.SH "NAME"
perlriscos \- Perl version 5 for RISC OS
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This document gives instructions for building Perl for \s-1RISC OS.\s0 It is
complicated by the need to cross compile. There is a binary version of
perl available from <http://www.cp15.org/perl/> which you may wish to
use instead of trying to compile it yourself.
.SH "BUILD"
.IX Header "BUILD"
You need an installed and working gccsdk cross compiler
<http://gccsdk.riscos.info/> and \s-1REXEN\s0
<http://www.cp15.org/programming/>
.PP
Firstly, copy the source and build a native copy of perl for your host
system.
Then, in the source to be cross compiled:
.IP "1." 4
.Vb 1
\&    $ ./Configure
.Ve
.IP "2." 4
Select the riscos hint file. The default answers for the rest of the
questions are usually sufficient.
.Sp
Note that, if you wish to run Configure non-interactively (see the \s-1INSTALL\s0
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.
.IP "3." 4
.Vb 1
\&    $ make miniperl
.Ve
.IP "4." 4
This should build miniperl and then fail when it tries to run it.
.IP "5." 4
Copy the miniperl executable from the native build done earlier to
replace the cross compiled miniperl.
.IP "6." 4
.Vb 1
\&    $ make
.Ve
.IP "7." 4
This will use miniperl to complete the rest of the build.
