After a difficult installation of threaded Perl 5.14.2, running this installed Perl produces only segmentation faults eg on attempting to run cpan.

The unit its installed on is a qnap NAS, which I understand has a non x86 'arm' processor:

uname -a
Linux NASC2089B 2.6.33.2 #1 Tue Aug 16 00:31:52 CST 2011 armv5tel unkn

To complete the Make process, I had to tweak some of the settings in the Makefile. I tried to put the link in here but apparently some links are not allowed. Basically the change was to invoke Miniperl rather than perl for the buildtoc function. Otherwise installation would stall at:

./perl -f -Ilib pod/buildtoc --build-toc -q

(with the nabble forum changes, miniperl rather than perl, executes 'buildtoc'). The poster referenced the issue as cross compiling one, though I haven't been able to work out exactly what cross compiling means.

My programming skills are rudimentary.

I wonder if part of the problem is because of the 'Optware' package system, which uses iPKG system. Applications installed via iPKG system are said to be installed in a chroot environment, though I can't locate a bash file within the Optware directory.

iPKG offered an older version of Perl, which easiy installed on my NAS but unfortunately was not suitable for the program I wanted to install (swish-e)

perl -V is one of the few things I can do with the installation and produces:

Anyway, if anyone can get this happening, I'll go find a monastery to learn to meditate deeper than a zen monk
