This is a port of library lcms2 2.12 to MSDOS/DJGPP.



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

        This port has been configured to be build in the "_build" directory
        under the top srcdir.

        The port has been configured and compiled on WinXP SP3 and Win98SE.
        There is no guarantee that this may be possible with any other DOS-
        like OS.  Due to the use of long file names it will not be possible
        to configure and compile without LFN support.

        The port has been compiled using gcc346b and bnu2351b.

        There are two 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.
        Please note that there will be no support for the delphi, python and
        matlab utilities provided by the original package.  Please also note
        that it may be impossible to compile the sources if there is no LFN
        support.

        As usual, all djgpp specific files (config.bat, diffs, README files,
        etc.) are stored in the /djgpp directory.

        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 lcms212b.zip      or
          djtarx lcms212b.zip       or
          pkunzip -d lcms212b.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 lcms212s.zip      or
          djtarx lcms212s.zip       or
          pkunzip -d lcms212s.zip

3.2.:   To build the binaries you will need the following binary packages:
          djdev205.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,
          jbigNNNb.zip and xz-NNNa.zip


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

        NNN represents the latest version number of the binary packages.  All
        this packages can be found in the /v2tk directory of any
        ftp.delorie.com mirror.
        You will need bsh205bbr3.zip or later and *NOT* a prior version or
        the build will fail.  The same applies to djdev205.zip.

3.3.:   The package has been configured to be build in a separate build directory
        under the top srcdir (aka lcms2-2.12).  To build the binaries cd
        into /_build directory.  If for some reason you want to reconfigure the
        package cd into the 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 /_build
        directory 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 zlib.  Enable ZLIB support.
          fastfloat or no-fastfloat, default fastfloat.  Enable the build and
                                     install of the fast_float plugin, use only
                                     if GPL 3.0 is acceptable.
          threads or no-threads, default no-threads.  Enable POSIX threads API
                                                      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\contrib\lcms2-2.12\djgpp\config x:/src/contrib/lcms2-2.12

        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\lcms2-2.12\djgpp\config x:/src/contrib/lcms2-2.12

        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 directory where you have configured
        the sources the command:
          make

3.5.:   Now you can run the tests if you like. From the directory where you have
        configured the sources 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 lcms2 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.
