A warning and an error message .

まず optimi.F の 7593 行付近と dp1.F の 3108～3111 行付近を確認し、次に報告された make コマンドを実行して警告とエラーを再現します。ビルドが報告された type-mismatch 警告または unterminated character-constant エラーなしで完了すれば完了です。

During making DataPlot today ,
the following warning has been issued :

( 1 )

gfortran -O2 -DLINUX -fdefault-real-8 -fdefault-double-8 -c -o optimi.o optimi.F
optimi.F:9767:72:

  $                  XPLUS ,FVECEV)
                                                                    1

Warning: Type mismatch in argument ‘acpcod’ at (1); passed INTEGER(4) to REAL(8) [-Wargument-mismatch]

I have removed this warning by including 'acpcod" into INTEGER statement of

SUBROUTINE LINE( ...

in line 7593 .

(2)

gfortran -O2 -DLINUX -fdefault-real-8 -fdefault-double-8 -DDDOUBLE -DINTEGER32 -DHAVE_ISNAN -DHAVE_EXECUTE_COMMAND_LINE -DDPLIBDIR='/Packages/Statistics_in_Fortran/github.com_usnistgov_dataplot_PD/2020_04_25/dataplot-master/src/../Installed/lib/dataplot' -c -o dp1.o dp1.F
dp1.F:3111:18:

       UNIXPN=STRZZZ(DPLIBDIR)
              1

Error: Unterminated character constant beginning at (1)
make: [Makefile💯 dp1.o] Error 1 (ignored)

I have corrected that error message by modifying the line 3108 of DP1.F file as follows :

#define STRZZZ(x) 'x'

Then "make" has been completed successfully and it installed the programs into supplied local directory with inner directories resembling root directories for an install .

Thank you very much .
