All the changes to incorporate libtiff and libjpeg into the xpdftools GS2 extension, to get libjpeg compiled up on 64 bit machines, and for both libs to be seen and used by xpdftools when this is built.

     458__________________________________________________________
     459
     4601. Issues building LIBJPEG on 64 bit machines and the patch
     461
     462I copied the LIBJPEG package from http://trac.greenstone.org/browser/other-projects/realistic-books/trunk/packages (also at http://trac.greenstone.org/browser/gs2-extensions/ocr/trunk/packages/cmdline).
     463
     464    * Configuring out of the box produced the following error:
     465       checking host system type... Invalid configuration `x86_64-unknown-linux-gnu': machine `x86_64-unknown' not recognized
     466
     467    * So that, as a consequence, when running make on the libjpeg package, make failed with the error:
     468       ./libtool --mode=compile gcc -I/home/greenstone/gs3-svn-26Mar2018/gs2build/ext/xpdf-tools/linux/include -fPIC  -I/home/greenstone/gs3-svn-26Mar2018/gs2build/ext/xpdf-tools/linux/include  -I. -c ./jcapimin.c
     469       make: ./libtool: Command not found
     470       make: *** [jcapimin.lo] Error 127
     471        Error encountered running *make * stage of ./CASCADE-MAKE/LIBJPEG.sh
     472
     473The same was true when I grabbed the libjpeg from sourceforge (https://sourceforge.net/projects/libjpeg/files/), which was also still version jpeg 6b from 2008.
     474
     475I found the following webpages discussing the above error messages:
     476- https://unix.stackexchange.com/questions/80479/how-to-work-with-libtool
     477- https://github.com/rwestlund/freesweep/issues/1
     478- https://ubuntuforums.org/showthread.php?t=1232714
     479- https://stackoverflow.com/questions/12828687/configure-fails-to-detect-proper-ld-on-a-64-bit-system-with-32-bit-userland
     480- SOLUTION: https://sourceforge.net/p/libjpeg/bugs/12/
     481
     482However, the error only strikes when configure is run with --enable-static.
     483
     484Note also that contrary to the above pages, running configure with the additional options
     485    --host=x86_64-linux-gnu --build=x86_64-linux-gnu --target=x86_64-linux-gnu --disable-shared --enable-static
     486did not help. Nor did adding the above flags get rid of configure attempting to work with host=x86_64-unknown(-unknown)-linux-gnu
     487
     488The SOLUTION, found when searching for the error message along with "enable-static", as it's the combination that is relevant, is described
     489at https://sourceforge.net/p/libjpeg/bugs/12/
     490
     491which was to patch up the config.sub filed included in the jpeg-6b tarball, to also cover x86_64-* machines:
     492        tahoe | i860 | x86_64-* | m32r | m68k | m68000 | m88k | ns32k | arc | arm \
     493
     494The above change is necessary because this libjpeg is outdated and has been superceded by other JPEG libraries, also discussed at https://sourceforge.net/p/libjpeg/bugs/12/
     495I'm not sure if those libraries are compatible with XpdfTools however, so I'm sticking with libjpeg as long as I can get it to build and be recognised by XpdfTools.
     496
     497The solution is once more to have a patch file: CASCADE-MAKE/LIBJPEG.sh replaces the config.sub with in the jpeg-6b package after this is untarred with packages/gs-libjpeg-config.sub, which contains the patch.
     498
     499
     5002. I followed the instructions at http://www.linuxfromscratch.org/blfs/view/6.3/general/libjpeg.html
     501to try to build libjpeg with --enable-static and --enable-shared to produce both libjpeg.a and libjpeg.so.
     502
     503However, nothing I try gets it to generate a libjpeg.so. It seems to always produce a libjpeg.a in xpdf-tools/linux/lib
     504regardless of whether CASCADE-MAKE/LIBJPEG.sh passes the --enable-static flag to the configure command or not, and regardless of whether --enable-shared is additionally or individually passed in.
     505
     506As a consequence, there's no  libjpeg.so file to set the -DJPEG_LIBRARY flag in XPDFTOOLS.sh to for when building xpdf-tools against dynamically linked libraries.
     507
     508I tried the various combinations with the lib jpeg-6b source tarballs from
     509- sourceforge, https://sourceforge.net/projects/libjpeg/files/, the latest tarball of this was from 2008
     510- http://www.linuxfromscratch.org/blfs/view/6.3/general/libjpeg.html, which was last updated in 2007
     511- http://trac.greenstone.org/browser/other-projects/realistic-books/trunk/packages/jpeg-6b.tar.gz, which was added to trac in 2009 but is probably the 2008 or 2007 version too.
     512
     513
     5143. Modifications for using TIFF and JPEG libraries when building Xpdf-Tools:
     515   
     516* CASCADE-MAKE.sh, replaced
     517    PACKAGES="CMAKE LIBZ LIBPNG FREETYPE XPDFTOOLS"
     518with
     519    PACKAGES="CMAKE LIBZ LIBTIFF LIBPNG LIBJPEG FREETYPE XPDFTOOLS"
     520
     521
     522* XPDFTOOLS.sh
     523If compiling statically make sure the CMake command contains the following changes:
     524        -DTIFF_INCLUDE_DIR=$prefix/include \        # <========== new
     525        -DJPEG_INCLUDE_DIR=$prefix/include \        # <========== new
     526        -DZLIB_LIBRARY=$prefix/lib/libz.a \
     527        -DTIFF_LIBRARY=$prefix/lib/libtiff.a \      # <========== new
     528        -DPNG_LIBRARY=$prefix/lib/libpng15.a \
     529        -DJPEG_LIBRARY=$prefix/lib/libjpeg.a \      # <========== new
     530        -DFREETYPE_LIBRARY=$prefix/lib/libfreetype.a \
     531        -DGSDLFLAG_STATIC="$static_flag" \
     532
     533
     534
     535The above flag names were discovered by deleting the untarred xpdf-4.00 folder.
     536Then in a fresh terminal, source devel.bash from xpdf-tools and re-run CASCADE-MAKE.sh without the above modifications:
     537
     538    -- Found FreeType (new-style includes): /home/greenstone/gs3-svn-26Mar2018/gs2build/ext/xpdf-tools/linux/lib/libfreetype.a

     545
     546
     547* packages/gs-CMakeLists.txt was modified again,
     548
     549    - this time to also pass:
     550        -ltiff and -ljpeg to all target_link_libraries() commands that run when GSDLFLAG_STATIC is set
     551    and
     552        ${TIFF_LIBRARY} and ${JPEG_LIBRARY} to all target_link_libraries() commands that run when GSDLFLAG_STATIC is not set

     556          include_directories("${JPEG_INCLUDE_DIR}")
     557          add_definitions("${JPEG_DEFINITIONS}")

     567          message(STATUS "@@@@@@@@@@@@@@@ NO TIFF_FOUND")
     568        endif ()
     569
     570    Note however that although gs-CMakeLists.txt now knows what the pluralised TIFF_INCLUDE_DIRS is (and TIFF_INCLUDE_DIR)
     571    as for PNG and ZLIB, gs-CMakeLists.txt does not have a value for the pluralised JPEG_INCLUDE_DIRS, only the
     572    JPEG_INCLUDE_DIRS set above. And both the CMAKE flags in XPDFTOOLS.sh for tiff and jpeg libs seem to have been setup
     573    in the same way now. Not sure where these automatically assigned variables come from in order to check up on them.
