Otherwise, you can configure a build tree that is parallel to the source tree hierarchy but which contains only configured files and files created during the build procedure.

hyla% cd tiff-v3.4beta099
hyla% mkdir obj obj/mycpu
hyla% cd obj/mycpu
hyla% ../../configure

• building multiple targets from a single source tree
• building from a read-only source tree (e.g. if you receive the distribution on CD-ROM)

A second function of the configure script is to set the default configuration parameters for the software. Of particular note are the directories where the software is to be installed. By default the software is installed in the /usr/local hierarchy. To change this behaviour the appropriate parameters can be specified either:

• on the command line to configure,
• in a site-wide configuration file, or
• in a target-specific configuration file.

Site-wide configuration files are named config.site and are automatically searched for first in any directory specified on the command line to configure (using the -site option), or if that fails, in the directory in in which the configure script is located.

Target-specific configuration files are named config.local and are looked for first in the top-level configuration directory, or, if that fails, in the directory in which the configure script is located.

Configuration files are just shell scripts that define shell variables that control the configuration process. For example, the following file might be used on a BSDI system to configure the software for installation in the /usr/contrib area.

#
# Parameters suitable for BSDI 1.1
#
DIR_BIN="/usr/contrib/bin"		# directory for client apps
DIR_LIB="/usr/contrib/lib"		# directory for libraries
DIR_MAN="/usr/contrib/man"		# directory for manual pages

For a complete list of the possible configuration parameters look at the sample config.site file provided in the distribution; the section below describes some of the more important parameters.

Configuring Optional Packages/Support

DSO Support

The DSO support controls whether or not to configure the software to build a Dynamic Shared Object for the TIFF library. Use of DSOs can significantly reduce the disk space needed for users of the TIFF software. If DSOs are not used then the code is statically linked into each application that uses it. By default this support is configured only if the system appears to suport DSOs in a way that fits into the normal build scheme (auto). If DSO support is explicitly enabled and there is no support for using DSOs in the expected way then DSOs are not used.

JPEG Support

The JPEG package enables support for the handling of TIFF images with JPEG-encoded data. Support for JPEG-encoded data requires the Independent JPEG Group (IJG) libjpeg distribution; this software is available at ftp.uu.net:/graphics/jpeg/. If JPEG support is enabled the DIRS_LIBINC and DIR_JPEGLIB parameters should also be set (see below). By default JPEG support is not configured.

ZIP Support

The ZIP support enables support for the handling of TIFF images with deflate-encoded data. Support for deflate-encoded data requires the freely available zlib distribution written by Jean-loup Gailly and Mark Adler; this software is available at ftp.uu.net:/pub/archiving/zip/zlib/ (or try quest.jpl.nasa.gov:/beta/zlib/). If ZIP support is enabled the DIRS_LIBINC and DIR_GZLIB parameters should also be set (see below). By default this package is not configured.

Configuring TIFF Software v3.4beta015.

Reading site-wide parameters from ../tiff-v3.4beta015/config.site.
Reading local parameters from config.local.
Gosh, aren't you lucky to have a i386-unknown-bsdi1.1 system!

Using /usr/local/bin/gcc for a C compiler (set CC to override).
Looks like /usr/local/bin/gcc supports the -g option.
Using " -g" for C compiler options.

Note that an ANSI C compiler is required to build the software. If a C compiler requires options to enable ANSI C compilation, they can be specified with the ENVOPTS parameter.

Once a compiler is selected configure checks to see if the compiler accepts a -g option to enable the generation of debugging symbols, and if the compiler includes an ANSI C preprocessor.

Using /usr/ucb/make to configure the software.

Creating port.h. The port.h file is included by all the C code in the library (but not the tools). It includes definitions for functions and type definitions that are missing from system include files, #defines to enable or disable system-specific functionality, and other odds and ends.

Creating libtiff/port.h with necessary definitions.
... using LSB2MSB bit order for your i386 cpu
... using big-endian byte order for your i386 cpu
... configure use of mmap for memory-mapped files
... O_RDONLY is in <fcntl.h>
... using double for promoted floating point parameters
... enabling use of inline functions
Done creating libtiff/port.h.

Selecting emulated library functions. Certain library functions used by the tools are not present on all systems and can be emulated using other system functionality. configure checks for the presence of such functions and if they are missing, will configure emulation code from the port directory to use instead. Building the TIFF software on unsupported systems may require adding to the code to the port directory.

Checking system libraries for functionality to emulate.
Done checking system libraries.

Checking for Dynamic Shared Object (DSO) support.
Done checking for DSO support.

