Question

我做错了什么？奇怪，因为构造函数的签名是相同的。编译器说：＆＃39; ShaderProgram :: ShaderProgram（std :: vector＆lt; int *，std :: allocator＆lt; _Ty＆gt;＆gt;）＆＃39;：在＃ShaderProgram＆＃39;中找不到重载的成员函数。当我使用带有代码的3个文件（下面）时，会发生此错误，但是当我将此代码放在1个文件（主要cpp）中时 - 它可以正常工作

//main.cpp
#include <stdlib.h>
#include <stdio.h>
#include <vector>
#include "ShaderHelpers.h"


int main(int argc, const char* argv[]) {

    int* a = new int(5);
    int* b = new int(7);
    ShaderProgram *sp = new ShaderProgram(std::vector<int*>{ a, b}); 
    return 0;
}
================================================================
//shader.cpp
#include "ShaderHelpers.h" 
#include <iostream>
#include <stdlib.h>
#include <stdio.h>
#include <vector> 
#include <string>

ShaderProgram::ShaderProgram() { }

ShaderProgram::ShaderProgram(std::vector<int*> shaders)
{
    Shaders = shaders;  
    for each (int* i in shaders)
    {
        std::cout << i;
    }
}

ShaderProgram::~ShaderProgram()
{
    std::cout << "delete";
}


===============================================================
//ShaderHelper.h
#pragma once    
#include <string>


class ShaderProgram
{
public:
    std::vector<int*> Shaders;
    ShaderProgram(std::vector<int*> shaders); 
    ~ShaderProgram();

private:
    ShaderProgram();

};

Answer 1

我只需要添加

# include <vector>

进入ShaderHelper.h

＆＃39; ShaderProgram中找不到c ++重载的成员函数
