    27 This chapter contains step-by-step instructions on how to configure
       
    28 and build the TIFF software distribution. The software is most
       
    29 easily built on a UNIX system, but with a little bit of work it can
       
    30 easily be built and used on other non-UNIX platforms. <a name=

    33 <h2>Building on a UNIX System</h2>
       
    34 To build the software on a UNIX system you need to first run the
       
    35 configure shell script that is located in the top level of the
       
    36 source directory. This script probes the target system for
       
    37 necessary tools and functions and constructs a build environment in
       
    38 which the software may be compiled. Once configuration is done, you
       
    39 simply run <tt>make</tt> (or <tt>gmake</tt>) to build the software
       
    40 and then <tt>make install</tt> to do the installation; for example:
       
    41 <div style="margin-left: 2em">
       
    42 <pre>
       
    43 hyla% <b>cd tiff-v3.4beta099</b>
       
    44 hyla% <b>./configure</b>
       
    45     <i>...lots of messages...</i>
       
    46 hyla% <b>make</b>
       
    47     <i>...lots of messages...</i>
       
    48 hyla# <b>make install</b>
       
    49 </pre></div>
       
    50 Supplied makefiles are depend on GNU <tt>make</tt> utility, so you
       
    51 will need the one. Depending on your installation <b>make</b>
       
    52 command may invoke standard system <tt>make</tt> and <b>gmake</b>
       
    53 invoke GNU make. In this case you should use former. If you don't
       
    54 have <tt>make</tt> at all, but only <tt>gmake</tt>, you should
       
    55 export environment variable <tt>MAKE=gmake</tt> before
       
    56 <b>./configure</b>.
       
    57 <p>In general, the software is designed such that the following
       
    58 should be ``<i>make-able</i>'' in each directory:</p>
       
    59 <div style="margin-left: 2em">
       
    60 <pre>
       
    61 make [all]      build stuff
       
    62 make install    build&amp;install stuff
       
    63 make clean      remove .o files, executables and cruft
       
    64 make distclean  remove everything, that can be recreated
       
    65 </pre></div>
       
    66 Note that after running "<tt>make distclean</tt>" the
       
    67 <tt>configure</tt> script must be run again to create the Makefiles
       
    68 and other make-related files. <a name="BuildTrees" id=

    71 <h3>Build Trees</h3>
       
    72 There are two schemes for configuring and building the software. If
       
    73 you intend to build the software for only one target system, you
       
    74 can configure the software so that it is built in the same
       
    75 directories as the source code.
       
    76 <div style="margin-left: 2em">
       
    77 <pre>
       
    78 hyla% <b>cd tiff-v3.4beta099</b>
       
    79 hyla% <b>ls</b>
       
    80 COPYRIGHT       VERSION         config.sub      dist            man
       
    81 Makefile.in     config.guess    configure       html            port
       
    82 README          config.site     contrib         libtiff         tools
       
    83 hyla% <b>./configure</b>
       
    84 </pre></div>
       
    85 <p>Otherwise, you can configure a build tree that is parallel to
       
    86 the source tree hierarchy but which contains only configured files
       
    87 and files created during the build procedure.</p>
       
    88 <div style="margin-left: 2em">
       
    89 <pre>
       
    90 hyla% <b>cd tiff-v3.4beta099</b>
       
    91 hyla% <b>mkdir obj obj/mycpu</b>
       
    92 hyla% <b>cd obj/mycpu</b>
       
    93 hyla% <b>../../configure</b>
       
    94 </pre></div>
       
    95 This second scheme is useful for:
       
    96 <ul>
       
    97 <li>building multiple targets from a single source tree</li>
       
    98 <li>building from a read-only source tree (e.g. if you receive the
       
    99 distribution on CD-ROM)</li>
       
   100 </ul>
       
   101 <a name="ConfigOptions" id="ConfigOptions"></a>
       
   102 <hr width="65%" align="right">
       
   103 <h3>Configuration Options</h3>
       
   104 The configuration process is critical to the proper compilation,
       
   105 installation, and operation of the software. The configure script
       
   106 runs a series of tests to decide whether or not the target system
       
   107 supports required functionality and, if it does not, whether it can
       
   108 emulate or workaround the missing functions. This procedure is
       
   109 fairly complicated and, due to the nonstandard nature of most UNIX
       
   110 systems, prone to error. The first time that you configure the
       
   111 software for use you should check the output from the configure
       
   112 script and look for anything that does not make sense for your
       
   113 system.
       
