\cf0 As of version 6.13.0, BOINC does not support Macintosh PowerPC processors. As of 7.15.0, BOINC is built entirely for 64-bit Intel, including the BOINC libraries. As of 7.16.14, BOINC is built as Universal2 Binaries which can run on both 64-bit Intel and Apple Silicon (arm64) hardware. \
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 10.8.x or later 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\partightenfactor0

\f0\b \cf0 The above requirements apply not only to BOINC itself, but also to the WxWidgets, c-ares, cURL, openSSL,  freetype and ftgl libraries, as well as all project applications
\f1\b0 .  \

\f1\b0\fs24 \cf0 Apple provides the tools necessary to build BOINC on any Mac running OS 10.8.x or later.\
You get these tools, including the GCC or Apple LLVM compiler and system library header files, by installing the Xcode Tools package. \

\cf0 BOINC depends on seven third-party libraries: wxWidgets-3.1.5, c-ares-1.17.2, curl-7.79.1, openssl-3.0.0, freetype-2.11.0 and ftgl-2.1.3~rc5.  You can obtain the source files from the following URLs.  Clicking on the first URL of each pair will download the tar file.  The second URL will open the third party\'92s home web page.  On Mac OS X the tar file will usually be downloaded into the Downloads folder.  You will need to expand the tar files by double-clicking on them, which will create a folder and place the appropriate files into that folder. You will need to move these folders later.\

\f0\b \cf0 Note 1:
\f1\b0  Be sure to run the script using the

When the script finishes, it will display a warning about any libraries it was unable to build (for example, if you have not downloaded them.)  To make it easier to find the error messages, clear the Terminal display and run the script again without 
\f2 -clean
\f1 .\

\f0\b Note 3:
\f1\b0  
\f2\fs26 setupForBoinc.sh
\f1\fs24  runs

\f1\fs24  to build the wxWidgets library used by BOINC Manager. If you built the wxWidgets library with an earlier version of  
\f2\fs26 buildWxMac.sh
\f1\fs24 , then you must rebuild it with the 
\f2\fs26 buildWxMac.sh
\f1\fs24  included in the newer source tree. Otherwise, the BOINC Manager build will fail with linker (
\f2\fs26 ld
\f1\fs24 ) errors.\

\f0\b Note 4: 
\f1\b0 The \{path\} must not contain any space characters.\
\pard\pardeftab720\partightenfactor0

\f1\b0  To be compatible with OS 10.7 or earlier, the screensaver must be built with Garbage Collection (GC) supported (and without Automatic Reference Counting) , but Xcode versions later than 5.0.2 do not allow building with GC. To allow building with newer versions of Xcode while keeping backward compatibility to OS 10.7, the GIT repository includes the screensaver executable built with GC, while the Xcode project builds the screensaver with ARC (for newer versions of OS X.) The 
\f2\fs26 release_boinc.sh
\f1\fs24  script (described later in this document) adds both the GC and ARC builds of the screensaver to the installer; the installer code selects the correct screensaver for the target version of OS X at install time.\

\f1\b0 file.  You can either build directly in Xcode
\f0\b

\f2\fs26 \cf0 source BuildMacBOINC.sh [-dev] [-noclean] [-all] [-lib] [-client] [-libc] [-c++11] [-help]
\f1\fs24 \
\
The options for BuildMacBOINC.sh are:\
	-dev		build the development (debug) build. \
			default is deployment (release) build.\
\
	-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 six libraries: libboinc_api.a, libboinc_graphics_api.a, libboinc.a, libboinc_opencl.a, libboinc_zip.a, jpeglib.a\
\
	-client		build two targets: boinc client and command-line utility {\field{\*\fldinst{HYPERLINK "http://boinc.berkeley.edu/wiki/Boinccmd_tool"}}{\fldrslt 
\f2 \cf2 boinccmd}}\
			(also builds libboinc.a, since boinc_cmd requires it.)\
\
 	-libc		build using libc++ instead of libstdc++ (requires OS 10.7 or later)\
\
	-c++11	build using c++11 language dialect instead of default\
\
 Both -lib and -client may be specified to build eight targets (no BOINC Manager or screensaver.)\

