The R-admin manual says to use CC="gcc -m64" CXX="gxx -m64" F77="gfortran -m64" FC="gfortran -m64" in several places: can you try following that (with g77 on your old OS, and presumably not FC if you don't have an F90 compiler). > It's not, and unfortunately I'm at a loss to what the problem is. > Here's the last few lines of the above configure command: > > checking for Fortran 77 libraries of g77... -L/usr/local/lib64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/../../../../lib64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/../../.. -L/lib/../lib64 > -L/usr/lib/../lib64 -lfrtbegin -lg2c -lm -lgcc_s_64 > checking how to get verbose linking output from gcc -std=gnu99... -v > checking for C libraries of gcc -std=gnu99... -L/usr/local/lib64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/../../../../lib64 > -L/usr/lib/gcc/ppc64-redhat-linux/3.4.6/../../.. -L/lib/../lib64 > -L/usr/lib/../lib64 -lgcc_s_64 > checking for dummy main to link with Fortran 77 libraries... none > checking for Fortran 77 name-mangling scheme... lower case, underscore, > extra underscore > checking whether g77 appends underscores to external names... yes > checking whether g77 appends extra underscores to external names... yes > 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? > > Here's what looks to be the relevant part from config.log: > configure:32383: checking whether mixed C/Fortran code can be run > /usr/bin/ld: skipping incompatible > /usr/lib/gcc/ppc64-redhat-linux/3.4.6/libgcc_s_64.so when searching for > -lgcc_s_64 > /usr/bin/ld: skipping incompatible > /usr/lib/gcc/ppc64-redhat-linux/3.4.6/libgcc_s_64.so when searching for > -lgcc_s_64 > /usr/bin/ld: cannot find -lgcc_s_64 > collect2: ld returned 1 exit status > configure:32447: WARNING: cannot run mixed C/Fortran code > configure:32449: error: Maybe check LDFLAGS for paths to Fortran libraries? > > This implies that configure is compiling the code in 32 bit mode (which > is why it's skipping libgcc_s_64.o > > I guess my questions are: has anyone compiled this for this system?
