\cf0 Building BOINC for Macintosh OS X is complicated by the fact that Mac OS X is actually 2 different platforms:\
\pard\tx220\tx720\pardeftab720\li720\fi-720
\ls1\ilvl0\cf0 {\listtext	\'95	}
\b i686-apple-darwin
\b0 : 32-bit intel processors running OS 10.4.0 and above\
{\listtext	\'95	}
\b x86_64-apple-darwin
\b0 : 64-bit Intel processors running OS 10.5.0 and above\
\pard\pardeftab720\sa260
\cf0 As of version 6.13.0, BOINC does not support Macintosh PowerPC processors.\
Although BOINC supports 64-bit Intel project applications on Mac OS 10.5.0 and above, the only part of the BOINC client package built as a 64-bit executable is the screensaver coordinator for OS 10.6.x and later.  The BOINC libraries also include a 64-bit build so that they can be linked with 64-bit project applications.\
You need to take certain steps to ensure that you use only APIs that are available in all the OS versions BOINC supports for each architecture. The best way to accomplish this is to use a single development system running OS 10.7.x and cross-compile for the various platforms. The remainder of this document describes that process.\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\pardirnatural

\b \cf0 The above requirements apply not only to BOINC itself, but also to the WxWidgets, JPEG, c-ares, cURL and openSSL libraries, as well as all project applications
\b0 . Note: only the JPEG library must be built for  the x86_64 architecture, since it is used by the libboinc_graphics_api library.\

\cf0 Be sure to follow the directions in this document to ensure that these requirements are met.\

\cf0 Starting with version 6.1.0, the BOINC Client supports only Mac OS X 10.3.9 and later; support for OS 10.3.0 through 10.3.8 has been discontinued. This allows us to build the BOINC Client and Manager using only GCC 4.0, which offers a number of advantages.\
Starting with version 6.10.58, the BOINC Client supports only Mac OS X 10.4.0 and later. This allows it to be built with XCode 3.2 under OS 10.6.x, which does not support the Mac OS 10.3.9 SDK.\

\pard\pardeftab720\sa260

\f0\b0\fs24 \cf0 Apple provides the tools necessary to cross-compile for both BOINC Mac platforms on any Mac running OS 10.6.x or OS 10.7.x.\
You get these tools, including the GCC compilers and system library header files, by installing the Xcode Tools package. \
\pard\tx560\tx1120\tx1680\tx2240\tx2800\tx3360\tx3920\tx4480\tx5040\tx5600\tx6160\tx6720\pardirnatural

\b \cf0 Building BOINC now requires Xcode Tools version 3.2 or later but Xcode 4.2 or later is recommended. 
\b0  \
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640
\cf0 \
\pard\pardeftab720\sa260
\cf0 If you have the OS 10.6 installation DVD for your system, you can install Xcode Tools 3.2 at the time you install the OS, or you can install it later by opening the file 
\f1\fs26 Optional Installs/XCode Tools/XCodeTools.mpkg
\f0\fs24 .   \
You can download Xcode 3.2 or 4.2 from Apple's web site: {\field{\*\fldinst{HYPERLINK "http://developer.apple.com"}}{\fldrslt http://developer.apple.com}} (it is large: 1.1 GB).  You must be a member of the Apple Developer Connection to download the software, but you can join for free at: {\field{\*\fldinst{HYPERLINK "http://connect.apple.com/"}}{\fldrslt \cf2 http://connect.apple.com}}\cf2 .\cf0 \

\cf0 Source files are now archived using Subversion.  You can download svnX, a free GUI application for running Subversion from either\
	{\field{\*\fldinst{HYPERLINK "http://www.apple.com/downloads/macosx/development_tools/svnx.html"}}{\fldrslt http://www.apple.com/downloads/macosx/development_tools/svnx.html}}\

	{\field{\*\fldinst{HYPERLINK "http://www.lachoseinteractive.net/en/community/subversion/svnx/"}}{\fldrslt http://www.lachoseinteractive.net/en/community/subversion/svnx/}}\
\
You also need to install Subversion itself in the 
\f1\fs26 /usr/local/bin/
\f3  directory
\f0\fs24 .  By default, OS X and Xcode install it in 
\fs26 /
\f1 usr/bin/
\f0\fs24 .  To copy it into 
\f1\fs26 /usr/local/bin/
\f0 , enter the following in the Terminal utility application:\

\cf0 [1] Create a parent directory within which to work.  In this description , we will call it BOINC_dev, but you can name it anything you wish.\
\
[2] Put the following 3 directories inside the BOINC_dev folder (omit any you don't need):\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640

\cf0     wxMac-2.8.10\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640

\f0\fs24 \cf0 \
Important: do not change the names of any of these 3 directories.\
\
[3] Get the BOINC source tree from Subversion, and put it in the same BOINC_dev folder.  To do this, type the following in Terminal:\
\
\pard\pardeftab720

\f1\fs26 \cf0 cd \{path\}/BOINC_dev/
\f0\fs24 \

\f1\fs26 svn co http://boinc.berkeley.edu/svn/trunk/boinc
\f0\fs24   \
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640
\cf0 \
(You may change the name of the 
\f1\fs26 boinc
\f0\fs24  directory to anything you wish.)  Hint: if you have trouble getting this to work, try using 
\f1\fs26 https
\f0\fs24  instead of 
\f1\fs26 http
\f0\fs24 .\
\
The command above retrieves the source code from the HEAD (TRUNK) or development branch of the CVS repository.  For more information on getting the BOINC source code, see:\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640
{\field{\*\fldinst{HYPERLINK "http://boinc.berkeley.edu/trac/wiki/SourceCode"}}{\fldrslt 
\f1\fs26 \cf0 http://boinc.berkeley.edu/trac/wiki/SourceCode}}\
\
[4] Run the script to build the c-ares, curl, openssl and wxMac libraries as follows:\
\
\pard\pardeftab720