\f0\b \cf0 Note 1:
\f1\b0  
\f0\b boinc.xcodeproj
\f1\b0  in the BOINC_dev/boinc/mac_build/ directory builds BOINC.  It can be used either with the 
\f2 BuildMacBOINC.sh
\f1  script or as a stand-alone project.  The 
\f5\i Development
\f1\i0  build configuration builds only the native architecture and is used for debugging.  The 
\f5\i Deployment
\f1\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.  \
\

\f0\b Note 2: 
\f1\b0 To perform a release build under Xcode 6 or later when not using the 
\f2 BuildMacBOINC.sh
\f1  script, select "Build for Profiling" from Xcode's Product menu.  To save disk space, do 
\f0\b not
\f1\b0  select "Archive."\
\

\f0\b Note 3: 
\f1\b0 Using the 
\f2\fs26 BuildMacBOINC.sh
\f1\fs24  script is generally easier than building directly in Xcode.  The script will place the built products in the directory 
\f2\fs26 BOINC_dev/boinc/mac_build/build/Deployment/
\f1\fs24  or 
\f2\fs26 BOINC_dev/boinc/mac_build/build/Development/
\f1\fs24  where they are easy to find.  Building directly in Xcode places the built products in a somewhat obscure location. To determine this location, control-click on 
\f5\i Products
\f1\i0  in Xcode's Project Navigator and select "Show in Finder."  \
\

\f0\b Note 4: 
\f1\b0 As of version 7.15.0, BOINC is always built using libc++. Project applications built for libstdc ++ with newer versions of Xcode will not link properly with BOINC libraries built for libc++. \
\

\f0\b Hint:
\f1\b0  You can install multiple versions of Xcode on the same Mac, either by putting them in different directories or by renaming Xcode.app of different versions.  You can then specify which version the 
\f2\fs26 BuildMacBOINC.sh
\f1\fs24  script should use by setting the 
\f2\fs26 DEVELOPER_DIR
\f1\fs24  environment variable using the 
\f2\fs26 env
\f1\fs24  command.  For example, if you have installed Xcode 6.2 in the Applications directory and renamed 
\f2\fs26 Xcode.app
\f1\fs24  to 
\f2\fs26 Xcode_6_2.app
\f1\fs24 , you can invoke the script with:\
\pard\pardeftab720\partightenfactor0

\f2\fs26 \cf0 env DEVELOPER_DIR=/Applications/Xcode_6_2.app/Contents/Developer sh BuildMacBOINC.sh
\f1\fs24 \

\cf0 \
The BOINC Xcode project has built-in scripts which create a text file with the path to the built products at either 
\f2\fs26 BOINC_dev/boinc/mac_build/Build_Deployment_Dir
\f1\fs24  or 
\f2\fs26 BOINC_dev/boinc/mac_build/Build_Development_Dir
\f1\fs24 .  These files are used by the 
\f2\fs26 release_boinc.sh
\f1\fs24  script, but you can also use them to access the built products directly as follows; open the file with TextEdit and copy the path, then enter command-shift-G in the Finder and paste the path into the Finder's  dialog.\
\
The standard release of BOINC version 7.15.0 and later builds only for Macintosh computers with 64-bit Intel processors.  The executables and libraries are built only for the x86_64 architecture.\

\cf0 \
In order to execute BOINC Manager, you must install it using BOINC Manager Installer. Otherwise, you will encounter an error prompting for proper installation.\
\
To build the Installer for the BOINC Manager, you must be logged in as an administrator.  If you are building BOINC version number x.y.z, type the following in Terminal, then enter your administrator password when prompted by the script:\
\
\pard\pardeftab720\partightenfactor0

\f2\fs26 \cf0 cd \{path\}/BOINC_dev/boinc/\

\cf0 Substitute the 3 parts of the BOINC version number for x y and z in the above.  For example, to build the installer for BOINC version 7.9.0, the command would be\
\pard\pardeftab720\partightenfactor0

\f2\fs26 \cf0 source \{path\}/BOINC_dev/boinc/mac_installer/release_boinc.sh 7 9 0\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\partightenfactor0

