.SH NAME
perlriscos \- Perl version 5 for RISC OS
.SH DESCRIPTION
.IX Header "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.
.SH BUILD
.IX Header "BUILD"
You need an installed and working
GCCSDK <https://www.riscos.info/downloads/gccsdk/latest/> cross\-compiler
and REXEN <https://www.cp15.org/programming/>.
.PP
First, 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 RISC OS hint file (\fIhints/riscos.sh\fR).
The default answers for the rest of the questions are usually sufficient.
.Sp
Note that, if you wish to run \f(CW\*(C`Configure\*(C'\fR non\-interactively
(see the \fIINSTALL\fR document for details), to have it select the correct hint
file, you\*(Aqll need to provide the argument \f(CW\*(C`\-Dhintfile=riscos\*(C'\fR on the
\&\f(CW\*(C`Configure\*(C'\fR command\-line.
.IP 3. 4
.Vb 1
\&    $ make miniperl
.Ve
.IP 4. 4
This should build \f(CW\*(C`miniperl\*(C'\fR and then fail when it tries to run it.
.IP 5. 4
Copy the \fIminiperl\fR executable from the native build done earlier to
replace the cross\-compiled \fIminiperl\fR.
.IP 6. 4
.Vb 1
\&    $ make
.Ve
.IP 7. 4
This will use \f(CW\*(C`miniperl\*(C'\fR to complete the rest of the build.
