It's a [PERL] lie...

It's a [PERL] lie...

[Gary Thomas]

After three weeks, I've finally figured out why my PERL based
programs (Amanda in particular) don't run on my Poky/Yocto system.

I have my own distribution, derived from Poky, with some minor
tweaks.  In particular, I have some reduced DISTRO_FEATURES(*).
One of them that I had removed, 'largefile', was the root cause
of my PERL problems.  It turns out that PERL is the only package
that cares about this DISTRO_FEATURE and it builds incorrectly
if it's left out :-(  Adding this feature back into my settings
made PERL build properly and now Amanda runs as well.

My point/query is that if this setting is only used by PERL *and*
leaving it out breaks things anyway, shouldn't it just be removed
and the PERL recipes changed to assume that it was set?

* Note: I made these changes years ago, when I was new to OE/Poky
and still quite naive, and I don't recall why I removed 'largefile'.

According to grep it's perl, cmake and libarchive that respect the
largefile feature.

If perl is known to break without largefile it's simple enough to make
it error when building if the feature isn't enabled, but to be honest
should we just remove this feature as it's so infrequently used?

Indeed, I missed them in my zeal :-(  I new I was looking for something
that affected my problem, and perl was the key (I'm not using either
of the other packages)

I'd vote for at least fixing the perl recipe.  The problem is insidious;
it only fails at runtime and then in mysterious ways...  It also fails
on every architecture I tried (x86, ARM, PPC)
