README.riscos \- Perl version 5 for RISC OS
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This document gives instructions for building Perl for \s-1RISC\s0 \s-1OS\s0. 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.
.SH "BUILD"
.IX Header "BUILD"
You need an installed and working gccsdk cross compiler
and \s-1REXEN\s0
.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 "\(bu" 4
.Sp
.Vb 1
\& $ ./Configure
.Ve
.IP "\(bu" 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 "\(bu" 4
.Sp
.Vb 1
\& $ make miniperl
.Ve
.IP "\(bu" 4
This should build miniperl and then fail when it tries to run it.
.IP "\(bu" 4
Copy the miniperl executable from the native build done earlier to
replace the cross compiled miniperl.
.IP "\(bu" 4
.Sp
.Vb 1
\& $ make
.Ve
.IP "\(bu" 4
This will use miniperl to complete the rest of the build.
