[oe] pcre staging (was: Re: new staging breaks apache2)

[Frans Meulenbroeks]

Hi,

I've dived into this problem.
The root cause is that pcre-config is not staged properly for package pcre
No idea why, maybe because it is part of the -dev package.
I tried to dive into this and peeked at classes/autotools.bbclass but
didn't manage to find the cause
(or maybe I did, but in that case I didn't find the fix).

What I saw were three references to STAGE_TEMP_PREFIX . However a grep
-r on my openembedded dir did not deliver an indication on where this
var is set.
so either this is the problem, or I am totally lost wrt this issue.

Anyway, I've fixed things for now by re-adding do_stage and explicitly
stage pcre-config.
This works and solves the breakage I had introduced by this.
Apache2 builds fine with this fix.

Looking for an expert opinion on how to really fix this

Frans.

PS: probably I would prefer it if the STAGE_TEMP dir remains and is
not removed. This could help diagnosing things.
