This is a port of Library lcms 2.3 to MSDOS/DJGPP.

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

        There are three DJGPP specific changes to the sources: first the one
        needed to resolved the conflict generated by hardcoded file names that
        are not 8.3 clean.  Only those files that do break the 8.3 file name
        restriction have been renamed.  Second, the new macro CMS_IS_DJGPP_ is
        defined for DJGPP and used to select sane defaults for the letters used
        as directory separators and the way absolute paths are detected.  Third,
        the DJGPP's repository versions of snprintf and vsnprintf have been
        included and are used, to make it possible to compile the sources with
        djdev203p2, that lacks both of these functions.
        As usual all files required to configure and compile the sources have
        been added to the /djgpp directory.
        Please note that there will be no support for the delphi, python
        and matlab utilities provided by the original package.
        Please also note that the sources may not be compiled if LFN support is
        not available.

        Please *read* the docs.  Especially /doc/tutorial.pdf and /doc/API.pdf



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 lcms23b.zip      or
          djtarx lcms23b.zip       or
          pkunzip -d lcms23b.zip



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

3.1.:   Create a temporary directory and copy the source package into the
        directory and just unzip it preserving the directory structure
        running *ONE* of the following commands:
          unzip32 lcms23s.zip      or
          djtarx lcms23s.zip       or
          pkunzip -d lcms23s.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  (or a later but NOT a prior version)
          gccNNNb.zip, gppNNN.zip, bnuNNNb.zip, makNNNb.zip, filNNNb.zip,
          shlNNNb.zip, txtNNNb.zip, txiNNNb.zip, grepNNNb.zip, sedNNNb.zip,
          gwkNNNb.zip, zlibNNNb.zip, tiffNNNb.zip, pngNNNb.zip, jpegNNNb.zip
          and jbigNNNb.zip.


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

        All this packages can be found in the v2gnu directory of ftp.delorie.com
        and any mirror.  NNN stands for the newest port versions available when
        this port was build but older may do the work as well.

3.3.:   The package has been configured for both DJGPP 2.03 and DJGPP 2.04.
        There is a separate build directory for DJGPP 2.03 and for DJGPP 2.04
        under the top srcdir (aka lcms2-2.3).  To build the binaries
        using the 2.03 version of DJGPP cd into _build.203; if you prefer to
        build the binaries using DJGPP 2.04 cd into _build.204.  If for some
        reason you want to reconfigure the package cd into the corresponding
        build directory and run the following commands:
          del config.cache
          make clean
          ..\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.

        config.bat, among other things, will start the configure script passing
        to it a couple of arguments.  You can control these argument passing the
        following command line arguments to config.bat:
          jpeg or no-jpeg, default jpeg.  Enable JPEG support.
          tiff or no-tiff, default tiff.  Enable TIFF support.
          zlib or no-zlib, default jpeg.  Enable ZLIB support.
        All other configure specific options are not set by config.bat so their
        values are left as they are.  If no arguments are passed to config.bat
        then the default values are used.


        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\gnu\lcms2-2.3\djgpp\config x:/src/gnu/lcms2-2.3

        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\gnu\lcms2-2.3\djgpp\config x:/src/gnu/lcms2-2.3

        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:
          make

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 lcms specific bug reports to the mailing list:
        <http://lists.sourceforge.net/lists/listinfo/lcms-user>.
        Send suggestions and bug reports concerning the DJGPP port to
        comp.os.msdos.djgpp or <djgpp@delorie.com>.


Enjoy.