Selecting utility programs. configure locates various system utility programs that are used during installation of the software.

Selecting programs used during installation.
Looks like mv supports the -f option to force a move.
Looks like /bin/ln supports the -s option to create a symbolic link.
Done selecting programs.

Selecting default configuration parameters. The remainder of the work done by configure involves setting up configuration parameters that control the placement and setup of files during the installation procedure.

Selecting default TIFF configuration parameters.

Looks like manual pages go in /usr/contrib/man.
Looks like manual pages should be installed with bsd-nroff-gzip-0.gz.

TIFF configuration parameters are:

[ 1] Directory for tools:               /usr/contrib/bin
[ 2] Directory for libraries:           /usr/contrib/lib
[ 3] Directory for include files:       /usr/contrib/include
[ 4] Directory for manual pages:        /usr/contrib/man
[ 5] Manual page installation scheme:   bsd-nroff-gzip-0.gz

Are these ok [yes]? 

Once acceptable parameters are setup configure will generate all the files that depend on these parameters. Note that certain files may or may not be created based on the configuration of optional packages and/or the functions supported by target system.

Creating Makefile from ../tiff-v3.4beta015/Makefile.in
Creating libtiff/Makefile from ../tiff-v3.4beta015/libtiff/Makefile.in
Creating man/Makefile from ../tiff-v3.4beta015/man/Makefile.in
Creating tools/Makefile from ../tiff-v3.4beta015/tools/Makefile.in
Creating port/install.sh from ../tiff-v3.4beta015/port/install.sh.in
Done.

To add new support for building a shared library both these files must be updated. In the configure script search for the section where the autoconfiguration setting of the DSO parameter is handled and add a new case for the target system that sets the DSOSUF, DSOLD, DSOOPTS, and LIBCOPTS options as appropriate for the system. DSOSUF specifies the filename suffix used for the shared library (e.g. ``.so'' for Dynamic Shared Objects on most SVR4-based systems). DSOLD specifies the program to use to build the shared library from a compiled object file; typically ``${LD}'' though on some systems it is better to use the C compiler directly so system-dependent options and libraries are automatically supplied. DSOOPTS are options that must be specified to DSOLD when building the shared library. LIBCOPTS are options to pass to the C compiler when constructing a relocatable object file to include in a shared library; e.g. ``-K PIC'' on a Sun system. The DSO parameter must also be set to a unique label that identifies the target system and compilation tools. This label is used to select a target in libtiff/Makefile.in to do the actual work in building the shared library. Finally, to complete support for the shared library added the appropriate rules to libtiff/Makefile.in under the target specified in the configure script.

Configuration Parameters

AROPTS	The options passed to ar when creating an archive. Note that configure will automatically check to see if ar supports an s to create a symbol table instead of using ranlib.
DIR_BIN	The directory where client applications should be installed; by default this is /usr/local/bin.
DIR_GZLIB	The pathname of the directory containing the zlib library (when ZIP or PixarLog compression support is enabled); e.g. ``../src/zlib''.
DIR_JPEGLIB	The pathname of the directory containing the JPEG library (when JPEG support is enabled); e.g. ``/usr/local/lib''.
DIR_LIB	The directory to install libraries and DSO's; by default this is /usr/local/lib.
DIR_MAN	The top-most directory of the manual area where manual pages should be installed.
DIRS_LIBINC	A space-separated list of directories in which to search for include files when building the library and tools. If JPEG or ZIP support is configured this parameter should include the directories where the associated include files are located.
DIST_ALPHA	The alpha version number for the distribution; e.g. if this is version 3.4beta031 then the the major number is 31.
DIST_MAJOR	The major version number for the distribution; e.g. if this is version 3.4beta031 then the the major number is 3.
DIST_MINOR	The minor version number for the distribution; e.g. if this is version 3.4beta031 then the the major number is 4.
DSOSUF	When DSO's are built, the filename suffix for a DSO. If this is set to "a" then statically linked archives are used.
DSOSUF_VERSION	When DSO's are built, a version-specific filename suffix for a DSO. If this is set to something other than the value of DSO then the file libtiff.DSOSUF_VERSION will be installed and a link to it named libtiff.DSOSUF will automatically be created. (Note that this means that rule for building the target DSO must generate a file named libtiff.DSOSUF_VERSION.)
ENVOPTS	Options to pass to CC to force ANSI C compilation.
FILLORDER	The order of bits in a byte on the server machine; either LSB2MSB or MSB2LSB. This is normally selected according to the target system.
GCOPTS	Special options to pass the C compiler. If this parameter is set, then configure may append other options to this list.
INSTALL	The pathname of the install program to use. Note that this program must emulate the command line interface used by the IRIX install program.
LIBPORT	The pathname of the library that holds code to emulate missing system functionality. Normally this parameter is set by configure based on whether or not emulation code is required for the target.
LLDOPTS	Extra command line options passed to CC when linking an executable. This option is usually set only when DSO support is enabled (to force the executable to search for the TIFF DSO in non-standard locations in the filesystem.)
MACHDEPLIBS	Target-dependent libraries that should be used when linking tools. Note that if this parameter is specified configure will append to the list of libraries.
MANSCHEME	The scheme to use when preparing and installing manual pages. Schemes are constructed according to: <organization>-<formatting>-<compression>[-<suffix>] where: <organization> is either bsd for BSD-style section organization (e.g. file formats in section 5) or sysv for System V-style organization (e.g. file formats in section 4). <formatting> is either nroff to force installation of formatted materials (using nroff) or source to get the nroff source installed. <compression> is either the name of a program to compress the manual pages (gipz, compress, pack) or cat for uncompressed data. <suffix> is either the file suffix to convert installed pages to (e.g. 0.gz for gzip-compressed pages under BSD) or strip to force the normal ".4f" suffix to be converted to ".4" (or ".5" if using the BSD organization). If no -<suffix> is specified then filenames are not converted when they are installed.
PORTFUNCS	A list of non-standard functions that should be emulated. Normally this list is constructed by configure based on checks it does. If this parameter is set, configure will append to the specified list.
SETMAKE	If make does not automatically set $MAKE to the name of the make program to invoke for subdirectories, then configure will create an explicit definition. If this parameter is set, then it will be used instead. by default bin is used.

