# 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
#
## 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] [-libc++] [-c++11] [-all] [-lib] [-client] [-help]
## or
##      chmod +x BuildMacBOINC.sh
##      ./BuildMacBOINC.sh [-dev] [-noclean] [-libc++] [-c++11] [-all] [-lib] [-client] [-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.
##
## -libc++      build using libc++ instead of libstdc++ (requires OS 10.7)
##
## -c++11       build using c++11 language dialect instead of default (requires libc++)
##
##  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_graphics2.a,
##              libboinc.a, libboinc_opencl.a, libboinc_zip.a, jpeglib.a and the
##              utility application MakeAppIcon_h.
##
## -client      build two targets: boinc client and command-line utility boinc_cmd
##              (also builds libboinc.a if needed, since boinc_cmd requires it.)
##
## Both -lib and -client may be specified to build seven targets (no BOINC Manager)