   114 <p>A second function of the configure script is to set the default
       
   115 configuration parameters for the software. Of particular note are
       
   116 the directories where the software is to be installed. By default
       
   117 the software is installed in the <b>/usr/local</b> hierarchy. To
       
   118 change this behaviour the appropriate parameters can be specified
       
   119 on the command line to configure. Run <b>./configure --help</b> to
       
   120 get a list of possible options. Installation related options are
       
   121 shown below.</p>
       
   122 <pre>
       
   123 <tt>
       
   124 Installation directories:
       
   125   --prefix=PREFIX         install architecture-independent files in PREFIX
       
   126                           [/usr/local]
       
   127   --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
       
   128                           [PREFIX]
       
   129 
       
   130 By default, `make install' will install all the files in
       
   131 `/usr/local/bin', `/usr/local/lib' etc.  You can specify
       
   132 an installation prefix other than `/usr/local' using `--prefix',
       
   133 for instance `--prefix=$HOME'.

   159 <h3>Configuring Optional Packages/Support</h3>
       
   160 The TIFF software comes with several packages that are installed
       
   161 only as needed, or only if specifically configured at the time the
       
   162 configure script is run. Packages can be configured via the
       
   163 <b>configure</b> script commandline parameters.

   173 users of the TIFF software. If shared libarries are not used then
       
   174 the code is statically linked into each application that uses it.

   395 <h3>Shared Library Support</h3>
       
   396 It is desirable to make the TIFF library be a shared object on
       
   397 systems that have support for shared libraries. Unfortunately the
       
   398 rules to use to build a shared library vary between operating
       
   399 systems and even compilers. The distributed software includes
       
   400 support for building a shared version of the library on a number of
       
   401 different systems. This support is split between rules in the file
       
   402 <b>libtiff/Makefile.in</b> that construct the shared library and
       
   403 checks done by the <tt>configure</tt> script to verify that the
       
   404 expected rules are supported by compilation tools for the target
       
   405 system.
       
   406 <p>To add new support for building a shared library both these
       
   407 files must be updated. In the configure script search for the
       
   408 section where the autoconfiguration setting of the <tt>DSO</tt>
       
   409 parameter is handled and add a new case for the target system that
       
   410 sets the <tt>DSOSUF</tt>, <tt>DSOLD</tt>, <tt>DSOOPTS</tt>, and
       
   411 <tt>LIBCOPTS</tt> options as appropriate for the system.
       
   412 <tt>DSOSUF</tt> specifies the filename suffix used for the shared
       
   413 library (e.g. ``.so'' for Dynamic Shared Objects on most SVR4-based
       
   414 systems). <tt>DSOLD</tt> specifies the program to use to build the
       
   415 shared library from a compiled object file; typically ``${LD}''
       
   416 though on some systems it is better to use the C compiler directly
       
   417 so system-dependent options and libraries are automatically
       
   418 supplied. <tt>DSOOPTS</tt> are options that must be specified to
       
   419 <tt>DSOLD</tt> when building the shared library. <tt>LIBCOPTS</tt>
       
   420 are options to pass to the C compiler when constructing a
       
   421 relocatable object file to include in a shared library; e.g. ``-K
       
   422 PIC'' on a Sun system. The <tt>DSO</tt> parameter must also be set
       
   423 to a unique label that identifies the target system and compilation
       
   424 tools. This label is used to select a target in
       
   425 <b>libtiff/Makefile.in</b> to do the actual work in building the
       
   426 shared library. Finally, to complete support for the shared library
       
   427 added the appropriate rules to <b>libtiff/Makefile.in</b> under the
       
   428 target specified in the <tt>configure</tt> script. <a name="PC" id=

   445 </pre>
       
   446 <p>By default libtiff expects that a pre-built zlib and jpeg

   448 may edit libtiff\tiffconf.h using a text editor (e.g. notepad) and
       
   449 comment out the entries for JPEG_SUPPORT, PIXARLOG_SUPPORT, and
       
   450 ZIP_SUPPORT. Ignore the comment at the top of the file which says
       
   451 that it has no influence on the build, because the statement is not
       
   452 true for Windows. However, by taking this approach, libtiff will

   487 <p>The directory <b>contrib/dosdjgpp</b> contains the files
       
   488 necessary to build the library and tools with the DJGPP v2 compiler
       
   489 under MSDOS.</p>
       
   490 <p>All you have to do is copy the files in the directory into the
       
   491 respective directories and run make. If you want, you can use the
       
   492 <b>conf.bat</b> script to do that for you, make sure that the file
       
   493 is stored with MSDOS text EOL-convention (CR/LF), otherwise the
       
   494 <b>command.com</b> will not do anything.</p>
       
   495 <p>Note that you probably will not be able to build the library
       
   496 with the v1.x versions of djgpp, due to two problems. First, the
       
   497 top makefile calls a sub-make for each directory and you are likely
       
   498 to run out of memory, since each recursive invocation of a djgpp
       
   499 v1.x program requires about 130k, to avoid that, you can enter the
       
   500 directories manually and call make (well, there are only two dirs).
       
