README.riscos - Perl version 5 for RISC OS


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 <> which you may wish to use instead of trying to compile it yourself.


You need an installed and working gccsdk cross compiler <> and REXEN <>

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

    $ ./Configure
o Select the riscos hint file. 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.


    $ make miniperl
o This should build miniperl and then fail when it tries to run it.
o Copy the miniperl executable from the native build done earlier to replace the cross compiled miniperl.

    $ make
o This will use miniperl to complete the rest of the build.
