[R-SIG-Mac] Compiling CC source: cc in R 2.12 vs gcc in R 2.13

[Richard R. Liu]

Hello,
 
I sent the following email to Duncan Temple Lang, who maintains Rlibstemmer, but
I suspect the problem is a general one.  Perhaps somebody here can tell me what
options have to be set for gcc -- or whether and how I can still use cc with R
2.13 -- in order to get a 32-bit version.  Thanks.
 
---------- Original email follows ----------
Hello Duncan,

Some time ago I had a problem with RStem which was solved in Rlibstemmer.  Since
then I have been using the latter, specifically Rlibstemmer_0.1-0.tar.gz.  Up
until R 2.12 the following recipe has worked for building a 32-/64-bit binary
for OS X:

----------
Download Rlibstemmer_0.1-0.tar.gz from http://www.omegahat.org/Rlibstemmer.
 Unpack it by double-clicking on it.  This will produce a folder Rlibstemmer.
 Navigate to Rlibstemmer/inst/libstemmer_c.  Modify Makefile as follows:  (1)
delete the line specifying the CFLAGS and (2) add examples/*.o to the files to
be cleaned.  Save the Makefile.

Now start Terminal and cd to the directory that contains the folder Rlibstemmer.
 Issue the command tar -czf Rlibstemmer.tar.gz Rlibstemmer/* to create a new
source package.  After that, create and install the 64-bit version of
Rlibstemmer as follows:

export CFLAGS="-arch x86_64 -m64 -Iinclude -fPIC"
export CCFLAGS="-arch x86_64 -m64"
R --arch=x86_64 CMD INSTALL Rlibstemmer.tar.gz

Then create and install the 32-bit version:

export CFLAGS="-arch i386 -m32 -Iinclude -fPIC"
export CCFLAGS="-arch i386 -m32"
R --arch=i386 CMD INSTALL --libs-only Rlibstemmer.tar.gz
----------

However, compiling for R 2.13, 32-bit version, no longer works.  Here is a log
of the run:

----------

rrl-macbookpro:Downloads sim$ export CCFLAGS="-arch i386 -m32"

----------

I notice that compiling for 2.12 invokes cc, whereas for 2.13 it is gcc-4.2.
 Can you suggest a fix for this problem?
