1# this is a build script for ARM-linux cross-compiling.
2# it builds miniperl on HOST and then perl for TARGET
3# this approach is like Perl-CE cross-compiling, and allows
4# for full TARGET perl (as opposed to renamed miniperl)
5
6# to skip Configure/build for HOST miniperl, pass "noconf" argument to this script
7
8# some trick is different, however - the file extension for objects files
9# are chosen to be .${CROSS_NAME}, .armo in our case
10
11# note how invoked Makefile.PL for cross-compilation:
12#   miniperl -MCross Makefile.PL
13
14# steps are:
15# - run HOST configure
16# - build HOST miniperl
17# given freshly-created HOST makefile and existing miniperl fix makefile
18# to use
