[mvapich-discuss] Configure bug in romio

[Glaesemann, Kurt R]

This file:

src/mpi/romio/confdb/aclocal_romio.m4



Has the following code in it (which is then used to generate the configure script).  The last line needs to add $FFLAGS so that compiler options the effect KIND will be in effect.  This is useful for the nagfor -kind=byte option, which seems to work everywhere else in the MVAPICH2 configure process.





AC_MSG_CHECKING([for Fortran 90 KIND parameter for 8-byte integers])

cat <<EOF > conftest.$ac_f90ext

      program main

      integer i

      i = selected_int_kind(16)

      open(8, file="conftest.out", form="formatted")

      write (8,*) i

      close(8)

      stop

      end

EOF

if test -z "$FC" ; then

   FC=f90

fi
if $FC -o conftest$EXEEXT conftest.$ac_f90ext >/dev/null 2>&1 ; then
