Alix board - perl exited on signal 4

Den

Hi,

I'm trying out pfSense on my Alix 2D13 and I see a bunch of messages like this in my system.log

pfSense kernel: pid 96532 (perl), uid 0: exited on signal 4 (core dumped)

It's a fresh install of full pfSense 2.2.6 (not a nano - I use a microdrive)

When I open perl.core in a viewer I see /usr/pbi/lightsquid-i386/local/bin/perl5.14.4 among other pieces of text. Lightsquid doesn't work, of course.

BTW I was very surprised to find that squid3 brought its own version of perl (5.18.4). I would expect that if 2 packages of a distribution are depending on a 3rd package and all 3 are installed using distro's package manager, that 3rd would be shared by the other 2.

But anyway, I'm not sure if squid is actually using it. Because when I did


cd  /usr/pbi/squid-i386/local/bin
./perl -v

I got "Illegal instruction (core dumped)" and perl.core dumped in that folder also contained string /usr/pbi/lightsquid-i386/local/bin/perl5.14.4. Squid seems to work ok though (transparent mode) - at least access.log grows.

I googled a bit and my understanding is that illegal instruction (aka signal 4), means that pearl was compiled with some instruction set that my Geode doesn't fully support. I searched system.log for "signal 4" and perl is the only app exhibiting this problem.

So, is there a way to sort this out? Compiling my own copy of perl is not an option and I don't really want to try the nano version.

Please note that I'm not unix-savvy.

Ok, in case someone googles this up:

Uninstall lightsquid and clean up as described here http://doc.pfsense.org/index.php/Lightsquid_Troubleshooting

Then install perl from FreeBSD repo using shell:


pkg
pkg update
pkg install perl5
rehash
perl -v

Install lightsquid through Web UI and confirm it didn't break perl by running "perl -v". And clean up:


rm -rf /usr/pbi/squid-i386/local/lib/perl5
rm -rf /usr/pbi/squid-i386/local/bin/perl*
rm -rf /usr/pbi/lightsquid-i386/local/lib/perl5
rm -rf /usr/pbi/lightsquid-i386/local/bin/perl*
find / -name perl.core -exec rm {} \;

Graphs were failing with HTTP 500 - Internal Server Error. I ran these commands


cd /usr/local/www/lightsquid
./check-setup.pl

And it said "no: GD.PM found, please install or set $graphreport=0 to disable". Installing p5-GD fixed the problem:


pkg install p5-GD

I must say I'm disappointed about how packages are organized in pfSense. My impression so far is that it's just a set of disjoint poorly maintained packages…

That's the nature of PBIs, which are gone in 2.3.
