[FLASH-USERS] [EXT] Type mismatch for while running 'make'

Fri May 17 04:11:25 EDT 2024

Humm

Okay...  i do not know really why then the fortran compiler complains about type mismatch ...

Is this a compiler internal error?

Cheers,

Denis

dtMinLoc(1) is an integer. The first argument to MPI_Bcast is the start of the buffer being communicated and should match the type declared in the third argument, MPI_REAL or MPI_INTEGER. “Pgmin” in the 4th place is the rank of the broadcast origin, which is always an integer, in this case the process that owns the limiting time step.

Hi Adam
in MPI_Bcast dtMinloc(10 or extraHydroninfo are declared as REAL, but pgmin is INTEGER.
Cheers,
Denis

Hi Dennis,

I’m not sure what you mean. Gfortran complains here because the same subroutine, “MPI_Bcast”, is being called twice with different signatures, first with an integer argument then with a real, but are broadcasting to two different variables “dtMinLoc(1)” & “extraHydroInfo". GCC 10 introduced much stricter type checking and only allows this kind of function overloading with an explicit interface. The default behavior in FLASH is to use the “mpif.h” header file, which does not provide any interfaces.

In 4.8 we have added the option to use the mpi module instead by adding a line “USE_MPI=1” in your Makefile.h that should allow you to leave out the “allow-mismatch” flag.

Hi Adam
I am not sure about the validity of the allow-mismatch flag in this context.
You basically send a real  anf receive it as an integer ... this is not allowed in MPI and will
not garantee the validity of reveived message.

Basically i have to downgrade the gfortran compiler to v8.x to be able to compile this code,
any modern gcc compiler 12,13, 14 does not accept that and ... it is correct.

Cheers,
Denis

PS this is only the first hit, there are still many other place in the code where the same error is done
with Bcast.

Hi Srijan,

See the solution offered here: https://flash.rochester.edu/pipermail/flash-users/2023-June/004054.html
And the links within.

Dear Users,
I am trying to build and install Flash 4.8. I followed the steps given in the manual:
1. unpack the FLASH source code distribution.
 tar -xvf FLASHX.Y.tar
2. Type
     ./setup Sedov -auto    (SUCCESS)
3. Tried to compile with:
cd object
make
and I get the following error: Type mismatch between actual argument at (1) and actual argument at (2) (REAL(8)/INTEGER(4))
I have attached a screenshot of my terminal if that helps.

Thanks in advance!
