Confirmed on Debian, installation succeeds and it's probably doing the right thing, but the warning should be addressed.

Here's the warning:


>> pkg install -forge communications
gf.cc:47:9: warning: 'OCTAVE__ERR_SQUARE_MATRIX_REQUIRED' macro redefined [-Wmacro-redefined]
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")
        ^
gf.cc:43:9: note: previous definition is here
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
        ^
1 warning generated.


Here's the code:


#ifdef HAVE_OCTAVE_GRIPES_H
#include <octave/gripes.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
#endif
#ifdef HAVE_OCTAVE_ERRWARN_H
#include <octave/errwarn.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")
#endif


Maybe HAVE_OCTAVE_GRIPES_H and HAVE_OCTAVE_ERRWARN_H are not mutually exclusive, and that should be an "#else ifdef" or something there?

When installing package communications on Octave 4.4.1 on macOS 10.14, I get this warning about a redefined macro:


>> pkg install -forge communications
gf.cc:47:9: warning: 'OCTAVE__ERR_SQUARE_MATRIX_REQUIRED' macro redefined [-Wmacro-redefined]
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")
        ^
gf.cc:43:9: note: previous definition is here
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
        ^
1 warning generated.

Here's the code in gf.cc:

+verbatim+
#ifdef HAVE_OCTAVE_GRIPES_H
#include <octave/gripes.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) gripe_square_matrix_required(a)
#endif
#ifdef HAVE_OCTAVE_ERRWARN_H
#include <octave/errwarn.h>
#define OCTAVE__ERR_SQUARE_MATRIX_REQUIRED(a) err_square_matrix_required(a, "")
#endif
+verbatim+

Sounds like HAVE_OCTAVE_GRIPES_H and HAVE_OCTAVE_ERRWARN_H are not mutually exclusive? Maybe that should be an "#else ifdef HAV_OCTAVE_ERRWARN_H" in there?
