[R-SIG-Mac] gfortran error: unrecognized command line option "-arch"

[Markus Baden]

Hi,

I'm using R version 2.7.0 (2008-04-22) on my MacBook Pro running Mac  
OS X.5.2. I installed R using the universal binary from CRAN, so I  
guess my R uses the gfortran compiler provided in the binary although  
I have also have a gfortran coming with my fink installation.

When installing packages from source I often get the error message  
"unrecognized command line option "-arch". Like in:

gfortran -arch ppc  -isysroot /Developer/SDKs/MacOSX10.4u.sdk   -fPIC   
-g -O2 -c rf-common.f -o rf-common.o
f951: error: unrecognized command line option "-arch"
make: *** [rf-common.o] Error 1

Does anyone now how to fix this?

Below is an example with the package "robustbase" (of course you can  
install the mac.binary from CRAN, and I have successfully done so,  
this just illustrates the error I get also from different packages  
like fAsset which are not available as mac.binary)

Best regards,

Markus
