# this is a build script for ARM-linux cross-compiling.
# it builds miniperl on HOST and then perl for TARGET
# this approach is like Perl-CE cross-compiling, and allows
# for full TARGET perl (as opposed to renamed miniperl)

# to skip Configure/build for HOST miniperl, pass "noconf" argument to this script

# some trick is different, however - the file extension for objects files
# are choosen to be .${CROSS_NAME}, .armo in our case

# note how invoked Makefile.PL for cross-compilation:
#   miniperl -MCross Makefile.PL

# steps are:
# - run HOST configure
# - build HOST miniperl
# given freshly-created HOST makefile and existing miniperl fix makefile
# to use
