Matrix does not build with R trunk since Oct.

Look. I don't see this as "my" problem - as far as I am concerned, I have donated my time - and over and over - to testing pre-released code. I am not using pre-released code for production work. If the released code in 3.0 does not work correctly in 6 weeks' time, I just don't upgrade. No loss for me there.

I don't know why it is degenerating into another distraction about some people's egos.

room for testing. 

Anyway neither Matrix 1.0-11 (current) nor

1.0-9 (sept

2012) build with current R trunk.  The 

last time

it did was 1. 0-9 on 3rd october over 4 months ago.

So it

appears to be due to change inside r trunk in sept

or early

oct. 

No problem here - Matrix 1.0-11 and R-devel build

just fine

with your flags (tested on Ubuntu 12.10, x86_64).

If in doubt, please remove R-devel and checkout a

fresh

copy. Also FWIW it's a bad practice to build inside

the

sources - it often causes all sorts of problems

when you try

to track the sources and stale files are probably

what's

hitting you.

FWIW: This is likely not the problem you're

mentioning, but

some recent gcc versions break and LTO is also

known to

cause issues depending on the compiler version, so

tread

lightly on the cutting edge.

Here is a fairly similar post:
http://r.789695.n4.nabble.com/Build-from-Source-fails-on-Loading-required-package-Matrix-td4640371.html

The eventual "solution" of that thread seems to be

building from tar ball, which is quite beside the whole
point of building from svn trunk.

And how is that relevant to what I said? Did you follow the
advice I sent? If you did and still have an issue, post
*exact* details on what you did, what system and tools you
are using. 

FWIW, it is very unproductive to talk about "bad

practice" - in a hand-waving undocumented/unsubstantiated
manner

Building in sources has two problems: a) the content of the
source tree can change so subsequent builds can be different
from the clean one - you cannot undo that and b) if you
update the sources stale files from previous builds can
break the build. 

If solving your problems is "unproductive" then I'm not
surprised you have them for 4 moths now.

- and options that might or might not work. If

"--enable-lto" (or any other options, or build within the
dev directory) does not work reliably, it should be either
disabled/removed, or documented, or both.

R cannot test all aspects of a compiler and detect all its
bugs. It is *your* responsibility to provide a working
compiler - if you are unwilling to do that, R cannot do
anything about that.

Anyway, it has not been working for over 4 months.

That is not true, obviously, and I have presented a
counter-example. It may not have been working for *you* and
it's likely a problem in your setup (given your lack of
cooperation there is no way to tell for sure). We cannot
prevent user errors. We can try to point people in the right
direction, but if they refuse to listen it's on their head.

You have about 6 weeks before this becomes a big

problem - "big" as in "wide-spread".

You are yet to show that this is a problem in R at all. You
failed to follow the basic instructions in the FAQ.