   501 The 2nd problem is that djgpp 1.x doesn't call the coff2exe
       
   502 (stubify) program when creating an executable. This means that all
       
   503 programs compiled are not converted to exe and consequently are not
       
   504 available for calling directly. For the tools directory, you can
       
   505 just call coff2exe for each program after make finishes, but in the
       
   506 libtiff directory, a few programs are created during the make
       
   507 process that have to be called for make to continue (e.g.
       
   508 mkg3states). Make will probably report an error at each such stage.
       
   509 To fix that, either add a coff2exe call before each program is
       
   510 called or call coff2exe manually and rerun make (there 2-3 such
       
   511 programs). <a name="MacMPW" id="MacMPW"></a></p>

   597 <p>This release has been tested on OpenVMS/VAX 5.5-2, using VAX C
       
   598 3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC
       
   599 C ?.?, it is believed that this release as well works on AXP. The
       
   600 code contains some GNU C specific things. This does *not* imply,
       
   601 however, that the VAX/GCC configuration has been tested, *it has
       
   602 not*.</p>
       
   603 <p>The command procedures (<tt>MAKEVMS.COM</tt>) for building the
       
   604 library and tools, is believed to choose the correct options for
       
   605 the VAX and AXP cases automatically.</p>
       
   606 <p>On the AXP, IEEE floating point is used by default. If you want
       
   607 VAX floating point, remove the <tt>/FLOAT=IEEE_FLOAT</tt>
       
   608 qualifier, and change <tt>HAVE_IEEEFP=1</tt> to
       
   609 <tt>HAVE_IEEEFP=0</tt> in the <tt>MAKEVMS.COM</tt> files in both
       
   610 the <b>libtiff</b> and <b>tools</b> directories.</p>
       
   611 <h3>Compiling your own program on a VMS system:</h3>
       
   612 When compiling a source file in which you <tt>"#include
       
   613 &lt;tiffio.h&gt;"</tt>, use the following command
       
   614 <pre>
       
   615     $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
       
   616 </pre>
       
   617 This ensures that the header file is found. On the AXP, also add
       
   618 <tt>/FLOAT=IEEE_FLOAT</tt> (if used when building the library).
       
   619 <h3>Linking your own program to the TIFF library on a VMS
       
   620 system:</h3>
       
   621 You can link to the library in two ways: Either using the shareable
       
   622 library, or using the object library. On the VAX these
       
   623 possibilities are:
       
   624 <ol>
       
   625 <li>Using the shareable TIFF library.
       
   626 <pre>
       
   627 $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
       
   628     SYS$SHARE:VAXCRTL/SHAREABLE
       
   629 </pre></li>
       
   630 <li>Using the TIFF object library.
       
   631 <pre>
       
   632 $ LINK MY_PROGRAM, -
       
   633     DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
       
   634     SYS$INPUT:/OPTIONS
       
   635     SYS$SHARE:VAXCRTL/SHAREABLE
       
   636 </pre></li>
       
   637 </ol>
       
   638 On AXP (and possibly also using DEC C on VAX) the corresponding
       
   639 commands are
       
   640 <ol>
       
   641 <li>Using the shareable TIFF library.
       
   642 <pre>
       
   643 $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
       
   644 </pre></li>
       
   645 <li>Using the TIFF object library.
       
   646 <pre>
       
   647 $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
       
   648 </pre></li>
       
   649 </ol>
       
   650 Method 1 uses the shortest link time and smallest <tt>.EXE</tt>
       
   651 files, but it requires that <tt>TIFFSHR</tt> is defined as above at
       
   652 link time and <strong>at run time</strong>. Using the compilation
       
   653 procedure above, the tools are linked in this way.
       
