64bit R for intel

I am about to invest into a new xserve and I was wondering what was  
the status on the 64-bit release of R for the intel chips (I need to  
break that 4GB limit...)

TIA,

Simon.

Unfortunately I still have no access to a Mac Pro machine, so I can't  
test it. In theory it should work as there is no problem building 64- 
bit ppc binary (i.e. the R sources should have no 32-bit vs 64-bit  
issues on a Mac). In practice there may be some problems lurking in  
the dark because of the compilers (the gcc 4.0.3 we use for the  
current build doesn't have 64-bit Intel support). A possible way is  
to use Apple compiler and maybe HPC gfortran. I can try to build such  
binary, but I'll need some owner of Mac Pro to test it (I'll post it  
to the R Mac page). Of course the same restrictions that apply to the  
ppc 64-bit version apply here as well (no Cocoa and GUI, need for  
custom X11 client etc.).

Cheers,
Simon

Simon and Simon,
I'll gladly test the build and report....
Cheers,

I'm glad to report that 64-bit R compiles and passes make check on  
Mac Pro (thanks to Jan de Leeuw for providing me with access to his  
machine).

Quick guide:
- get gfortran 4.2.0 for Intel from HPC pages (http:// 
hpc.sourceforge.net/) and install it ( sudo tar fvxz gfortran-intel- 
bin.tar.gz -C /
- get Darwin driver for gfortran (e.g. from my pages, run in terminal:
sudo bash
cd /usr/local/bin
mv gfortran i686-apple-darwin8-gfortran-4.2.0
curl -O http://r.research.att.com/gfortran
chmod a+x gfortran

Add the compiler to your PATH

export PATH=/usr/local/bin:$PATH

get R sources, configure and build. For my test I used the following  
flags:

../R24-branch/configure CC='gcc -arch x86_64' CXX='g++ -arch x86_64'  
F77='gfortran -arch x86_64' FC='gfortran -arch x86_64' --with-blas='- 
framework vecLib' --with-lapack --without-x CPPFLAGS=-I/usr/local/ 
include LDFLAGS='-L/usr/local/lib/x86_64 -L/usr/local/lib'  
r_arch=x86_64 --with-system-zlib --build=x86_64-apple-darwin8.8.1

If you don't have 64-bit readline, add --without-readline. If you  
install the above (make ; make install), it will add 64-bit support  
to your existing R framework (I didn't test the framework itself,  
though). Remove the r_arch flag if you want single-arch R.

Cheers,
Simon
