Hi Tom,

On a system without ncurses installed, I get:

$ make
  CXX    python/py-tui.o
In file included from /home/smarchi/src/binutils-gdb/gdb/python/py-tui.c:24:
/home/smarchi/src/binutils-gdb/gdb/gdb_curses.h:47:10: fatal error: ncurses.h: No such file or directory
   47 | #include <ncurses.h>
      |          ^~~~~~~~~~~

So I suspect weare missing an #if/#ifdef somwhere.  config.log contains:

/* Define to 1 if you have the <ncursesw/ncurses.h> header file. */
/* #undef HAVE_NCURSESW_NCURSES_H */

/* Define to 1 if you have the <ncurses.h> header file. */
/* #undef HAVE_NCURSES_H */

/* Define to 1 if you have the <ncurses/ncurses.h> header file. */
/* #undef HAVE_NCURSES_NCURSES_H */
