assignment makes integer from pointer without a cast [enabled by default] *edge_type = buffer;

这个问题是一个编译错误，它表示你尝试将一个指针类型的变量赋值给一个整型的变量，而且没有进行类型转换。在 C 语言中，指针类型变量存储的是内存地址，而整型变量存储的是一个整数值。因此，将一个指针赋值给一个整型变量是不合法的。

解决这个问题的方法是，使用类型转换将指针类型转换为整型类型。例如，可以使用强制类型转换将指针类型转换为整型类型，比如：

*edge_type = (int) buffer;

但是，需要注意的是，这种类型转换可能会导致数据丢失或错误。因此，在进行类型转换时需要谨慎，确保转换后的数据类型是正确的。

assignment makes integer from pointer without a cast [enabled by default]

This warning message typically occurs when you assign a pointer to an integer variable without explicitly casting it. It is enabled by default in most compilers as a safety measure to prevent potential issues.

To resolve this warning, you can explicitly cast the pointer to the desired integer type. For example:

int* ptr = /* pointer to some memory location */;
int value = (int)ptr; // explicit casting

However, keep in mind that simply casting a pointer to an integer doesn't necessarily result in meaningful or valid data. It's important to understand the context and purpose of the assignment to ensure correct behavior in your code.

assignment makes integer from pointer without a cast

This warning message is related to C language and it usually occurs when a pointer is used in a context where an integer is expected or vice versa.

For example, consider the following code snippet:

int *ptr;
int num = ptr; // Attempting to assign a pointer to an integer

In this case, the `ptr` is a pointer to an integer, but it is being assigned to an `int` variable `num` without being dereferenced. This results in the warning "assignment makes integer from pointer without a cast".

To fix this issue, you can either dereference the pointer to get its value or cast the pointer to the desired integer type. For instance:

int *ptr;
int num = *ptr; // Dereferencing the pointer to get its value

// OR

int *ptr;
int num = (int)ptr; // Casting the pointer to an integer type

It's important to note that casting a pointer to an integer type should be done with caution as it can result in unexpected behavior if the pointer doesn't point to a valid memory location.
