Hi Hui, this also did not work.It is ending up with the error: collect2: error: ld returned 1 exit status. On Fri, 17 Oct 2025 at 21:11, Zhou, Hui <[email protected]> wrote:

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.

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,
