compiling hspf cbp on ubuntu 20.04

Compiler and Fortran version info

• gfortran-9 (see below for ls train)

  /usr/bin/f77 -> /etc/alternatives/f77
  /etc/alternatives/f77 -> /usr/bin/gfortran
  /usr/bin/gfortran -> gfortran-9

When compiler has errors, redirect output to file to scan

• like so: ./compile_all.csh > l1.log 2>&1

Compile has many errors re: variable named "OFF"

  987 |       CALL PVAL(N,OFF,VAL,VOFREE)
      |                  1
Error: Actual argument contains too few elements for dummy argument ‘off’ (1/20) at (1)
make: *** [<builtin>: hrintss.o] Error 1
library ../../lib/g_den_hspflib.a does not exist,

There is a Global variable called OFF with (1) dimension

C     + + + LOCAL VARIABLES + + +
      INTEGER     I,N,OFF(1),REM,WORDI,VO,SCLU,SGRP

But the subroutine it is called in does not have a dimension

CALL PVAL(N,OFF,WS,VO)
...
      SUBROUTINE PVAL
     I                (N,OFF,VAL,VO)
C
C     + + + PURPOSE + + +
C     Put one or more values into the buffer/extension and write
C     to the tss as necessary
C
C     + + + KEYWORDS + + +

(hacky) Solution is to tell compiler to ignore these problems (worked in previous version of fortran) #6

First you have to find the file that calls it

• scroll through the log file (generated by special compile redirect
• find the final "make:*** ... Error1"

Error: Actual argument contains too few elements for dummy argument ‘off’ (1/20) at (1)
make: *** [<builtin>: hrintss.o] Error 1
library ../../lib/hspflib.a does not exist,
use one of the following commands to generate it:
     make
     make all
rm -f *.o ../../lib/ICPRBhspflib.a
Removed files generated by make.

• See that the last file is ICPRBhspflib.a
  • Find it:

    fgrep ICPRBhspflib ./* -R
    > ./hspf/lib3.2/src/ICPRBhspf/makefile:library = ICPRBhspflib.a

    Then edit to add the compile option -std=legacy, by changing from: FFLAGS = -u $(OptM) to FFLAGS = -u $(OptM) -std=legacy
