二叉树节点 - GCC警告 - 不兼容的类型

I'm trying to create a new node for a binary tree, and I'm getting errors when I try to make an assignment to ->left and ->right.

我正在尝试为二叉树创建一个新节点,当我尝试将任务分配给 - > left和 - >时,我遇到了错误。

typedef struct bin_node_t {
     data_t data;
     bst_key_t key;
     struct bin_node *left;
     struct bin_node *right;
} bin_node;

Is my struct definition for bin_node.

是我对bin_node的结构定义。

Here are the variables I'm using:

以下是我正在使用的变量:

bin_node *new;
bin_node *node_array[256];

Here's my variable assignments:

这是我的变量赋值:

/* ... code to initialize node_array ... */
new = (bin_node *)malloc(sizeof(bin_node));

and here's where I'm gettin an error:

而这里是我遇到错误的地方:

    new->right = node_array[i+1];
    new->left = node_array[i];

and here is the compiler warning I'm getting:

这是我得到的编译器警告:

huffman.c:99: warning: assignment from incompatible pointer type
huffman.c:100: warning: assignment from incompatible pointer type

There's no struct bin_node in your code. Change struct bin_node *left to:

您的代码中没有struct bin_node。将struct bin_node *更改为:

struct bin_node_t *left;
