Installation and use of the TIFF library and tools under VMS
It is assumed that you have unpacked the tar file into a VMS directory
tree, in this text called DISK:[TIFF].
Installation:
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
$ TIFFCP :==$DISK:[TIFF.TOOLS]TIFFCP
$ TIFFCMP :==$DISK:[TIFF.TOOLS]TIFFCMP
$ TIFFINFO :==$DISK:[TIFF.TOOLS]TIFFINFO
$ TIFFDUMP :==$DISK:[TIFF.TOOLS]TIFFDUMP
$ TIFF2PS :==$DISK:[TIFF.TOOLS]TIFF2PS
$ TIFFDITHER:==$DISK:[TIFF.TOOLS]TIFFDITHER
$ TIFF2BW :==$DISK:[TIFF.TOOLS]TIFF2BW
$ TIFFMEDIAN:==$DISK:[TIFF.TOOLS]TIFFMEDIAN
$ TIFFSPLIT :==$DISK:[TIFF.TOOLS]TIFFSPLIT
$ 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
You will want to add these lines to your LOGIN.COM file, after changing
the name of the directory that you have used on your machine.
Compiling your own program
When compiling a source file in which you "#include <tiffio.h>", use the
following command
$ CC/INCLUDE=DISK:[TIFF.LIBTIFF]
This ensures that the header file is found.
Linking your own program to the TIFF library
You can link to a library in two ways: Either using the shareable
library, or using the object library. This gives the following
possibilities
1) Using the shareable TIFF library
$ LINK MY_PROGRAM,SYS$INPUT:/OPTIONS
DISK:[TIFF.LIBTIFF]TIFF/OPTIONS
SYS$SHARE:VAXCRTL/SHAREABLE
2) Using the TIFF object library and shareable C run time library
$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY,SYS$INPUT:/OPTIONS
SYS$SHARE:VAXCRTL/SHAREABLE
3) Using the TIFF object library and object C run time library
$ LINK MY_PROGRAM,DISK:[TIFF.LIBTIFF]TIFF/LIBRARY,-
SYS$LIBRARY:VAXCRTL/LIBRARY
(You may think of a fourth possibility, but that is not possible)
Method 1 uses the shortest link time and smallest .EXE files, but it
requires that TIFFSHR is defined as above at link time and
*at*run*time*. Using the compilation procedure above, the tools are
linked in this way.
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 rcommended that
you copy the library to the other machine and use method 1.
Method 3 gives even longer link times and .EXE files, it not recommended
unless you are going to use your program on a machine without a
shareable C library.
