# Script to build Macintosh Universal Intel library (i386 and x86_64) 
# of ftgl-2.1.3~rc5 for use in building BOINC graphics.
# The resulting library is at:
#   [path]/ftgl-2.1.3~rc5/src/.libs/libftgl.a
#
# by Charlie Fenton 7/27/12
# Updated 2/7/14 for OS 10.9
#
## 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.
#
## In Terminal, CD to the ftgl-2.1.3~rc5 directory.
##     cd [path]/ftgl-2.1.3~rc5/
## then run this script:
##     source [path]/buildFTGL.sh [ -clean ]
##
## the -clean argument will force a full rebuild.
