Building the Filter Foundry plugin for Photoshop
------------------------------------------------

Notes on source code
--------------------
Source code, makefiles and IDE projects under GPL license are provided
for MPW (Classic & Carbon PowerPC targets), CodeWarrior 7
(Classic & Carbon PowerPC, Win32, 68K targets) and mingw32 (Win32 target).

A Photoshop SDK is required (available from Adobe Systems, http://www.adobe.com/).
The SDK was also distributed with Photoshop 6.0 and earlier.

The source has been built with SDK 6.0, CS2 and CS3 beta, but older
versions can be used.
(If building with SDK v4, edit 68k.r, carbon.r, classic.r, and PiMI_68k.r
to remove references to "PIResDefines.h", "PiPL.r" and "PiMI.r" and replace
with a single #include "PIGeneral.r"; also remove "fmtCanWriteTransparency"
from PiPL_common.r.)

Before attempting to build, you must edit the makefiles
("FilterFoundry.make" for MPW, "Makefile" for mingw32 or OS X), or change your
CodeWarrior project's access paths, to reflect the SDK's installed location.

In order to build the Carbon plugin with an SDK prior to version 7.0,
it is necessary to edit the SDK file :PhotoshopAPI:Resources:PIPL.r
as follows:
1. find the line "case CodePowerPC:"
2. duplicate the next 15 lines
3. in the copy only, change "case CodePowerPC:" to "case CodeCarbonPowerPC:"
   and change the 5 occurrences of "pwpc" to "ppcb"

Photoshop 7.0, CS and CS2 will load Carbon/PEF plugins built in this manner.
Only CodeWarrior and MPW can build these.

Photoshop CS2 also supports Mach-O format plugins. For details on how
these are built, see the Makefile (target "osx"). 

Photoshop CS3 supports "universal" (or "fat") plugins having native code
for both PowerPC and Intel architectures. The provided Makefile can build
a "universal" plugin if you have the CS3 "Beta" SDK (use target "fat").

Note that building Mach-O plugins requires Apple's Developer Tools
be installed (from the DVD that came with your Mac, or download from
http://developer.apple.com/ if you have an ADC login).


Mac notes
---------
The Mac build requires Apple's MoreFiles library, which can be obtained via
http://developer.apple.com/samplecode/Sample_Code/Files/MoreFiles.htm

Depending on how the source files were extracted, it may be necessary to set
the correct Mac file types before attempting to build. In MPW, this can
be done as follows. First set the current directory to the Filter Foundry
source directory, then:
	setfile -t TEXT Å.[chrly] Å.make Å.rc ::common:tt:Å ::common:adobeplugin:Å
This can also be necessary after regenerating y.tab.c and lex.yy.c.
These files are generated from the parser and lexical analyser definitions,
parser.y and lexer.l, by a UNIX Terminal (not MPW!) command such as:
	make y.tab.c lex.yy.c

If building with MPW, finished binaries are left in the "debug" directory;
these are good for testing and debugging, as they can be updated
and re-run without having to re-launch Photoshop.

The finished binary, which contains executables for Classic and Carbon,
is left in the "dist" directory.


Development systems
-------------------
While a CodeWarrior 7 project is provided, MPW and mingw32 are recommended 
as they produce much smaller executables.

Mingw32 (http://www.mingw.org/) can be hosted on virtually any UNIX or
Linux system, or under Windows.

MPW (http://developer.apple.com/tools/mpw-tools/) runs on PowerPC and
68K Macs under Mac OS 9 or earlier, or Classic under OS X.

To build in Windows with the OpenWatcom IDE, see the wpj subdirectory
and notes kindly provided by Peter Heckert.
