It can run in VS2019, but when called in QT (5.14.1), enet_host_create cannot produce a server. This is my code.

    if (enet_initialize() != 0) {
        printf("An error occurred while initializing ENet.\n");
    }

    ENetAddress address = { 0 };

    //address.host = ENET_HOST_ANY; /* Bind the server to the default localhost.     */
    enet_address_set_host(&address, "127.0.0.1");
    address.port = 7777; /* Bind the server to port 7777. */

#define MAX_CLIENTS 32

/* create a server */
    ENetHost* server = enet_host_create(&address, MAX_CLIENTS, 2, 0, 0);

    if (server == NULL) {
        printf("An error occurred while trying to create an ENet server host.\n");
        return 1;
    } else {
        printf("Started a server...\n");
    }

Why is sever null? I've tried two compiler methods of MSVC2015_64bit-Debug and MinGW_32_bit-Debug.

I traced the code bind(socket, (struct sockaddr *)&sin, sizeof(struct sockaddr_in6)) and found the error code to be 10049 by WSAGetLastError().

How to fix this in QT？

I tested the release mode and found that it works, but the debug mode does not.(MSVC2015_64bit) Do you have any solution？
