Installing "communications" on octave 10, I see:

g++ -std=gnu++17 -c  -fPIC -I/usr/local/include/octave-10.0.0/octave/.. -I/usr/local/include/octave-10.0.0/octave -I/usr/local/include  -pthread -fopenmp -ggdb3 -O2 -march=native -mtune=native -mavx -mavx2 -flto=auto    -DGALOIS_DISP_PRIVATES -DHAVE_CONFIG_H syndtable.cc -o /tmp/oct-dQTWRw.o
ov-galois.cc: In member function ‘octave_value_list octave_galois::dotref(const octave_value_list&)’:
ov-galois.cc:97:3: error: ‘assert’ was not declared in this scope
   97 |   assert (idx.length () == 1);
      |   ^~~~~~
ov-galois.cc:54:1: note: ‘assert’ is defined in header ‘<cassert>’; did you forget to ‘#include <cassert>’?
   53 | #include "ov-galois.h"
  +++ |+#include <cassert>
   54 |

In octave 10.x #include <cassert> was removed from octave's header files. So if external code requires <cassert> it needs to include it explicitly.
