   1 wxWidgets for Mac OS X installation
   2 -----------------------------------
   3
   4 wxWidgets can be compiled using Apple's Carbon or Cocoa libraries.
   5 Carbon is the older library, and Cocoa is the more modern library.
   6
   7 In wxWidgets 2.9.x, Cocoa is the recommended library.  While Carbon is still
   8 supported by Apple, little new work is being done in Carbon.
   9
  10 Most Mac OS X developers should start by downloading and installing Xcode
  11 from http://developer.apple.com.  It is a free IDE from Apple that provides
  12 all of the tools you need for working with wxWidgets.
  13
  14 After Xcode is installed, download either wxWidgets-{version}.tar.gz or
  15 wxMac-{version}.tar.gz and then double-click on it to unpack it to create
  16 a wxWidgets directory.
  17
  18 Next use Terminal (under Applications, Utilities, Terminal) to access a command
  19 prompt.  Use cd to change directories to your wxWidgets directory and execute
  20 one of the following sets of commands from the wxWidgets directory
  21
  22 ---------
  23
  24 # Build the library for Cocoa (wxWidgets 2.9.0 and later)
  25 mkdir build-cocoa-debug
  26 cd build-cocoa-debug
  27 ../configure --with-osx_cocoa --enable-debug
  28 make
  29 # Build the samples and demos
  30 cd samples; make;cd ..
  31 cd demos;   make;cd ..
  32
  33 ---------
  34
  35 # Build the library for Carbon
  36 mkdir build-carbon-debug
  37 cd build-carbon-debug
  38 ../configure --with-osx_carbon --enable-debug
  39 make
  40 # Build the samples and demos
  41 cd samples;make;cd ..
  42 cd demos;  make;cd ..
  43
  44 ---------
  45
  46 After the compilation completes, use Finder to run the samples and demos
  47   Go to build-carbon-debug/samples to experiment with the Carbon samples.
  48   Go to build-carbon-debug/demos to experiment with the Carbon demos.
  49   Go to build-cocoa-debug/samples to experiment with the Cocoa samples.
  50   Go to biuld-cocoa-debug/demos to experiment with the Cocoa demos.
  51 Double-click on the executables which have an icon showing three small squares.
  52 The source code for the samples is in wxWidgets/samples
  53 The source code for the demos is in wxWidgets/demos

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

  64 More advanced topics are covered below.

  66 ---------
  67
  68 If you want to install the library into the system directories you'll need
  69 to do this as root.  The accepted way of running commands as root is to
  70 use the built-in sudo mechanism.  First of all, you must be using an
  71 account marked as a "Computer Administrator".  Then
  72
  73 6) sudo make install
  74 7) type <YOUR OWN PASSWORD>
  75
  76 Note that while using this method is okay for development, it is not
  77 recommended that you require endusers to install wxWidgets into their
  78 system directories in order to use your program.  One way to avoid this
  79 is to configure wxWidgets with --disable-shared.  Another way to avoid
  80 it is to make a framework for wxWidgets.  Making frameworks is beyond
  81 the scope of this document.
  82
  83 Note:
  84 It is rarely desirable to install non-Apple software into system directories.
  85 By configuring the library with --disable-shared and using the full path
  86 to wx-config with the --in-place option you can avoid installing the library.
  87

  89 Apple Developer Tools: Xcode
  90 ----------------------------
  91
  92 You can use the project in src/wxWindows.xcodeproj to build wxWidgets,
  93 and there is a sample project supplied with the minimal sample.
  94
  95 Notice that the command line build above builds not just the library itself but
  96 also wxrc tool which doesn't have its own Xcode project. If you need this tool,
  97 the simplest possibility is to build it from the command line after installing
  98 the libraries using commands like this:
  99
 100 $ cd utils/wxrc
 101 $ g++ -o wxrc wxrc.cpp `wx-config --cxxflags --libs base,xml`
 102
 103 Creating universal binaries
 104 ---------------------------
 105
 106 The Xcode projects for the wxWidgets library and minimal project are set up
 107 to create universal binaries.
 108
 109 If using the Apple command line tools, pass --enable-universal_binary when
 110 configuring wxWidgets. This will create the libraries for all the supported
 111 architectures, currently ppc, i386 and x86_64 when using Cocoa (Carbon isn't
 112 available in 64 bit builds). You may explicitly specify the architectures to
 113 use as a comma-separated list, e.g. --enable-universal_binary=i386,x86_64.
 114
 115 Notice that if you use wx-config --libs to link your application, the -arch
 116 flags are not added automatically as it is possible to link e.g. x86_64-only
 117 program to a "fat" library containing other architectures. If you want to
 118 build a universal application, you need to add the necessary "-arch xxx" flags
 119 to your project or makefile separately.
 120
 121 As an alternative to using --enable-universal_binary, you can build for
 122 each architecture separately and then use the lipo tool to glue the
 123 binaries together. Assuming building on a PPC system:
 124
 125 1. First build in the usual way to get the PPC library.
 126
 127 2. Then, build for Intel, in a different folder. This time use:
 128
 129 export CFLAGS="-g -isysroot /Developer/SDKs/MacOSX10.4u.sdk -arch i386"
 130 export LDFLAGS="-syslibroot,/Developer/SDKs/MacOSX10.4u.sdk"
 131
 132 ./configure --disable-dependency-tracking --enable-static=yes --enable-shared=no \
 133   --target=i386-apple-darwin8 --host=powerpc-apple-darwin8 --build=i386-apple-darwin8
 134
 135 You will need to reverse the powerpc and i386 parameters everywhere to build PPC on an Intel
 136 machine.
 137
 138 3. Use lipo to glue the binaries together.
