First check the toolchain: which gcc gcc -dumpmachine You might need to revise your path and/or install 64 bit versions of the compilers. Actually, looking at the package list for SLES 10, I see that some packages have a -64bit variant, e.g. glibc-64bit 2.4 <http://www.novell.com/products/linuxpackages/server10/ppc/glibc-64bit.html> (Standard Shared Libraries (from the GNU C Library)) glibc-devel-64bit 2.4 <http://www.novell.com/products/linuxpackages/server10/ppc/glibc-devel-64bit.html> (Include Files and Libraries Mandatory for Development) but the gcc package does not, and the gcc-fortran-64bit 4.1.0 <http://www.novell.com/products/linuxpackages/server10/ppc/gcc-fortran-64bit.html> packages contains only libraries. So my guess is that there is one compiler that does both 32 bit and 64 bit compiling, but you need to set a compiler flag for the latter. I don't think messing with --build and --host is likely to do any good. ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
