Hi phani sri,
Try set `FFLAGS=-fallow-argument-mismatch` and `FCFLAGS=-fallow-argument-mismatch` and let us know if that helps.

Hi Gregor, I have checked this, the code is using mpi. h not mpif. h. Dr. D. P. S. L. Kameswari On Fri, 17 Oct 2025, 5: 56 pm Gregor Corbin via discuss, <discuss@ mpich. org> wrote: Hi, let me guess: this code uses `include mpif. h` and is compiled

Hi,
let me guess: this code uses `include mpif.h` and is compiled with gfortran. If so, try to add `-fallow-argument-mismatch' to your compiler flags.
Explanation: With the include file, there are no explicit interfaces and the compiler generates an implicit interface from the call to `MPI_IRECV`. Having two calls with different argument types is an error since some gcc version (10 IIRC).
Cheers,
Gregor Corbin