Building the Software under Windows 95/98/NT/2000 with MS VC++

C:\LIBTIFF\LIBTIFF> nmake /f makefile.vc
C:\LIBTIFF\LIBTIFF> cd ..\tools
C:\LIBTIFF\TOOLS> nmake /f makefile.vc

The makefile also builds a DLL (libtiff.dll) with an associated import library (libtiff_i.lib). Any builds using libtiff will need to include the LIBTIFF\LIBTIFF directory in the include path.

The libtiff\tools\makefile.vc should build .exe's for all the standard TIFF tool programs.

NOTE: The contents of the contrib/win32 directory should no longer be needed, and are kept in the distribution temporarily.

Building the Software under MS/DOS with the DJGPP v2 compiler

The directory contrib/dosdjgpp contains the files necessary to build the library and tools with the DJGPP v2 compiler under MSDOS.

All you have to do is copy the files in the directory into the respective directories and run make. If you want, you can use the conf.bat script to do that for you, make sure that the file is stored with MSDOS text EOL-convention (CR/LF), otherwise the command.com will not do anything.

Note that you probably will not be able to build the library with the v1.x versions of djgpp, due to two problems. First, the top makefile calls a sub-make for each directory and you are likely to run out of memory, since each recursive invocation of a djgpp v1.x program requires about 130k, to avoid that, you can enter the directories manually and call make (well, there are only two dirs). The 2nd problem is that djgpp 1.x doesn't call the coff2exe (stubify) program when creating an executable. This means that all programs compiled are not converted to exe and consequently are not available for calling directly. For the tools directory, you can just call coff2exe for each program after make finishes, but in the libtiff directory, a few programs are created during the make process that have to be called for make to continue (e.g. mkg3states). Make will probably report an error at each such stage. To fix that, either add a coff2exe call before each program is called or call coff2exe manually and rerun make (there 2-3 such programs).

Building the Software on a Macintosh with MPW

[From the file contrib/mac-mpw/README.]

This directory contains all of the utilities and makefile source to build the LIBTIFF library and tools from the MPW Shell. The file BUILD.mpw in this directory is an executable script which uses all of these files to create the MPW makefiles and run them.

The .make files are not MPW makefiles as such, but are when run through the "mactrans" program, which turns the ascii "%nn" metacharacters into the standard weird MPW make characters.

This translation trick is necessary to protect the files when they are put into unix tarfiles, which tend to mangle the special characters.

Building the Software on a Macintosh with CodeWarrior

[From the file contrib/mac-cw/README.] In this directory you will find a Makefile.script Applescript file, which should be run in order to build the libtiff code using MetroWerks CodeWarrior. Refer to the "metrowerks.note" instructions on building the library for 68k and PowerPC native code, as well as building some of the libtiff tools, which are rather unix-like, but at least give an example of how to link everything together.

