Hi,
I've found that the default options of gcc and g77 on alpha produce an
executable that suffers from floating exceptions. There seems to be a
problem with the configure scripts that prevents the --with-f77 option
working correctly. The configure script tests that f77 is running by
attempting to compile and link a dummy program - the link step seems
broken on the alpha (it doesn't like the command
f77 -o conftest conftest.f -L/usr/local/lib
The command works fine without the -L switch.
)
my workaround was to remove $LIBS from the line
ac_link='${F77-f77} -o conftest${ac_exeext} $FFLAGS $LDFLAGS
conftest.$ac_ext $L
IBS 1>&5'
but a better alternative may be to just use the fortran compiler to
produce an object file rather than an executable.
R configured using the following options passes "make test"
