This builds GRASS as a Mac OS X application, more or less.\
\
The startup wrapper is a simple AppleScript that fires up a custom grass.sh (instead of the standard grass6x) and quits, leaving grass.sh running in a new Terminal window.  The custom grass.sh takes care of some default and required environment settings (so the user doesn't have to fiddle with .bash_profile), makes sure X11 in running, then starts init.sh.\

Building GRASS as a Mac OS X application is pretty much the same as for a unix build (see the "INSTALL" document for details).  For an application, just add this option to configure:\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\f0\fs24 \cf0 \
With this option, the 
\f1\fs20 --prefix
\f0\fs24  specified is the path where GRASS.app will be installed.  The default GRASS prefix is 
\f1\fs20 /usr/local
\f0\fs24 , but for a Mac OS X application it should be 
\f1\fs20 /Applications
\f0\fs24 .  It is not possible to have alternative default prefixes in configure, so you must set 
\f1\fs20 --prefix=/Applications
\f0\fs24  yourself for configure.\
\
The makefile tries to figure out the location of the GDAL programs, from the configured GDAL libs.  This is set in grass.sh, and if it doesn't correctly figure it out (some GRASS commands fail to find needed GDAL commands), set GDAL_BIN before running make:\
\

The GRASS build system is very friendly to a Universal build (unlike libtool-based builds).  
\i This applies to a standard unix build as well as the app build.
\i0   First, a couple things to check:\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\b \cf0 \'95 The Universal SDK
\b0 .  
\i This is only needed when building on OSX 10.4 PPC - the Intel system is all Universal, and so is 10.5 for both architectures (though you may still want to use an SDK).
\i0   Using the SDK forces GCC to use an alternate root for everything, so if a dependency is not in the SDK (/usr/local is NOT in the SDK), you will get configure, compile and link errors about missing stuff.  To fix this, create symlinks in the SDK to where you have your extra dependencies.  The SDKs in Leopard are mostly taken care of.\
\
For example, /usr/local:\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\f1\fs20 \cf0 sudo ln -s /usr/local /Developer/SDKs/MacOSX10.4u.sdk/usr/local\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\f0\fs24 \cf0 \
For Leopard, there may be problems locating 
\f1\fs20 bin
\f0\fs24  programs.  Add the following:\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\f0\fs24 \cf0 \
If there are subfolders involved that are not already in the SDK, add them first.  Say you have some libraries in /Users/Shared/unix (I put my static libraries there):\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\b \cf0 \'95 Universal Dependencies
\b0 .  Make sure all your extra dependencies are Universal.\
\

\b \'95\'a0 Tiger+
\b0 .  This will NOT work on anything less than OSX 10.4.\
\
If those check OK, here's what to do.  Simply add the universal flags to all compile and link commands.  This is done by setting CFLAGS, CXXFLAGS and LDFLAGS before configuring the build.  The basic flags are:\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\f0\fs24 \cf0 \
If you are building on OSX 10.4 PPC only, also add this:\

\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\li180\fi-180\ql\qnatural\pardirnatural

\cf0 \ul Optimization\ulnone \
\
By default, GRASS configures with debugging symbols turned on (the "-g" flag), and level 2 optimization ("-O2").  If you don't want debugging on (it greatly increases the binary size) or want to use a different optimization, just add an optimization flag to the above CFLAGS and CXXFLAGS exports.  Specifying an optimization disables debugging.  Some common optimizations are (see the gcc man page for complete details):\
\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\f1\fs20 \cf0 -O2
\f0\fs24 	most optimizations, a common default\

\f1\fs20 -O3
\f0\fs24 	high\

\f1\fs20 -Os
\f0\fs24 	optimize for speed, also keep the binary size small (the Apple standard)\
\
If you want debugging with a different optimization flag, use one of the above optimization flags plus "
\f1\fs20 -g
\f0\fs24 ".\
\
Remember to separate all flags with spaces.\

That's a long line, but you have to be very explicit in the GRASS configure (and yes, the UnixImageIO framework is used multiple times).\
\
If you don't have the PROJ framework programs folder in your shell PATH, it will fail to find nad2bin.  To correct this set NAD2BIN before running configure:\
\

Sometimes, for mysterious reasons so far, the automatic check for X11 fails.  Depending on various conditions, you may immediately notice this because configure stops.  If X11 isn't found automatically, add this to the configure line 
\i (this applies to both the unix build and app build)

The linker in Leopard's GCC from Xcode 3.0 has a bit of a problem with some libraries, notably X11's libGL.  When trying to link libGL (for example), it spits back an error:\

Xcode 3.1 does not have this problem.  In other words, make sure to install the latest Xcode.\
\
\'95 64bits\
\
Almost all of GRASS can be built 64bits. Use the above universal flags section and set the arch's to "
\f1\fs20 ppc64
\f0\fs24 " for PPC processors (I believe all are inherently 64bits), and "
\f1\fs20 x86_64
\f0\fs24 " for Intel processors (ie Core 2 Duo, but not Core Duo).  You don't need to build universal, but can have only one arch flag if desired. The SDK flag is not needed.\
\
The wxPython parts(ie vdigit) cannot be built 64bits.  This is due to Carbon not being 64bit, which wx depends on.  Because gui/wxpython shares CXXFLAGS with the rest of GRASS, vdigit will fail unless the makefile it patched.\

After running make, 
\f1\fs20 make bindist
\f0\fs24  will assemble an installer package.  This will have the name "GRASS-[version].pkg" and will be found in the macosx folder in the GRASS source.  On Tiger, there 
\b will be
\b0  some 
\b non-fatal errors
\b0  - 
\i this is normal
\i0  and the installer package is still generated correctly.\
\
The installer takes care of binary installation, and creating the /Library/GRASS support folder and Help Viewer link.\
\
This installer currently does NOT do any verification of installed dependencies or system version.\

