# Script to build Macintosh Universal Intel library (i386 and x86_64)
# of FreeType for use in building BOINC graphics.
# The resulting library is at:
#   [path]/freetype-x.x.x/objs/.libs/libfreetype.a
# where x.x.x is the freetype version number

#
# by Charlie Fenton 7/27/12
# Updated 2/7/14 for OS 10.9
# Updated 4/8/15 to check for spaces in path
# Updated 1/5/16 for FreeType-2.6.2
# Updated 1/25/18 for any version of FreeType (changed only comments)
#
## This script requires OS 10.6 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.
#
## Where x.x.x is the freetype version number:
## In Terminal, CD to the freetype-x.x.x directory.
##     cd [path]/freetype-x.x.x/
## then run this script:
##     source [path]/buildfreetype.sh [ -clean ] [--prefix PATH]
##
## the -clean argument will force a full rebuild.
## if --prefix is given as absolute path the library is installed into there
## use -q or --quiet to redirect build output to /dev/null instead of /dev/stdout
##
