NAME
       perlriscos - Perl version 5 for RISC OS

DESCRIPTION
       This document gives instructions for building Perl for RISC OS. It is
       complicated by the need to cross-compile. There is a binary version of
       perl available from <https://www.cp15.org/perl/> which you may wish to
       use instead of trying to compile it yourself.

BUILD
       You need an installed and working GCCSDK
       <https://www.riscos.info/downloads/gccsdk/latest/> cross-compiler and
       REXEN <https://www.cp15.org/programming/>.

       First, copy the source and build a native copy of perl for your host
       system.  Then, in the source to be cross-compiled:

       1.
               $ ./Configure

       2.  Select the RISC OS hint file (hints/riscos.sh).  The default
           answers for the rest of the questions are usually sufficient.

           Note that, if you wish to run "Configure" non-interactively (see
           the INSTALL document for details), to have it select the correct
           hint file, you'll need to provide the argument "-Dhintfile=riscos"
           on the "Configure" command-line.

       3.
               $ make miniperl

       4.  This should build "miniperl" and then fail when it tries to run it.

       5.  Copy the miniperl executable from the native build done earlier to
           replace the cross-compiled miniperl.

       6.
               $ make

       7.  This will use "miniperl" to complete the rest of the build.
