Dear Mr.
   I have some problems when compiling the newest version of RegCM-4.3.5 . I download the .tar.gz file on the website and compile the model. After ./configure --enable-clm CC=icc FC=ifort MPIFC=mpiifort ,and make .
 
1. When it making /Main/mpplib/mod_mppparam.F90 ,an error occured .
Here are the details:
 
mod_mppparam.F90(464): error #6404: This name does not have a type, and must have an explicit type.   [MPI_STATUS_IGNORE]
                  cartesian_communicator,mpi_status_ignore,mpierr)
-----------------------------------------^
mod_mppparam.F90(588): error #6404: This name does not have a type, and must have an explicit type.   [MPI_PROC_NULL]
    ma%top         = mpi_proc_null
---------------------^
compilation aborted for mod_mppparam.F90 (code 1)
 
Then I comment out the two lines in the mod_mppparam.F90
 
!#ifdef MPI_SERIAL
  integer(ik4) mpi_status_ignore(mpi_status_size)
  integer(ik4) , parameter :: mpi_proc_null = -2
!#endif
 
and compiler can continue.
 
2.When it making /Main/mod_regcm_interface.F90 , another error occured .
 Here are the details:
 
mod_regcm_interface.F90(90): error #6404: This name does not have a type, and must have an explicit type.   [MPI_ERRORS_RETURN]
    call mpi_comm_set_errhandler(mycomm, mpi_errors_return, ierr)
 
I searched all the directories, the .F90 files and the .f90 files ,and I cannot find where the subroutine is. That is very odd.
My compiler is Intel Composer XE  2011 sp1.8.273 , MPIFC is mpiifort . I also used openmpi and mpich to compile, which yielded the same errors.
Why I cannot compile the model. Any help or suggestions will be greatly appreciated. Thank you very much !
 
Best regards !
