The R Project SVN R-packages

#
# unix-style build of universal R.app
#
# it relies on Xcode to create the bundle and compiles the binary itself
# using Apple's and FSF gcc. it works only on Intel Macs and only if you
# have FSF gcc installed in /usr/local/gcc4.0
# this is a temporary hack until the compiler situation is sorted out.
#
# additional variables that influence the build:
# STYLE  - defined the Xcode configuration to use when building R.app
#          it has no effect on the binary itself - use xxFLAGS as usual
#          for that
# ARCH   - defines the architecture to build for, but doesn't automatically
#          add the -arch parameter aas it's not always supported
#          default is the native architecture
# OBJCC/OBJCFLAGS - special compiler/flags for Obj-C files (default is to
#          use OBJCC=$CC and OBJCFLAGS='')
#
# targets:
# R.$(ARCH)  - binary for $(ARCH)
# R          - universal binary for R (calls make for i386 and ppc)
# R.app      - universal R.app bundle (uses Xcode and R target)
# clean      - as usual
#

# get the native architecture (override on the command line)
