+wxWidgets for Mac OS X installation
+-----------------------------------
-On MacOS X, you can download Apple's free developer tools (gcc
-and associated headers and libraries, such as the Carbon API).
-You can then use configure in a similar way to compiling
-wxWidgets on Linux (or on Windows using MinGW or Cygwin). See
-'Apple Developer Tools' below for more details on using
-configure.
+wxWidgets can be compiled using Apple's Carbon or Cocoa libraries.
+Carbon is the older library, and Cocoa is the more modern library.
+In wxWidgets 2.9.x, Cocoa is the recommended library. While Carbon is still
+supported by Apple, little new work is being done in Carbon.
-Apple Developer Tools: command line
------------------------------------
+Most Mac OS X developers should start by downloading and installing Xcode
+from http://developer.apple.com. It is a free IDE from Apple that provides
+all of the tools you need for working with wxWidgets.
+
+After Xcode is installed, download either wxWidgets-{version}.tar.gz or
+wxMac-{version}.tar.gz and then double-click on it to unpack it to create
+a wxWidgets directory.
+
+Next use Terminal (under Applications, Utilities, Terminal) to access a command
+prompt. Use cd to change directories to your wxWidgets directory and execute
+one of the following sets of commands from the wxWidgets directory
+
+---------
+
+# Build the library for Cocoa (wxWidgets 2.9.0 and later)
+mkdir build-cocoa-debug
+cd build-cocoa-debug
+../configure --enable-unicode --enable-debug --disable-shared --with-osx_cocoa
+make;cd ..
+# Build the samples and demos
+cd build-cocoa-debug/samples; make;cd ../..
+cd build-cocoa-debug/demos; make;cd ../..
+
+---------
+
+# Build the library for Carbon
+mkdir build-carbon-debug
+cd build-carbon-debug
+../configure --enable-unicode --enable-debug --disable-shared
+make;cd ..
+# Build the samples and demos
+cd build-carbon-debug/samples;make;cd ../..
+cd build-carbon-debug/demos; make;cd ../..
+
+---------
+
+After the compilation completes, use Finder to run the samples and demos
+ Go to build-carbon-debug/samples to experiment with the Carbon samples.
+ Go to build-carbon-debug/demos to experiment with the Carbon demos.
+ Go to build-cocoa-debug/samples to experiment with the Cocoa samples.
+ Go to biuld-cocoa-debug/demos to experiment with the Cocoa demos.
+Double-click on the executables which have an icon showing three small squares.
+The source code for the samples is in wxWidgets/samples
+The source code for the demos is in wxWidgets/demos
+

+
+More information about building on Mac OS X is available in the wxWiki.
+Here are two useful links

+
+---------
-As in all Unix projects, you need to do something like this under MacOS X
-with the Apple Developer Tools installed:
+More advanced topics are covered below.
-1) cd into the base dir
-2) mkdir osx-build
-3) cd osx-build
-4) ../configure (add --with-osx_cocoa for the Cocoa port)
-5) make
+---------
If you want to install the library into the system directories you'll need
to do this as root. The accepted way of running commands as root is to
to create universal binaries.
If using the Apple command line tools, pass --enable-universal_binary when
-configuring wxWidgets. If you use wx-config --libs to link your application,
-he necessary linker flags will be added. When compiling your own files,
-you need to add -arch ppc -arch i386 to your CFLAGS.
+configuring wxWidgets. This will create the libraries for all the supported
+architectures, currently ppc, i386 and x86_64 when using Cocoa (Carbon isn't
+available in 64 bit builds). You may explicitly specify the architectures to
+use as a comma-separated list, e.g. --enable-universal_binary=i386,x86_64.
+
+Notice that if you use wx-config --libs to link your application, the -arch
+flags are not added automatically as it is possible to link e.g. x86_64-only
+program to a "fat" library containing other architectures. If you want to
+build a universal application, you need to add the necessary "-arch xxx" flags
+to your project or makefile separately.
As an alternative to using --enable-universal_binary, you can build for
each architecture separately and then use the lipo tool to glue the
projects / wxWidgets.git / blobdiff
