Hello folks I am attempting to install R on a series of Apple G5 machines which are running Yellow Dog Linux 6.0. Has anyone had success with this, and is there something I should be doing which I am not? Upon configure, I receive the error message: checking whether mixed C/Fortran code can be run... configure: WARNING: cannot run mixed C/Fortran code configure: error: Maybe check LDFLAGS for paths to Fortran libraries? libg2c.so is found in the following places: /usr/lib/libg2c.so.0 /usr/lib/libg2c.so.0.0.0 /usr/lib/gcc/ppc64-yellowdog-linux/3.4.6/libg2c.so /usr/lib/gcc/ppc64-yellowdog-linux/3.4.6/64/libg2c.so So I've tried the following four LDFLAGS variants, both by exporting LDFLAGS in the bash shell and setting it in config.site: LDFLAGS='-L/usr/lib -L/usr/lib/gcc/ppc64-yellowdog-linux/3.4.6 -L/usr/lib/gcc/ppc64-yellowdog-linux/3.4.6/64' LDFLAGS='-L/usr/lib' LDFLAGS='-L/usr/lib/gcc/ppc64-yellowdog-linux/3.4.6' LDFLAGS='-L/usr/lib/gcc/ppc64-yellowdog-linux/3.4.6/64' Still no luck. Any ideas? Thanks, -ben
