#9 Fails to build with GCC/ gfortran 8: "Error: Actual argument contains too few elements for dummy argument ‘angle’ (3/4) at (1)".

[Drei Eck]

Recently, building the latest auto-07p (Version 0.9.1 from https://sourceforge.net/projects/auto-07p/files/auto07p/0.9/auto07p-0.9.1.tar.gz/download) fails with up to date gcc compiler.

The error message is:

gfortran -O3 -c  plautlib.f -o plautlib.o
plautlib.f:6777:48:

           CALL ARROWL(I,XC(I,2),YC(I,2),ALFA,DA,ANGLE,XC,YC,ICODE)
                                                1
Error: Actual argument contains too few elements for dummy argument ‘angle’ (3/4) at (1)
make[1]: *** [Makefile:14: plautlib.o] Error 1

gfortran version is: GNU Fortran (GCC) 8.2.1 20180831

With gcc 7 it still worked.

This bug has also been reported to Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=897711.

Whereas I do not build on debian but use your sources directly and build on Arch/ Artix Linux using the recipe at https://aur.archlinux.org/packages/auto-07p/ (I maintain this AUR package, btw.).

As a temporary workaround, -std=legacy can be added to the compiler flags, e.g. in the FFLAGS variable in the Makefile of plaut (07p/plaut/Makefile.in). This changes the error message into a warning, the same way as older version of gfortran behaved.

I'm having the very same problem. I'm trying to install in Manjaro 18.0.2 and can't have a succesfull instalation. I have tried the solution of Carsten Bruns but the result is a corrupted instalation that does't work. Any news?

[Drei Eck]

Using the old g95-compiler seems to be a workaround, but not a proper solution, though.

I fixed it here:
https://github.com/auto-07p/auto-07p/commit/4d22983d627762fc2d6e763796668e6ea4f7a783
just replace ANGLE(3) with ANGLE(4) and it will compile.
