TYPE: bug fix
KEYWORDS: gfortran/10
SOURCE: Srikanth Yalavarthi (Marvell Semiconductor)
DESCRIPTION OF CHANGES:
Problem:
Due to argument inconsistencies, the WRF code will not compile with gfortran/10.
Here are some examples of incorrect Fortran argument usages:
```
Error: Rank mismatch between actual argument at (1) and actual argument at (2) (rank-1 and scalar)
wrf_io.f:7605:71:

The errors in the WRF infrastructure code can be eventually updated. However, the code from the FFTPACK library
will be left AS-IS. We are going to initially address all of the problems in a temporary fashion.
Temporary solution:
A compiler flag was added for the gfortran compiler to allow mismatched arguments, which enables the WRF system
to build. The new flag is only for versions of gfortran 10 and later. This change was introduced in the configure script,
which modifies all gfortran stanzas.
Permanent fix:
A complete fix requires changes in the Fortran sources for BOZ declarations and to fix mismatches in subroutine
arguments.
ISSUE:
Fixes #1250
LIST OF MODIFIED FILES:
M Makefile
M arch/configure.defaults
M configure
TESTS CONDUCTED:
1. Successfully built the master branch with GCC-10 on RPi4 Ubuntu-20.04 machine
2. Logic tested, where only GNU 10 and above are impacted.
3. Other compilers are not affected.
4. Jenkins testing is OK.
5. The DA variants have been tested also: I could build WRF / WRFPLUS / 3DVAR / 4DVAR

We put in a fix for this problem in the branch release-v4.2.1 If I test the top of the repository with GNU 10.1.0 (what we have access to, it seems to work OK. The original PR verified that WRF, WRFDA, WRFPLUS, and WRF4DVAR all worked. Would you verify that you have this hash: 28c18ee If GNU 10.2 finds other errors (in addition to those found by 10.1), would you be interested in putting together a pull request for this? Is this a bug that we have recently introduced? |

This error: gfortran: fatal error: Terminated signal terminated program f951 Seems to be related to OutOfMemory problems during compilation. I am having a similar problem during compilation with the same error, did you solve this? cheers |

WRF master branch build fails due to two issues which are a result of changes in GCC-10
As Mismatches between actual and dummy argument lists in a single file are now rejected with an error, gfortran would require additional flag "-fallow-argument-mismatch" to build the fortran sources,
`gfortran -fopenmp -O0 -ftree-vectorize -funroll-loops -march=armv8-a -w -ffree-form -ffree-line-length-none -fconvert=big-endian -frecord-marker=4 -o wrf_io.o -I/opt/ubuntu/libraries/glibc-2.31/netcdf-fortran/4.5.2-gcc-10.0.1/include -I../ioapi_share -c wrf_io.f

Changes were made in GCC-10 , in the way BOZ literal constants are handled. This would require "-fallow-invalid-boz" flag to passed to the fortran sources.
