus and messages

Note1: For keyboard problems read the XFree documentation. Lyx 
	helpfiles also contain several hints.

Note2: German users should always use Layout; Document; Language:German
        and Encoding:latin1 to avoid problems with special characters. 
	This might apply to other languages, too.

Note3: As distributed, LyX expects to find
	its internationalization files in the directory
 %X11ROOT%/XFree86/lib/X11/locale
	its system configuration files in the directory
 %X11ROOT%/XFree86/lib/X11/lyx
	If you unpacked the distribution in directory c:\foo, add
	the environment variables LYX_LOCALEDIR and LYX_DIR_11x
	to config.sys to point to c:/foo/XFree86/lib/X11/locale and 
	c:/foo/XFree86/lib/X11/lyx as follows:
 SET LYX_LOCALEDIR=c:/foo/XFree86/lib/X11/locale 
 SET LYX_DIR_11x=c:/foo/XFree86/lib/X11/lyx
	Note that, if you do not have any interest in having LyX display
	its messages in other languages than english, you can safely 
	skip this step for LYX_LOCALEDIR.

3) At the root of the drive where your %HOME% resides, create a
   directory named tmp, if you haven't got one. LyX will need it, so 
   remember not to delete it later.

4) If updating make a backup of %HOME%\.lyx\lyxrc.defaults as it will 
   be changed.
   Read README and NEWS about updating and run 
   Options;Reconfigure as indicated.

5) Configure LyX for your system by executing
     lyx
   and choose Options->Reconfigure in the menu bar.
   Watch the messages there.

6) If you don't have %HOME%\.lyx\lyxrc now then move 
   %X11ROOT%\XFree86\lyxrc.example to %HOME%\.lyx\lyxrc. 
   Verify if LYX is able to find the programs mentioned 
   there and in %HOME%\.lyx\lyxrc.defaults. If not, 
   change name and path as required. Read LyX doc in

	Help->Customization 

  about customizing LyX for your needs. Read 

	Help->LatexConfiguration 

   to verify that all installed LaTeX packages which LyX can use 
   have been detected.
   Remember to repeat the check after any 'Reconfigure'!

7) Printer setup is difficult. The most simple solution is to print to a
   postscript file and the use gvpm for printing. If you have installed
   'printlp.exe' of 'gnugroff.zip' from 'ww.leo.org', you could try to 
   directly print to the local OS/2 spooler:

Excerpt from 'gnugroff.zip' README.OS2:

- New printlp and printdvi programs: Printlp captures all stdin input
  and spools it to "lpt1" (default) or the output device set in the
  environment variable LP_DEVICE. Printdvi captures all stdin input
  into a temporary file and calls the command "v" with the name as
  argument (v is the viewer in emTeX) or the command in the
  environment variable DVI_PRINT_COMMAND. If the command contains a
  %s, this will be replaced by the temporary file name.

I recommend to add to config.sys

	SET DVI_PRINT_COMMAND=VP

and to add to your lyxrc
	\print_spool_command "printdvi"

or printlp for postscript printer or if you already configured a 
postscript filter according to the LyX documentation. A different solution
to try is this one from Marcus von Cube (for xephem): Create an

	/* xprint.cmd */
	parse arg file
	file = translate( file, "\", "/" )
	'@print /d:lpt2 /b' file

(you may want to change "print /d:lpt2 /b" to "printdvi") or create a

	LPR-Installation:

If your %ETC%\INETD.LST contains the following line:
	printer tcp lpd
and inetd is running, you should be able to use lpr:
	lpr -s localhost -p lpt2 -b <filename>
It accepts "/" as path seperator.

This would mean adding 
	\print_spool_command "lpr"
	\print_spool_printerprefix "-s localhost -p lpt2 -b"


=======================================================================

	B. Compiling/Installing the source distribution with emx:
	   -----------------------------------------------------

++++to be written++++++

Some hints:

Run configure.cmd from top level lyx-xxx directory of the source distribution.
To create a smaller stripped version optimized for pentium on emx 0.9c type:
	configure.cmd --pentium-optimize

1,368,068 bytes (1.0.1 on emx 0.9c)

To create a smaller english-only version type:
	configure.cmd --disable-nls --pentium-optimize
and then type
cd src
x11make

I recommend to run 
	lib\configure.cmd --without-latex-config. 
The LaTeX configuration should better made when running LyX the first
time and can always be repeated with Menu: Options->Reconfigure. So I 
added --without-latex-config to the call at the end of top configure.cmd.

Run the following if you have tee.exe:
	configure.cmd 2>&1|tee errors.log
or
	configure.cmd --pentium-optimize 2>&1|tee errors.log

Read the logfile for any problems:
	cd.. & e errors.log

I recommend the following compilation settings:

set CC=gcc
set CONFIG_SHELL=d:/bin/sh.exe
set MAKE_SHELL=d:/bin/sh.exe
set EMX_FIX_CMD="emxbind -a \$@ ..."
SET C_INCLUDE_PATH=D:/XFREE86/INCLUDE/X11;d:/XFREE86/usr/emx/include
set CPLUS_INCLUDE_PATH=D:/XFREE86/INCLUDE/X11;d:/XFREE86/usr/emx/include/cpp;d:/XFREE86/usr/emx/include
set OBJC_INCLUDE_PATH=D:/XFREE86/INCLUDE/X11;d:/XFREE86/usr/emx/include
SET LIBRARY_PATH=D:/XFREE86/LIB/X11;d:/XFREE86/usr/emx/lib
set PROTODIR=d:/XFREE86/usr/emx/include/cpp/gen
set GCCLOAD=5
set GCCOPT=-pipe
set emxopt=-c
set MAKE=x11make.exe
set shell=/bin/sh

Now you can run

x11make

directly from toplevel source directory.


Note by Shigeru Miyata <miyata@kusm.kyoto-u.ac.jp>:
----------------------
Run configure.cmd rather than configure!  Notice it is not the
one in binary package, which is actually lib/configure.cmd, but
the one in the top directory of the source distribution.
It won't check the xpm version and other things BTW since I think
I can assume rather uniform installations on OS/2 (actually the
outdated error of the sh-script comes from an old header file,
not from the library, though.  Remove the incompatible header or
you will experience very weird, hard to track crashes).
Makefiles are not perfect, however:
  - You have to type make in src/ directory;
  - If you do not specify --disable-nls, you have to make libintl
    first;
  - make install/bindist won't work, the makefile in po/ directory
    not generated;
  - In order to link xforms statically, "-lforms" in LYX_LIBS flag
    must be modified manually to "-lforms_s -lulib -lsocket";
  - And probably more ;-(
Here is a statistic (exact size depends on libraries used,
codepage, etc.):
                          unstripped      stripped
emx09c                     10,735,882       1,634,308
emx09d                     15,938,707       2,899,972
emx09d (-fno-exceptions)   13,246,507       1,519,620
In LyX 1.2, g++-2.8 (emx09d) or later will be the definite
requirement.  (You cannot link 1.1 with emx09c, since the
executable size far exceeds 70M unstripped due to template codes,
for example.)