Building the Software on a VMS System

1. Move the VMS specific files to their proper directories.

   $ SET DEFAULT DISK:[TIFF.CONTRIB.VMS]
   $ RENAME [.LIBTIFF]*.* [-.-.LIBTIFF]
   $ RENAME [.TOOLS]*.* [-.-.TOOLS]
   

2. Compile the library.

   $ SET DEFAULT DISK:[TIFF.LIBTIFF]
   $ @MAKEVMS
   

3. Compile the tools.

   $ SET DEFAULT DISK:[TIFF.TOOLS]
   $ @MAKEVMS
   

4. Define the programs.

   $ DEFINE TIFFSHR DISK:[TIFF.LIBTIFF]TIFFSHR
   $ FAX2PS    :==$DISK:[TIFF.TOOLS]FAX2PS
   $ FAX2TIFF  :==$DISK:[TIFF.TOOLS]FAX2TIFF
   $ GIF2TIFF  :==$DISK:[TIFF.TOOLS]GIF2TIFF
   $ PAL2RGB   :==$DISK:[TIFF.TOOLS]PAL2RGB
   $ PPM2TIFF  :==$DISK:[TIFF.TOOLS]PPM2TIFF
   $ RAS2TIFF  :==$DISK:[TIFF.TOOLS]RAS2TIFF
   $ RGB2YCBCR :==$DISK:[TIFF.TOOLS]RGB2YCBCR
   $ THUMBNAIL :==$DISK:[TIFF.TOOLS]THUMBNAIL
   $ TIFF2BW   :==$DISK:[TIFF.TOOLS]TIFF2BW
   $ TIFF2PS   :==$DISK:[TIFF.TOOLS]TIFF2PS
   $ TIFFCMP   :==$DISK:[TIFF.TOOLS]TIFFCMP
   $ TIFFCP    :==$DISK:[TIFF.TOOLS]TIFFCP
   $ TIFFDITHER:==$DISK:[TIFF.TOOLS]TIFFDITHER
   $ TIFFDUMP  :==$DISK:[TIFF.TOOLS]TIFFDUMP
   $ TIFFINFO  :==$DISK:[TIFF.TOOLS]TIFFINFO
   $ TIFFMEDIAN:==$DISK:[TIFF.TOOLS]TIFFMEDIAN
   $ TIFFSPLIT :==$DISK:[TIFF.TOOLS]TIFFSPLIT
   $ YCBCR     :==$DISK:[TIFF.TOOLS]YCBCR
   

This release has been tested on OpenVMS/VAX 5.5-2, using VAX C 3.2. A previous release was tested under OpenVMS/AXP ?.? using DEC C ?.?, it is believed that this release as well works on AXP. The code contains some GNU C specific things. This does *not* imply, however, that the VAX/GCC configuration has been tested, *it has not*.

The command procedures (MAKEVMS.COM) for building the library and tools, is believed to choose the correct options for the VAX and AXP cases automatically.

On the AXP, IEEE floating point is used by default. If you want VAX floating point, remove the /FLOAT=IEEE_FLOAT qualifier, and change HAVE_IEEEFP=1 to HAVE_IEEEFP=0 in the MAKEVMS.COM files in both the libtiff and tools directories.

Compiling your own program on a VMS system:

    $ CC/INCLUDE=DISK:[TIFF.LIBTIFF]

Linking your own program to the TIFF library on a VMS system:

1. Using the shareable TIFF library.

   $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS,SYS$INPUT:/OPTIONS
       SYS$SHARE:VAXCRTL/SHAREABLE
   

2. Using the TIFF object library.

   $ LINK MY_PROGRAM, -
       DISK:[TIFF.LIBTIFF]TIFF/LIBRARY/INCLUDE=(TIF_FAX3SM,TIF_CODEC), -
       SYS$INPUT:/OPTIONS
       SYS$SHARE:VAXCRTL/SHAREABLE
   

1. Using the shareable TIFF library.

   $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
   

2. Using the TIFF object library.

   $ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY
   

Method 2 gives somewhat longer link time and larger .EXE files, but does not require TIFFSHR to be defined. This method is recommended if you want to run your program on another machine, and for some reason don't want to have the library on that machine. If you plan to have more than one program (including the tools) on the machine, it is recommended that you copy the library to the other machine and use method 1.

Building the Software on an Acorn RISC OS system

This support was contributed by Peter Greenham. (peter@enlarion.demon.co.uk).

Installing LibTIFF:

LIBTIFF uses several files which have names longer than the normal RISC OS maximum of ten characters. This complicates matters. Maybe one day Acorn will address the problem and implement long filenames properly. Until then this gets messy, especially as I'm trying to do this with obeyfiles and not have to include binaries in this distribution.

