Installing RPI::WiringPi for Perl
« on: January 21, 2017, 05:53:12 PM »
Hi,

I'm trying to install RPI::WiringPi from CPAN to play with an LCD and a few buttons - I want to use Perl because I'm already familiar with the language and because this might end up becoming a Squeezecenter plugin. I understand roughly what's involved in the process, but I don't have all the skills to troubleshoot it. Maybe someone could help me?

I started with a fresh piCore install (V3.10), plus extending the FS, etc. - I already have Squeezecenter and Squeezeplayer running.

Then I installed a few extensions based on my gut feeling, e.g. (not necessarily in this order):

  • perl5
  • wiringpi
  • wiringpi-dev
  • compile
  • binutils-dev
  • setuptools
  • gcc
  • gcc_base-dev
  • gcc_libs
  • gcc_libs-dev

among others. After each new extension is installed I do:

Code: [Select]
sudo perl -MCPAN -e shell
install RPi::WiringPi

But there's always an error somewhere, dependency errors, runtime errors, memory errors... Last one was apparently an I/O error! But I guess this one will go away if I reboot the Pi.

Now... is there an easier way to do this? Something pre-compiled for the Pi (B - armv6), or step-by-step instructions to compile this specific module? I can start it from scratch if needed (meaning, re-flash piCore 3.10 to the SD card), no big deal.

Thanks in advance,

VMat

First of all there are no piCore V3.10 version, actual version is 8.1.x Probably you are referring picoreplayer?

On piCore-8.1.5 installation of RPi::WiringPi fails. Same happenes installing it in Raspbian, so it is not piCore specific, it is a bug in the package. You can fix it yourself, report to its author, etc.

My personal advice to drop anything Perl at all and go for a usable language.

That's right, sorry. It's picoreplayer. I keep both in the same folder, and when I wrote my post I looked at one and thought of the other...

Oh, my... I was hoping you, of all people, would be the one to bring me good news... :)

I'm not going to give it up so quickly, though. It's good to know that it's a known bug. Do you know any forum threads on the subject, that I could get some clues from?

Thanks a lot,

VMat

Instead of trying to install directly from cpan, wny not download the  RPi::WiringPi source tarball and compile that instead?

I thought that's what cpan was doing in the background. But I will give it a try, thanks!