   654 <p>Method 2 gives somewhat longer link time and larger
       
   655 <tt>.EXE</tt> files, but does not require <tt>TIFFSHR</tt> to be
       
   656 defined. This method is recommended if you want to run your program
       
   657 on another machine, and for some reason don't want to have the
       
   658 library on that machine. If you plan to have more than one program
       
   659 (including the tools) on the machine, it is recommended that you
       
   660 copy the library to the other machine and use method 1. <a name=

   663 <h2>Building the Software on an Acorn RISC OS system</h2>
       
   664 The directory <b>contrib/acorn</b> contains support for compiling
       
   665 the library under Acorn C/C++ under Acorn's RISC OS 3.10 or above.
       
   666 Subsequent pathnames will use the Acorn format: The full-stop or
       
   667 period character is a pathname delimeter, and the slash character
       
   668 is not interpreted; the reverse position from Unix. Thus
       
   669 "libtiff/tif_acorn.c" becomes "libtiff.tif_acorn/c".
       
   670 <p>This support was contributed by Peter Greenham. (<a href=
       
   671 "mailto:peter@enlarion.demon.co.uk">peter@enlarion.demon.co.uk</a>).</p>
       
   672 <h3>Installing LibTIFF:</h3>
       
   673 <p>LIBTIFF uses several files which have names longer than the
       
   674 normal RISC OS maximum of ten characters. This complicates matters.
       
   675 Maybe one day Acorn will address the problem and implement long
       
   676 filenames properly. Until then this gets messy, especially as I'm
       
   677 trying to do this with obeyfiles and not have to include binaries
       
   678 in this distribution.</p>
       
   679 <p>First of all, ensure you have Truncate configured on (type
       
   680 <tt>*Configure Truncate On</tt>)</p>
       
   681 <p>Although it is, of course, preferable to have long filenames,
       
   682 LIBTIFF can be installed with short filenames, and it will compile
       
   683 and link without problems. However, <i>getting</i> it there is more
       
   684 problematic. <b>contrib.acorn.install</b> is an installation
       
   685 obeyfile which will create a normal Acorn-style library from the
       
   686 source (ie: with c, h and o folders etc.), but needs the
       
   687 distribution library to have been unpacked into a location which is
       
   688 capable of supporting long filenames, even if only temporarily.</p>
       
   689 <p>My recommendation, until Acorn address this problem properly, is
       
   690 to use Jason Tribbeck's <a href=
       
   691 "ftp://ftp.demon.co.uk/pub/mirrors/hensa/micros/arch/riscos/c/c020/longfiles.arc">
       
   692 LongFilenames</a>, or any other working system that gives you long
       
   693 filenames, like a nearby NFS server for instance.</p>
       
   694 <p>If you are using Longfilenames, even if only temporarily to
       
   695 install LIBTIFF, unpack the TAR into a RAMDisc which has been
       
   696 longfilenamed (ie: <tt>*addlongfs ram</tt>) and then install from
       
   697 there to the hard disk. Unfortunately Longfilenames seems a bit
       
   698 unhappy about copying a bunch of long-named files across the same
       
   699 filing system, but is happy going between systems. You'll need to
       
   700 create a ramdisk of about 2Mb.</p>
       
   701 <p>Now you can run the installation script I've supplied (in
       
   702 contrib.acorn), which will automate the process of installing
       
   703 LIBTIFF as an Acorn-style library. The syntax is as follows:</p>
       
   704 <p><tt>install &lt;source_dir&gt; &lt;dest_dir&gt;</tt></p>
       
   705 <p>Install will then create &lt;dest_dir&gt; and put the library in
       
   706 there. For example, having used LongFilenames on the RAMDisk and
       
   707 unpacked the library into there, you can then type:</p>
       
   708 <p><tt>Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$
       
   709 ADFS::4.$.LIBTIFF</tt></p>
       
   710 <p>It doesn't matter if the destination location can cope with long
       
   711 filenames or not. The filenames will be truncated if necessary
       
   712 (*Configure Truncate On if you get errors) and all will be
       
   713 well.</p>
       
   714 <h3>Compiling LibTIFF:</h3>
       
   715 <p>Once the LibTIFF folder has been created and the files put
       
   716 inside, making the library should be just a matter of running
       
   717 '<b>SetVars</b>' to set the appropriate system variables, then
       
   718 running '<b>Makefile</b>'.</p>
       
   719 <p><b>OSLib</b></p>
       
   720 <p><a href=
       
   721 "ftp://ftp.acorn.co.uk/pub/riscos/releases/oslib/oslib.arc">OSLib</a>
       
   722 is a comprehensive API for RISC OS machines, written by Jonathan
       
   723 Coxhead of Acorn Computers (although OSLib is not an official Acorn

   725 compact and more efficient than code written using _kernel_swi or
       
   726 _swi. The Acorn port of LibTIFF can take advantage of this if
       
   727 present. Edit the Makefile and go to the Static dependencies

   742 <h2>Building the Software on Other Systems</h2>
       
   743 This section contains information that might be useful if you are
       
   744 working on a non-UNIX system that is not directly supported. All
       
   745 library-related files described below are located in the
       
   746 <b>libtiff</b> directory.
       