\cf0 \ul Bundling Libraries and Programs\

With the installer package build, additional dependent libraries and programs can be bundled with the application package to make a more portable and easily installed GRASS application.  See 
\f1\fs20 macosx/pkg/bundle.make
\f0\fs24  for details.\
\
GRASS uses 
\f1\fs20 DYLD_LIBRARY_PATH
\f0\fs24 , which is set to the application's lib folder, so it will find any libraries that are there that are not found in their expected locations.  It also adds the application bin folder to the 
\f1\fs20 PATH
\f0\fs24 , so helper programs installed there will be found.\
\
There is NO need to bundle 
\i everything
\i0 .  Bundling readily available libraries and programs installed in standard locations is not necessary.  Some things you might want to bundle include:\
\
- GPSBabel (CLI)\
- NetPBM programs (just what is used in GRASS)\
- ffmpeg libraries\
- Postgres library (libpq)\
\
Things to leave out:\
\
- applications that duplicate the above items (ie GPSBabel.app)\
- /Library/Frameworks stuff\

The applescript startup and grass.sh can be customized if desired, ie for a more complex startup that might give the user a dialog for startup options.  They just provide the basic core to build upon.\

Help files are linked into the OSX help system.  Independent of what browser you choose to open help files (
\f1\fs20 GRASS_HTML_BROWSER
\f0\fs24 ), you can open Help Viewer from almost any application's Help menu (it's best to use Mac Help from the Finder Help menu), and GRASS Help will be available in the Library menu.\
\
Since they are linked to the help system, if GRASS.app is moved or renamed, the link will be broken.  This may change in the future.\

\b\fs28 \cf0 Addon Modules\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\ql\qnatural\pardirnatural

\b0\fs24 \cf0 \
Do not use GEM (at this time) for building and installing addon modules.  It installs in the app dir, which is not the right thing to do in OSX.  It is still installed - the gem executable is in 
\f1\fs20 Contents/MacOS
\f0\fs24  - and may work, but it's untested.\
\
GRASS.app is setup to find addon modules in 
\f1\fs20 /Library/GRASS/$VERSION/Modules
\f0\fs24  and 
\f1\fs20 ~/Library/GRASS/$VERSION/Modules
\f0\fs24 .  The version is the Major.minor version of GRASS.  /Library modules are globally available to all users, but require admin privileges to install.  Home/Library modules are only available to the user that installed them.\
\
When GRASS is started, grass.sh adds these to the 
\f1\fs20 GRASS_ADDON_PATH
\f0\fs24 , 
\f1\fs20 GRASS_ADDON_ETC
\f0\fs24  and 
\f1\fs20 DYLD_LIBRARY_PATH
\f0\fs24 .  It also rebuilds the html help index, and GUI menu file.\
\
GRASS_ADDON_ETC is fairly new, and many addon modules may not make use of it yet.  Instead of accessing it's etc/ support files from $GISBASE/etc, the function G_find_etc("file") should be used to locate the file wherever it may be in any of the folders listed in GRASS_ADDON_ETC.  $GISBASE/etc is searched last and does not need to be included in GRASS_ADDON_ETC.\
\
Help indexes and GUI menus for both global and user modules are maintained in the user's Library/GRASS folder, so the user doesn't need admin privs to write to the global folder.\
\
The 
\b modbuild
\b0  target creates a GEM-like build skeleton that can be used to build modules from the Terminal.  It does not require any special setup of the module source.  It does not install, or rather I haven't tested that, but it uses standard GRASS make files so it should be able to.\

The simplest way to install Tcl/Tk Aqua is to download {\field{\*\fldinst{HYPERLINK "http://www.activestate.com/Products/activetcl/"}}{\fldrslt ActiveTcl}} from ActiveState.  This will give you a universal 32bit Tcl/Tk Aqua.  \ul Make sure to run the

A universal GPSBabel is also possible to build without too much fuss.  First, you need the GPSBabel source from {\field{\*\fldinst{HYPERLINK "http://www.gpsbabel.org/"}}{\fldrslt www.gpsbabel.org}}.  If you need support for USB GPS units, get the libusb 0.1 source from {\field{\*\fldinst{HYPERLINK "http://libusb.sourceforge.net/"}}{\fldrslt libusb.sourceforge.net}}.  It needs X11 for libexpat.  Do not get the new libusb 1.0 beta, that has a completely API and GPSBabel doesn't support it yet, as far as I can make out.\
\
For libusb, unzip the source and cd to the source folder in a Terminal.  Then:\

Libusb will be installed in /usr/local.  GPSBabel uses the static library, so the shared libusb is not needed, and you might have problems building libusb as shared.\

NetPBM is not too hard to build, it's just weird.  These instructions use my UnixImageIO framework for the tiff, jpeg, png and jasper libraries.\

FFMPEG is constantly changing, there is no released version, it's all in SVN.  These instructions are work on the SVN revision listed above, so if a current SVN version doesn't work, try checking out that revision.  You need 
\b SVN
\b0  installed to download the FFMPEG source.\
\
This will build a basic FFMPEG as static libraries for use with GRASS.  No extra formats are included, such as mp3lame and xvid.  Note that by default debug symbols are included, so you will get a large binary out of this.  Stripping the libraries doesn't seem to work.\
\
First, create a folder for your ffmpeg source and cd into it.  Now:\

It's a two-step build, 1 for each architecture, and I'm being explicit for each arch.  The -fno-common extra cflag is needed or there will be link errors in GRASS, and OSX Intel has MMX issues, so it is disabled.  For the Intel build:\

If you want to remove the debug symbols, edit config.mak at this point and remove "-g" from OPTFLAGS.\