\f1\fs26 \cf0 cd \{path\}/BOINC_dev/boinc/mac_build/\
source setupForBoinc.sh -clean
\f0\fs24 \
\
If you don't wish to force a full rebuild of everything, omit the -clean argument.\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640
\cf0 \
Note: this script builds c-ares and curl first, followed by openssl, then jpeg and finally wxMac.  If you haven't downloaded wxMac because you aren't building the BOINC Manager, the script will build c-ares, curl, openssl and jpeg before quitting.  \
\
[5] Build BOINC as follows:\

\cf0 BOINC itself is built  using the 
\b boinc.xcodeproj 
\b0 file.  You can either build directly in Xcode
\b  
\b0 (more information below) or run the 
\b BuildMacBOINC.sh
\b0  script:\
\
\pard\pardeftab720

\f1\fs26 \cf0 cd \{path\}/BOINC_dev/boinc/mac_build/\
source BuildMacBOINC.sh
\f0\fs24 \

\f1\fs26 \cf0 source BuildMacBOINC.sh [-dev] [-noclean] [-all] [-lib] [-client] [-help]
\f0\fs24 \
\
The options for BuildMacBOINC.sh are:\
	-dev		build the development (debug) version (native architecture only). \
			default is deployment (release) version (universal binary: i386 and x86_64).\
\
	-noclean	don't do a "clean" of each target before building.\
			default is to clean all first.\
\
  The following arguments determine which targets to build\
	-all		build all targets (i.e. target "Build_All" -- this is the default)\
\
	-lib		build the five libraries: libboinc_api.a, libboinc_graphics_api.a, libboinc.a, libboinc_opencl.a, jpeglib.a\
\
	-client		build two targets: boinc client and command-line utility {\field{\*\fldinst{HYPERLINK "http://boinc.berkeley.edu/wiki/Boinccmd_tool"}}{\fldrslt boinc_cmd}}\
			(also builds libboinc.a, since boinc_cmd requires it.)\
\
 Both -lib and -client may be specified to build seven targets (no BOINC Manager or screensaver.)\

\b \cf0 Note:
\b0  You may find two Xcode projects in the BOINC_dev/boinc/mac_build/ directory: \
  \'95 
\b wxMac-BOINC.xcodeproj
\b0  was needed for building older versions of the wxMac library in conjunction with the older versions of the setupForBoinc.sh or buildWxMac.sh scripts.  It is not used for BOINC 5.9.2 or later.  \
  \'95 
\b boinc.xcodeproj
\b0  builds BOINC.  It can be used either with the BuildMacBOINC.sh script or as a stand-alone project.  The 
\i Development
\i0  build configuration builds only the native architecture and is used for debugging.  The 
\i Deployment
\i0  build configuration builds a universal binary and is suitable for release builds.  If there are any other build configurations, they should not be used as they are obsolete.  \
\

\b Note: 
\b0 To perform a release build under Xcode 4.2 when not using the BuildMacBOINC.sh script, select "Build for archiving" from Xcode's Product menu.  Do 
\b not
\b0  select "Archive."\
\
The standard release of BOINC version 6.13.0 and later builds only for Macintosh computers with Intel processors.  Most of the executables are built only for the i386 architecture.  The libraries and the screensaver are built as universal binaries containing builds for two architectures: i386 and x86_64.\
\

\b Important compatibility note
\b0 : Xcode 4.x comes with only two Mac SDKs: MacOSX10.6.sdk and MacOSX10.7.sdk.  The BOINC Xcode project uses MacOSX10.6.sdk so that it can build with either Xcode 4.x or Xcode 3.2.  However, a couple of the libraries in MacOSX10.6.sdk require OS 10.6 or later to run.  If you are building only to run on OS 10.6 or later, you don't need to do anything else.\
\
However, if you want to build BOINC so it will run on OS 10.4 and OS 10.5, you must either:\
 \'95 build with Xcode 3.2, or \
 \'95 build with Xcode 4.x after copying the MacOSX10.5.sdk from an older version of Xcode to your 
\f1\fs26 /Developer/SDKs/
\f0\fs24  folder.  The BOINC Xcode project will automatically detect the presence of that SDK and use the two older libraries needed for backward compatibility.\

\cf0 \CocoaLigature0 The GDB debugger can't attach to applications which are running as a different user or group so it ignores the S_ISUID and S_ISGID permission bits when launching an application.  To work around this, the BOINC 
\i \CocoaLigature1 Development
\i0 \CocoaLigature0  build does not use the special boinc_master or boinc_project users or groups, and so can be run under the debugger from Xcode.  \
\
The 
\i Development
\i0  build 
\i only
\i0  of the BOINC Manager allows you to change the ownership and permission settings of the BOINC Data and executables by entering an administrator user name and password.  This also streamlines the development cycle by avoiding the need to run the installer for every change.  (To generate the development build under Xcode 4.2, choose "Build" from the product menu, or enter command-B on the keyboard.)\
\
To restore the standard ownerships and permissions, run the installer.\

\cf0 \CocoaLigature0 The BOINC Xcode project normally links the BOINC Manager with the non-debugging (Deployment) build of wxWidgets, even for the Development build configuration of the Manager.  However, there may be times when you wish to link the Development build of the Manager to the Development build of wxWidgets for debugging, as when you want to step into internal wxWidgets code or put breakpoints in wxWidgets.\
