-Build instructions for LIBTIFF - CodeWarrior (6.1):
-----------------------------------------------------
-
-Note: there is a bug in CW earlier than 6.1 which will generate
-16-bit offset link errors for any projects using libtiff; you must
-download the CodeWarrior 6.1 patch located at:
-
- ftp://ftp.metrowerks.com/pub/updates/metro-patches-61.hqx
-
-unpack the archive, insert the files and recompile the libraries
-using the AppleScript provided.
-
-
-1. Make sure that the directory containing these files is under
- the "contrib" directory of the tiff folder; otherwise, some
- access path preferences will need to be updated.
-
-2. The instructions below are for the 68k platform build.
- A similar script can be put together for the PPC version,
- or you can just directly convert the projects. Be sure to
- use the native libraries as well. NOTE: if anyone cooks
- up an equivalent script for PPC, send it to me and I'll include
- it with the rest of the package.
-
-3. Open the file Makefile.script with an AppleScript Editor
- and change the PATHNAME variable to point to your
- top-level TIFF directory
-
-4. Run the Script. It will do the following things:
-
- 4a. Prompt you for the current location of the CodeWarrior 68K
- program.
-
- 4b. Create the source file "tif_fax3sm.c":
-
- i) Build the project CW project mkg3states.cw. It will
- produce a small program called mkg3states. Only a
- 68k version is provided, since you only have to run
- this code once, and it only takes a few seconds.
-
- ii) Run the built mkg3states program:
-
- The program will temporarily take over ALL of the CPU, so
- don't panic. After a few seconds it will produce a file called
- "tif_fax3sm.c".
-
- 4c. Build the library project libtiff-68K.mw, producing library
- called libtiff-68K.
-
- 4d. Build program project tiffinfo.mw; it will produce a
- program called tiffinfo, which can dump the tiff tags of
- a named file. Passing in no arguments will dump a help file
- for the program. It is unix-flavored, but hey, it works.
-
-5 When the script finishes, you will have a usable libtiff-68K
- library, a passable "tiffinfo" program, and the projects used
- to build them. Note that to get tiffinfo to work I have put
- an include file in the project that redefines main(), and
- then have a mac_main.c program that calls ccommand() first
- and passes that to the actual main code. A real mac app,
- of course, would never use this stuff at all...
-
- . The tiffinfo.mw project may be used as a template to build
- most of the other libtiff tools, or your own code. When
- modifying a copy of the project, you will most likely need
- to update the "Access Paths" directory if it is moved out of
- the contrib folder.
-
-6. If you are going to create a project from scratch, be sure
- to set up the preferences with
-
- 4-byte ints
- 8-byte doubles
- Far Code/Far Data
- Large Linking model
-
- and everything should work fine. If the console-style error
- reports bother you, you can always override the error and
- warning mechanism with TIFFSetErrorHandler to do something
- more Mac-like.
