# Script to build Macintosh Universal Binary library of c-ares-1.6.0 for
# use in building BOINC.
#
# Note: reverted to c-ares 1.6.0 from 1.7.0 because the newer c-ares has 
# problems resolving host names on OS 10.6 with default settings when used 
# with AT&T U-Verse 2Wire gateway routers and Airport.
#
# by Charlie Fenton 7/21/06
# Updated 4/3/10
#
## In Terminal, CD to the c-ares-1.6.0 directory.
##     cd [path]/c-ares-1.6.0/
## then run this script:
##     source [path]/buildc-ares.sh [ -clean ] [ -gcc33 ]
##
## the -clean argument will force a full rebuild.
##
## the -gcc33 argument will cause the PowerPC build to use gcc-3.3
## otherwise both architectures will be built using gcc_4.0
##
## Use -gcc33 if you need to link with a project application using BOINC 
## libraries built with gcc-3.3 for backward compatibility to OS 10.3.0
##
## Build with gcc-4.0 to link with the BOINC client