   747 <p>The library requires two files that are generated
       
   748 <i>on-the-fly</i>. The file <b>tif_fax3sm.c</b> has the state
       
   749 tables for the Group 3 and Group 4 decoders. This file is generated
       
   750 by the <tt>mkg3states</tt> program on a UNIX system; for
       
   751 example,</p>
       
   752 <div style="margin-left: 2em">
       
   753 <pre>
       
   754 <tt>
       
   755 cd libtiff
       
   756 cc -o mkg3states mkg3states.c
       
   757 rm -f tif_fax3sm.c
       
   758 ./mkg3states -c const tif_fax3sm.c
       
   759 </tt>
       
   760 </pre></div>
       
   761 The <tt>-c</tt> option can be used to control whether or not the
       
   762 resutling tables are generated with a <tt>const</tt> declaration.
       
   763 The <tt>-s</tt> option can be used to specify a C storage class for
       
   764 the table declarations. The <tt>-b</tt> option can be used to force
       
   765 data values to be explicitly bracketed with ``{}'' (apparently
       
   766 needed for some MS-Windows compilers); otherwise the structures are
       
   767 emitted in as compact a format as possible. Consult the source code
       
   768 for this program if you have questions.
       
   769 <p>The second file required to build the library, <b>version.h</b>,
       
   770 contains the version information returned by the
       
   771 <tt>TIFFGetVersion</tt> routine. This file is built on most systems
       
   772 using the <tt>mkversion</tt> program and the contents of the
       
   773 <tt>VERSION</tt> and <tt>tiff.alpha</tt> files; for example,</p>
       
   774 <div style="margin-left: 2em">
       
   775 <pre>
       
   776 cd libtiff
       
   777 cc -o mkversion mkversion.c
       
   778 rm -f version.h
       
   779 ./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h
       
   780 </pre></div>
       
   781 <p>Otherwise, when building the library on a non-UNIX system be
       
   782 sure to consult the files <b>tiffcomp.h</b> and <b>tiffconf.h</b>.
       
   783 The former contains system compatibility definitions while the
       
   784 latter is provided so that the software configuration can be
       
   785 controlled on systems that do not support the make facility for
       
   786 building the software.</p>
       
   787 <p>Systems without a 32-bit compiler may not be able to handle some
       
   788 of the codecs in the library; especially the Group 3 and 4 decoder.
       
   789 If you encounter problems try disabling support for a particular
       
   790 codec; consult the <a href=
       
   791 "internals.html#Config">documentation</a>.</p>
       
   792 <p>Programs in the tools directory are written to assume an ANSI C
       
   793 compilation environment. There may be a few POSIX'isms as well. The
       
   794 code in the <b>port</b> directory is provided to emulate routines
       
   795 that may be missing on some systems. On UNIX systems the
       
   796 <tt>configure</tt> script automatically figures out which routines
       
   797 are not present on a system and enables the use of the equivalent
       
   798 emulation routines from the <b>port</b> directory. It may be
       
   799 necessary to manually do this work on a non-UNIX system. <a name=

   802 <h2>Checking out the Software</h2>
       
   803 <p>Assuming you have working versions of <tt>tiffgt</tt> and
       
   804 <tt>tiffsv</tt>, you can just use them to view any of the sample
       
   805 images available for testing (see the <a href="images.html">section
       
   806 on obtaining the test images</a>). Otherwise, you can do a cursory
       
   807 check of the library with the <tt>tiffcp</tt> and <tt>tiffcmp</tt>
       
   808 programs. For example,</p>
       
   809 <div style="margin-left: 2em">
       
   810 <pre>
       
   811 tiffcp -lzw cramps.tif x.tif
       
   812 tiffcmp cramps.tif x.tif
       
   813 </pre></div>
       
   814 <p>(<tt>tiffcmp</tt> should be silent if the files compare
       
   815 correctly). <a name="TOC" id="TOC"></a></p>
