构建 shared_ptr 时遇到问题 [英] Trouble constructing shared_ptr

问题描述

我是智能指针的新手，我正在努力解决每一个绊脚石.

I'm new to smart pointers, and I'm in the process of hitting every stumbling block.

我有一个结构texture_t:

struct texture_t
{
    hash32_t hash;
    uint32_t width;
    uint32_t height;
    uint32_t handle;
};

当我尝试使用此行创建此结构的 shared_ptr 时:

When I try and make a shared_ptr of this struct using this line:

auto texture_shared_ptr = std::make_shared<texture_t>(new texture_t());

我收到此错误:

error C2664: 'mandala::texture_t::texture_t(const mandala::texture_t &)' : cannot convert parameter 1 from 'mandala::texture_t *' to 'const mandala::texture_t &'

这个错误来自哪里，我该如何避免?

Where is this error coming from and how can I avoid it?

推荐答案

您不应该将 new ed 指针传递给 std::make_shared.您只需要传递可以构造 texture_t 的参数.

You are not supposed to pass a newed pointer to std::make_shared. You just need to pass arguments from which a texture_t can be constructed to it.
