Curses problem: initscr and endwin missing

[hsmyers]

Having successfuly installed Curses and Curses::GUI, I wrote the following test code;

#!/usr/bin/perl
# test.pl -- 
use Modern::Perl '2020';
use utf8;
no if $] >= 5.018, warnings => "experimental";
use open ':std', ':encoding(UTF-8)';
use autodie;
use Curses;

initscr;
endwin;

That produces the following error message;

C:\Users\hsmyers\perl\two>test
Curses function 'initscr' is not defined in your Curses library at C:\
+Users\hsmyers\perl\two\test.pl line 10.

if you comment out initscr; you get an nearly identical message;

C:\Users\hsmyers\perl\two>test
Curses function 'endwin' is not defined in your Curses library at C:\U
+sers\hsmyers\perl\two\test.pl line 11.

Just as a check I compiled the following with;

gcc curhello.c -lcurses

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <curses.h>

int main(void) {
    WINDOW * mainwin;

    if ( (mainwin = initscr()) == NULL ) {
    fprintf(stderr, "Error initialising ncurses.\n");
    exit(EXIT_FAILURE);
    }
    mvaddstr(13, 33, "Hello, world!");
    refresh();
    sleep(3);
    delwin(mainwin);
    endwin();
    refresh();

    return EXIT_SUCCESS;
}

As I thought, it ran without a problem. This, in my mind, suggests that the successful installation of curses.pm, wasn't. All of this is in Windows 10, the most problematic perl playground. Since I've already done a great deal of coding using WSL/Ubuntu, I know that the same module has no problem in 'nix, just Windows. Does anyone have any suggestions?

I once built the Curses distribution on Windows with PDCurses. I can't recover the details (the machine has been long retired), but it wasn't much harder than specifying the correct locations for the headers and the import library. The result was nice: I was able to run some Perl scripts with Curses, they seemed to behave well.

My current plan A is to roll up my sleeves and tear apart the cpan Curses.pm module and see what makes it tick. I'm hoping for here is a plan B or C. I'm using PDCurses with a copied and renamed lib to libcurses. It makes compiling easier.

Does it tell you anything useful if you run Makefile.PL with environment variable CURSES_VERBOSE set to a truthy value? It seems that all tests for existence of Curses functions somehow managed to fail.
