I'm not entirely sure where to start... but, the sequence to get me
where I am now runs something like this:


1. Upgraded to default/linux/x86/10.0 (actually, I chose the server
profile... no particular reason - except that this box is headless...)
when running my regular-ish "emerge -uDNav world" told me to do so -
saying that my old profile was deprecated.


2. Started following the howto for kolab - but, this package, it seems,
is far more problematic than I wish to deal with - I cancelled this
after the emerge stage had installed a few decompression tools - as I
read more about issues with the package under Gentoo.


3, (Possibly rashly) I did a "emerge -av --depclean" - and thereafter
things started to go screwy - eix and PHP failed, for example.


4. Tried to do a revdep-rebuild - which identified 4 packages - but
keeled over... having reported that the profile wasn't supported -
complaining about an issue with a Fortran compiler associated with
blas-reference, in-turn required by R (which I removed from world as I
no-longer need it.)


5. revdep-rebuild now fails with PHP5 - so, I tried removing and
re-installing PHP5... which also failed. There was a prominent warning
about my profile being un-supported, so I switched to "[1]
default/linux/x86/10.0 *" (as opposed to "[4]
default/linux/x86/10.0/server") hoping this might help.


6. PHP still won't install... and I can't even do an "emerge -uDNav
world" - and, now, apr won't build... apparently having some sort of
problem with finding gcc... I've attached the build log from
/var/tmp/portage/dev-libs/apr-util-1.3.9/work/apr-util-1.3.9/config.log.
revedep-rebuild also fails... this time with

Clutching at straws, I tried this:

$


I presume that this is a profile issue - but I'm unclear what the fault
might be... I'm reluctant to continue hacking as, I suspect, I'm more
likely to break things than stumble across an appropriate fix.


Can anyone tell me why emerge is having such a problem with my compiler
- and, hopefully, ideally, how best to resolve this?

yes, don't use locate. Also check the symlinks. Reset them with eselect gcc if
you have to.

Then try all your emerges with --tree you get a lot more helpfull output.
Also, when a dependency is missing revdep-rebuilt loves to fail. You can hunt
that down with --tree or just re--emerging the stuff.

And, did you actually check config.log?

There seems to be a mismatch between what you have installed (4.3.4) and what
emerge want's to use (4.1.2). I'd try eselect'ing the correct compiler as
Volker suggests, run env-update and source /etc/profile.

HTH...

Then try all your emerges with --tree you get a lot more helpfull output.
Also, when a dependency is missing revdep-rebuilt loves to fail. You can hunt
that down with --tree or just re--emerging the stuff.

Thanks very much, it looks as if "eselect gcc" was where I needed to
start. I've had to re-build gcc and then revdep-rebuild worked, and I'm
working through "emerge -uDNav world" - which seems to be running more
smoothly.


I was surprised that I managed to get into such a mess so easily... but
I seem to be back on track now.


Thanks.
