# Script for building Macintosh BOINC Manager, Core Client and libraries
# by Charlie Fenton 3/27/08
# with thanks to Reinhard Prix for his assistance
#
# Updated for OS 10.7 Lion and XCode 4.2 on 10/19/11
# Updated 7/9/12 for Xcode 4.3 and later which are not at a fixed address
# Updated 2/7/14 to also build libboinc_zip.a
# Updated 11/28/15 to build ScreenSaver with ARC under Xcode 6 or later
# Updated 2/15/16 to allow optional use of libc++ and C++11 dialect
# Updated 3/11/16 to remove obsolete targets MakeAppIcon_h & WaitPermissions
# Updated 3/13/16 to add -target and -setting optional arguments
# Updated 10/17/17 to fix bug when -all argument is implied but not explicitly passed
# Updated 10/19/17 Special handling of screensaver build is no longer needed
# Updated 10/14/18 for Xcode 10 (use this script only with BOINC 7.15 or later)
# Updated 3/31/21 To eliminate redundant -c++11 arg since C++11 build is now standard
# Updated 5/19/21 for compatibility with zsh
# Updated 7/12/22 result is moved out of eval string to get correct status on CI if build fails
# Updated 2/14/23 refactoring made to build zip apps (-zipapps), uc2 samples (-uc2) and vboxwrapper (-vboxwrapper)
# Updated 3/12/23 Don't unnecessary rebuild libraries for uc2, zip apps or vboxwrapper
#
## This script requires OS 10.8 or later
#
## If you drag-install Xcode 4.3 or later, you must have opened Xcode
## and clicked the Install button on the dialog which appears to
## complete the Xcode installation before running this script.
##

## Usage:
## cd to the mac_build directory of the boinc tree, for example:
##     cd [path]/boinc/mac_build
##
## then invoke this script as follows:
##      source BuildMacBOINC.sh [-dev] [-noclean] [-libstdc++] [-all] [-lib] [-client] [-zipapps] [-uc2] [-vboxwrapper] [-target targetName] [-setting name value] [-help]
## or
##      chmod +x BuildMacBOINC.sh
##      ./BuildMacBOINC.sh [-dev] [-noclean] [-libstdc++] [-all] [-lib] [-client] [-zipapps] [-uc2] [-vboxwrapper] [-target targetName] [-setting name value] [-help]
##
## optional arguments
## -dev         build the development (debug) version.
##              default is deployment (release) version.
##
## -noclean     don't do a "clean" of each target before building.
##              default is to clean all first.
##
## -libstdc++   build using libstdc++ instead of libc++
##
##
##  The following arguments determine which targets to build
##
## -all         build all targets (i.e. target "Build_All" -- this is the default)
##              except boinc_zip_test, testzlibconflict, UpperCase2 targets
##              (UC2-x86_64, UC2Gfx-x86_64 and slide_show-x86_64) and VBoxWrapper
##
## -lib         build the six libraries: libboinc_api.a, libboinc_graphics2.a,
##              libboinc.a, libboinc_opencl.a, libboinc_zip.a, jpeglib.a.
##
## -client      build two targets: boinc client and command-line utility boinc_cmd
##              (also builds libboinc.a if needed, since boinc_cmd requires it.)
##
## -zipapps     build two zip samples: boinc_zip_test and testzlibconflict
##
## -uc2         build the UpperCase2 targets: UC2-x86_64, UC2Gfx-x86_64 and
##              slide_show-x86_64
##
## -vboxwrapper build the VBoxWrapper target
##
## Both -lib and -client may be specified to build seven targets (no BOINC Manager)
##
## The following are used mainly for building the daily test builds:
##
## -target targetName build ONLY the one target specified by targetName
##
## -setting name value override setting 'name' to have the value 'value'
## Usually used along with -target, You can pass multipe -setting arguments.