First of all, ensure you have Truncate configured on (type *Configure Truncate On)

Although it is, of course, preferable to have long filenames, LIBTIFF can be installed with short filenames, and it will compile and link without problems. However, getting it there is more problematic. contrib.acorn.install is an installation obeyfile which will create a normal Acorn-style library from the source (ie: with c, h and o folders etc.), but needs the distribution library to have been unpacked into a location which is capable of supporting long filenames, even if only temporarily.

My recommendation, until Acorn address this problem properly, is to use Jason Tribbeck's LongFilenames, or any other working system that gives you long filenames, like a nearby NFS server for instance.

If you are using Longfilenames, even if only temporarily to install LIBTIFF, unpack the TAR into a RAMDisc which has been longfilenamed (ie: *addlongfs ram) and then install from there to the hard disk. Unfortunately Longfilenames seems a bit unhappy about copying a bunch of long-named files across the same filing system, but is happy going between systems. You'll need to create a ramdisk of about 2Mb.

Now you can run the installation script I've supplied (in contrib.acorn), which will automate the process of installing LIBTIFF as an Acorn-style library. The syntax is as follows:

install <source_dir> <dest_dir>

Install will then create <dest_dir> and put the library in there. For example, having used LongFilenames on the RAMDisk and unpacked the library into there, you can then type:

Obey RAM::RamDisc0.$.contrib.acorn.install RAM::RamDisc0.$ ADFS::4.$.LIBTIFF

It doesn't matter if the destination location can cope with long filenames or not. The filenames will be truncated if necessary (*Configure Truncate On if you get errors) and all will be well.

Compiling LibTIFF:

Once the LibTIFF folder has been created and the files put inside, making the library should be just a matter of running 'SetVars' to set the appropriate system variables, then running 'Makefile'.

OSLib

OSLib is a comprehensive API for RISC OS machines, written by Jonathan Coxhead of Acorn Computers (although OSLib is not an official Acorn product). Using the OSLib SWI veneers produces code which is more compact and more efficient than code written using _kernel_swi or _swi. The Acorn port of LibTIFF can take advantage of this if present. Edit the Makefile and go to the Static dependencies section. The first entry is:

# Static dependencies:
@.o.tif_acorn:   @.c.tif_acorn
	cc $(ccflags) -o @.o.tif_acorn @.c.tif_acorn 

Change the cc line to:

	cc $(ccflags) -DINCLUDE_OSLIB -o @.o.tif_acorn @.c.tif_acorn 

Remember, however, that OSLib is only recommended for efficiency's sake. It is not required.

Building the Software on Other Systems

The library requires two files that are generated on-the-fly. The file tif_fax3sm.c has the state tables for the Group 3 and Group 4 decoders. This file is generated by the mkg3states program on a UNIX system; for example,

cd libtiff
cc -o mkg3states mkg3states.c
rm -f tif_fax3sm.c
./mkg3states -c const tif_fax3sm.c

The second file required to build the library, version.h, contains the version information returned by the TIFFGetVersion routine. This file is built on most systems using the mkversion program and the contents of the VERSION and tiff.alpha files; for example,

cd libtiff
cc -o mkversion mkversion.c
rm -f version.h
./mkversion -v ../VERSION -a ../dist/tiff.alpha version.h

Otherwise, when building the library on a non-UNIX system be sure to consult the files tiffcomp.h and tiffconf.h. The former contains system compatibility definitions while the latter is provided so that the software configuration can be controlled on systems that do not support the make facility for building the software.

Systems without a 32-bit compiler may not be able to handle some of the codecs in the library; especially the Group 3 and 4 decoder. If you encounter problems try disabling support for a particular codec; consult the documentation.

Programs in the tools directory are written to assume an ANSI C compilation environment. There may be a few POSIX'isms as well. The code in the port directory is provided to emulate routines that may be missing on some systems. On UNIX systems the configure script automatically figures out which routines are not present on a system and enables the use of the equivalent emulation routines from the port directory. It may be necessary to manually do this work on a non-UNIX system.

Checking out the Software

Assuming you have working versions of tiffgt and tiffsv, you can just use them to view any of the sample images available for testing (see the section on obtaining the test images). Otherwise, you can do a cursory check of the library with the tiffcp and tiffcmp programs. For example,

tiffcp -lzw cramps.tif x.tif
tiffcmp cramps.tif x.tif

(tiffcmp should be silent if the files compare correctly).
