This is a port of library TIFF 3.9.4 to MSDOS/DJGPP.

1.:     DJGPP specific changes.
	=======================

        This port requires the use of the CVS version of snprintf.  Other minor
        djgpp specific changes are documented in the diffs file.  Apart from
        these changes only the usual configuration files have been added,
        especialy sed scripts to fix the libtool files (ltmain and ltconfig).
        They are located in the /djgpp directory.  As for all binaries and
        libraries that handle images of any kind, it should be noticed that
        files (streams) are *always* openend in binary mode with all the well
        known implications on a DOS/WINDOWS OS if the stream is connected to
        STDIN and/or STDOUT when these are still connected to the console.

	To use and compile from sources this library, you will have to install
	the zlib, png, jpeg and jbig libraries.

	  
	Please *READ* the docs.


2.:     Installing the binary package.
	==============================

2.1.:   Copy the binary distribution into the top DJGPP installation directory,
	just unzip it preserving the directory structure running *ONE* of the
	following commands:
          unzip32 tiff394b.zip      or
          djtarx tiff394b.zip       or
          pkunzip -d tiff394b.zip



3.:     Building the binaries from sources.
	===================================

3.1.:   Create a temporary directory and copy the source package into the
	directory.  If you download the source distribution from one of the
	DJGPP sites, just unzip it preserving the directory structure
	running *ONE* of the following commands:
          unzip32 tiff394s.zip      or
          djtarx tiff394s.zip       or
          pkunzip -d tiff394s.zip

3.2.:   To build the binaries you will need the following binary packages:
          djdev203.zip (or a later but NOT a prior version)
          bsh205bbr3.zip  (NOT an other version)
          gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
          shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, sedNNNb.zip,
          and m4NNN.zip

        If you want to run the check you will need also:
          difNNNb.zip

        NNN represents the latest version number of the binary packages.
        All these packages can be found in the /v2gnu directory of any
        ftp.delorie.com mirror.
        You will need bsh205bbr3.zip and *NOT* an other version or the build
        will fail.  The same applies to djdev203.zip.

3.3.:   If for some reason you want to reconfigure the package cd into the top
	srcdir (libtiff3.9-4) and run the following commands:
	  del djgpp\config.cache
	  make distclean
	  djgpp\config

	Please note that you *MUST* delete the config.cache file in the djgpp
	subdir or you will not really reconfigure the sources because the
	configuration informations will be read from the cache file instead
	of being newly computed.
	To build the programs in a directory other than where the sources are,
	you must add the parameter that specifies the source directory,
	e.g:
	  x:\src\contrib\libtiff3.9-4\djgpp\config x:/src/contrib/libtiff3.9-4

	Lets assume you want to build the binaries in a directory placed on a
	different drive (z:\build in this case) from where the sources are,
	then you will run the following commands:
	  z:
	  md \build
	  cd \build
	  x:\src\contrib\libtiff3.9-4\djgpp\config x:/src/contrib/libtiff3.9-4

	The order of the options and the srcdir option does not matter.  You
	*MUST* use forward slashes to specify the source directory.

	The batch file will set same environment variables, make MSDOS specific
	modifications to the Makefile.in's and supply all other needed options
	to the configure script.

3.4.:   To compile the package run from the top srcdir the command:
	  sh ./djgpp/makeTIFF.sh

3.5.:   Now you can run the tests if you like.  From the top srcdir run the
	command:
	  make check

	No test should fail.

3.6.:   To install the binaries, header, library, catalogs, and info docs
	run the following command from the top srcdir:
	  make install

	This will install the products into your DJGPP installation tree given
	by the default prefix "/dev/env/DJDIR".  If you prefer to install them
	into some other directory you will have to set prefix to the appropiate
	value:
	  make install prefix=z:/some/other/place



	Send library TIFF  specific bug reports to <tiff@lists.maptools.org>.
	Send suggestions and bug reports concerning the DJGPP port to
	comp.os.msdos.djgpp or <djgpp@delorie.com>.


Enjoy.
