[R-SIG-Mac] Building from source problems.

[Rolf Turner]

QUESTION 1:
===========

Yesterday I sent out a cri de coeur in respect of not being
able to build R 2.10.0 from source on my Mac (OS X 10.4.11).

Simon Urbanek informed me that I could get a working R 2.10.0
from http://r.research.att.com/ which I duly did.  That went
O.K.

Then today, because of another problem that I encountered (see
below) I decided to go back to R 2.9.2.  I retrieved the
tar file from the ``Source code of older versions of R'' and
went through the ./configure and make routine.  Blow me down,
but didn't I get the same error that I got when trying to make
version 2.10.0:

Simon told me that the error that arose when I tried to make 2.10.0 was
due to trying to build a 64 bit version under a too-ancient version of
Mac OS X.  Is the 2.9.2 release configured to produce a 64 bit version?
I ***thought*** I had installed 2.9.2 from source, but maybe not ....

Is there any way I can tell it ***not*** to go for a 64-bit version?
(Surely there must be, since the r.research.att web site provides a
version which runs under Mac OS X 10.4.11.)

QUESTION 2:
===========

The reason that I decided to go back to R 2.9.2 was that I tried to
install the contributed package spatstat (version 1.17.0) from source
and got an error:

gcc -arch i386 -std=gnu99 -I/Library/Frameworks/R.framework/Resources/ 
include -I/Library/Frameworks/R.framework/Resources/include/i386  -I/ 
usr/local/include    -fPIC  -mtune=core2 -g -O2 -c Kborder.c -o  
Kborder.o
Kborder.c:1: error: bad value (core2) for -mtune= switch
make: *** [Kborder.o] Error 1
ERROR: compilation failed for package 'spatstat'

I thought this error must have resulted from the upgrade to 2.10.0.   
However
when I finally succeeded in backing off to 2.9.2 (by getting a binary  
from
the r.research.att site) I got exactly the same error under 2.9.2.

What is this error all about?  What can I do about it?  Is there any  
flag
I can set for configure (???) that will get rid that -mtune=core2 in
the call to gcc?  What is ``mtune'' all about?  What does ``core2''  
mean?

Sheesh! :-)

Thanks for any enlightenment.

	cheers,