\f1\fs24 \cf0 This will create a directory "BOINC_Installer/New_Release_7_9_0" in the BOINC_dev directory, and the installer will be located in '
\f2\fs26 \{path\}/BOINC_dev/BOINC_Installer/New_Release_7_9_0/boinc_7.9.0_macOSX_x86_64
\f1\fs24 '.\
\
The installer script uses the deployment (release) build of BOINC; it won't work with a development (debug) build.\
You can find the current version number in the file

\f1 \cf0 Mac OS 10.8 introduces a security feature called Gatekeeper, whose default settings won't allow a user to run applications or installers downloaded from the Internet unless they are signed by a registered Apple Developer.  The 
\f2\fs26 release_boinc.sh
\f1\fs24  script looks for a file 
\f2\fs26 ~/BOINCCodeSignIdentities.txt
\f1\fs24  containing the name of a valid code signing identity stored in the user's Keychain.  If this is found, the script will automatically sign the BOINC installer and BOINC uninstaller using that identity.  For example, if your user name is John Smith, the first line of 
\f2\fs26 ~/BOINCCodeSignIdentities.txt
\f1\fs24  would be something like the following:
\f2\fs26 \
Developer ID Application: John Smith\
\
\pard\tx543\pardeftab543\pardirnatural\partightenfactor0

\f1\fs24 \cf7 \cb8 If you wish to also code sign the installer package, add a second line to 
\f2\fs26 ~/BOINCCodeSignIdentities.txt
\f1\fs24  with the installer code signing identity.  This \cf0 \cb1 would be something like the following:\
\pard\tx720\tx1440\tx2160\tx2880\tx3600\tx4320\tx5040\tx5760\tx6480\tx7200\tx7920\tx8640\partightenfactor0

\f1\fs24 \cf0 If there is no 
\f2\fs26 ~/BOINCCodeSignIdentities.txt
\f1\fs24  file, then the script will not sign the installer or uninstaller.  Code signing is not necessary if you won't be transferring the built software over the Internet.

\cf0 \CocoaLigature0 The LLDB 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 
\f5\i \CocoaLigature1 Development
\f1\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.  This also streamlines the development cycle by avoiding the need to run the installer for every change.  (To generate the development build under Xcode, choose "Build" from the product menu, or enter command-B on the keyboard.)\

\cf0 \CocoaLigature0 The BOINC Xcode project links the BOINC Manager with the non-debugging (Deployment) build of wxWidgets for the Deployment build configuration of the Manager, and with the debugging (Development) build of wxWidgets for the Development build configuration of the Manager.  You should use the Development build of the Manager and wxWidgets for debugging; this allows you to step into internal wxWidgets code. With the Development build, you can even put breakpoints in wxWidgets; this is most easily done after stepping into a function in wxWidgets source file containing the code where you wish to put the breakpoint.\

====================== Additional notes from \expnd0\expndtw0\kerning0
Robert Chalmers\kerning1\expnd0\expndtw0  ======================\
\
NOTE to building with XCode.\
The general instructions in the mac_build folder in the file HowToBuildBOINC_XCode.pdf should also note that if you want to build using XCode in it's GUI implementation - not command line - alone, you need to put all the downloaded libraries in the folder directly above the build folder. For EG:\
All of these external programs:\
\
wxWidgets-3.1.0\
curl-7.79.1:\
c-ares-1.17.2 (used by curl):\
openssl-3/0/0\
freetype-2.11.0 \
ftgl-2.1.3~rc5 \
\
Need to go into the top GitHub directory on your system and be unpacked there. Otherwise XCode  as the project is currently set up, will not find the libraries. They need to be unzipped there of course.\
\
/Users/<your name>/GitHub/\
\
So that when you build in XCode, they can be found in the existing setup, which looks for them in - for example - \
USER_HEADER_SEARCH_PATHS = ../../curl-7.79.1/include ../../openssl-3/0/0/include ../lib/**\
\
I found the existing how-to-build pdf slightly misleading. It could be that to command line build would benefit from having the external libraries in this folder directly above the 'boinc' folder.\
\
In my case I have \
/Users/Robert/Documents/GitHub\
    /boinc\
    /c-ares-1.17.2\
    /curl-7.79.1\
... and so on for the other required programs.\
\
Below the boinc folder there is of course the 'boinc/mac_build' folder.\
\
The result is\
