Alpine 1.10 for OS/2
(C) 2006-2008 The University of Washington.
OS/2 Port by Nicholas Sheppard (nps@zeta.org.au)


INTRODUCTION
============

This package contains all of the files that I needed to modify to get Alpine
compiling and running on OS/2.

I have tried to follow the Unix port as closely as possible, and the Windows
port for handling file names. There is a significant amount of OS/2-specific
code, however.


ON COMPILERS
============

These patches can be used to compile Alpine on OS/2 using gcc 3.2.1. Other
3.2.x versions of gcc may also work but I have not tried them.

The gcc 2.8.1 compiler distributed in the base EMX package cannot be used as
it does not support a number of the C library functions required by Alpine.

The gcc 3.3.x compilers distributed by Innotek cannot be used as they do not
support the terminal-handling routines used by Alpine.

I have not tried any non-gcc compilers.


WHAT YOU NEED
=============

  * the original Alpine source code, available from
    http://www.washington.edu/alpine

  * my OS/2 patches, available from
    http://www.zeta.org.au/~nps/software/alpine/en/index.html

  * gcc 3.2.1, available from Hobbes and OS/2 Site

  * Some form of the make utility. I used GNU Make; others may or may
    not work.

  * ncurses for OS/2, available from the ./os2/dev/util directory on your
    favourites Hobbes mirror.

  * OpenSSL for OS/2, available from http://www.openssl.org
    (also see http://silk.apana.org.au/apache/building-ssl.html).
    Alpine's makefile assumes that you have compiled OpenSSL as a pair
    of DLLs.

  * an /etc/passwd emulation library; my own Pwd/2 is available from
    http://www.zeta.org.au/~nps/software/pwd2/en/index.html

  * GNU patch, available from the ./os2/dev/util directory on your
    favourite Hobbes mirror.


BUILDING ALPINE
===============

1. Unpack the original sources and change to the alpine-1.10 directory:

   bzip2 -d alpine-1.10.tar.bz2 [or gzip]
   tar xvf alpine-1.10.tar
   cd alpine-1.10

2. Delete the old OS/2-dependent files from the IMAP toolkit:

   attrib -r imap\* /s
   del imap\src\osdep\os2\*

3. Unpack and apply the new OS/2 patches:

   unzip -o alpine-1.10-os2-src.zip
   gpatch -p 1 < alpine-1.10-os2.patch

   Make sure you are using GNU patch, not OS/2's patch.

4. Open Makefile.os2 check that the macros in the "Configuration" section
   match your set-up. You should not need to modify anything below the
   "config" target.

5. Run "make -f Makefile.os2" to compile the executables. They will be stored
   in the "bin" sub-directory.

6. Run "make -f Makefile.os2 dist" to copy all of the support files into the
   "bin" sub-directory. This sub-directory will now look like the binary
   distribution and can be configured by following the instructions in
   README.OS2

Other useful targets are:

   make -f Makefile.os2 package  -- create the binary distribution packages
   make -f Makefile.os2 clean    -- remove all of the temporary files
