[petsc-users] How to exclude -C compiler option (VecGetArray in Fortran)

[Danyang Su]

Hi All,

I get some problem in VecGetArray in Fortran, which I guess is due to 
the default -C compiler option.

Current compiler option are:
$ make ksp_inhm
/cygdrive/c/cygwin/packages/petsc-3.4.2/bin/win32fe/win32fe ifort -c  
-MT -Z7 -fpp  -I/cygdrive/c/cygwin/packages/petsc-3.4.2/in
clude 
-I/cygdrive/c/cygwin/packages/petsc-3.4.2/arch-mswin-c-debug/include 
-I/cygdrive/c/cygwin/packages/parmetis-4.0.3/include
-I/cygdrive/c/cygwin/packages/metis-5.1.0/include -I/cygdrive/c/Program\ 
Files/MPICH2/include    -o ksp_inhm.o ksp_inhm.F90
/cygdrive/c/cygwin/packages/petsc-3.4.2/bin/win32fe/win32fe cl -MT 
-wd4996 -Z7  -o ksp_inhm_d ksp_inhm.o  -L/cygdrive/c/cygwin/p
ackages/petsc-3.4.2/arch-mswin-c-debug/lib  -lpetsc -lflapack -lfblas 
/cygdrive/c/cygwin/packages/parmetis-4.0.3/build/libparmet
is/Release/parmetis.lib 
/cygdrive/c/cygwin/packages/metis-5.1.0/build/libmetis/Release/metis.lib 
/cygdrive/c/Program\ Files/MPIC
H2/lib/fmpich2.lib /cygdrive/c/Program\ Files/MPICH2/lib/fmpich2g.lib 
/cygdrive/c/Program\ Files/MPICH2/lib/mpi.lib Gdi32.lib Us
er32.lib Advapi32.lib Kernel32.lib Ws2_32.lib


Relevant codes are as follows:

#define xx_a(ib) xx_v(xx_i + (ib))
       PetscScalar :: xx_v(1)
       PetscOffset :: xx_i
...
call VecGetArray(x, xx_v, xx_i, ierr)
write(*, 90) istart+1, xx_a(istart+1), iend, xx_a(iend)    !istart and 
iend are the ownership range
90          format ('x(', i6, ') = ',e11.4, ' x(', i6, ') = ',e11.4)
call VecRestoreArray(x, xx_v, xx_i, ierr)

The output (xx_a(istart+1), xx_a(iend)) is CORRECT for the processor 0, 
but INCORRECT for the other processors.

I found in the manual that for the fortran user, the compiler option -C 
should not be used. How I can set this option?

Thanks and regards,

Danyang
