In the mean time, do you mind if we take one or two stabs in the

So, if I'm not mistaken, it seems your only problem now is
compiling a
package from source, and you're getting some "mtune=core2" problem,
right?
Ack-chewally I have now installed, from CRAN, the 2.10.0 binary
designed
for Tiger, which Simon Urbanek built especially for me, and which
eschews the "mtune=core2" flag. With this binary I can now build
spatstat from source without hiccups. (Thank you Simon!)
So I guess I don't really have *any* problems as it stands.
I'd just kind of like to get *everything* working, seamlessly.
But I'm getting the impression that this will require upgrading
my OS from Tiger to the latest. I have emailed our IT people
to investigate whether this is a possibility. Have not yet heard
back from them ....
THIS IS PROBABLY A BAD IDEA, BUT ...
If we can't get your compiler to support these optimizations (maybe
because we can't get gcc-4.2 on there), then how about we just don't
use those optimizations when compiling? I'm not sure if that will
cause problems, but perhaps we can try?
This was actually suggested to me by someone else, offlist,
with less detail. I didn't have the nerve to try.
Can you find where this is defined in your install? Doing:
$ cd /Library/Frameworks/R.framework/Versions/2.10
$ grep -r mtune=core2 .
for me brings up one file:
./Resources/bin/libtool:LTCFLAGS="-mtune=core2 -g -O2"
Does it for you?
Just grepping in
/Library/Frameworks/R.framework/Versions/2.10/Resources/bin/libtool
gives the line that you found.
I wonder what happens if you just comment that line out and insert
below it:
LTCFLAGS="-g -O2"
I guess that Simon has set things somehow so that this flag doesn't
get used (???) under the Tiger OS, since, as I said above, the
build from source now works for me. So the comment-out and re-define
trick is not necessary. I could re-install R using the ``non-
special''
binary (with which I was getting the problem) and see if your trick
works
with that, but that would seem to be only of academic interest at
this
stage. It might be an interesting learning experience for me, but I
really should be getting on with proper work --- as should the rest
of
you whom I've been pestering about this stuff, I guess! :-)
Would all of your woes go away?
As I said, it's probably a bad idea, but if you're brave, it might be
worth a try.
(I've been sitting on this email for a while now, because I don't
want
to make boneheaded suggestions in public, but my xcode d/l is @ 75%
and I didn't want to leave you hanging for the rest of the day).
Any suggestion from you is almost certain to be far less
bone-headed than anything I might do on my own.
Sorry for muddling about on this. I have trouble keeping my
head clear as to what I need to do (as opposed to should or
could do, or want to do).
Bottom line: I seem to be OK now, for the time being at least.
To keep on being OK, I probably need to upgrade my OS.
Thanks to everyone for their help and for putting up with my
often confused and sometimes grumpy questions.
cheers,
Rolf
