# Script to build Macintosh 32-bit Intel library of curl-7.50.2 for
# use in building BOINC.
#
# by Charlie Fenton 7/21/06
# Updated 12/3/09 for OS 10.7 Lion and XCode 4.2
# Updated 6/25/12 for curl 7.26.0
# Updated 7/10/12 for Xcode 4.3 and later which are not at a fixed address
# Updated 2/11/14 for curl 7.35.0 with c-ares 1.10.0
# Updated 9/2/14 for bulding curl as 64-bit binary
# Updated 11/17/14 for curl 7.39.0 with c-ares 1.10.0
# Updated 12/11/15 for curl 7.46.0 with c-ares 1.10.0
# Updated 3/2/16 for curl 7.47.1 with c-ares 1.10.0
# Updated 9/10/16 for curl 7.50.2 with c-ares 1.11.0
# Updated 3/14/17 to patch curlrules.h to fix BOINC Manager compile error
#
## 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 curl-7.50.2 directory.
##     cd [path]/curl-7.50.2/
## then run this script:
##     source [path]/buildcurl.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
##
