   7README.riscos - Perl version 5 for RISC OS
   8
   9=head1 DESCRIPTION
  10
  11This document gives instructions for building Perl for RISC OS. It is
  12complicated by the need to cross compile. There is a binary version of
  13perl available from L<http://www.cp15.org/perl/> which you may wish to
  14use instead of trying to compile it yourself.
  15
  16=head1 BUILD
  17
  18You need an installed and working gccsdk cross compiler
  19L<http://gccsdk.riscos.info/> and REXEN
  20L<http://www.cp15.org/programming/>
  21
  22Firstly, copy the source and build a native copy of perl for your host
  23system.
  24Then, in the source to be cross compiled:
  25
  26=over 4
  27
  28=item
  29
  30    $ ./Configure
  31
  32=item
  33
  34Select the riscos hint file. The default answers for the rest of the
  35questions are usually sufficient.
  36
  37Note that, if you wish to run Configure non-interactively (see the INSTALL
  38document for details), to have it select the correct hint file, you'll
  39need to provide the argument -Dhintfile=riscos on the Configure
  40command-line.
  41
  42=item
  43
  44    $ make miniperl
  45
  46=item
  47
  48This should build miniperl and then fail when it tries to run it.
  49
  50=item
  51
  52Copy the miniperl executable from the native build done earlier to
  53replace the cross compiled miniperl.
  54
  55=item
  56
  57    $ make
  58
  59=item
  60
  61This will use miniperl to complete the rest of the build.
