多重定义…c++vsCode[重复]

我需要更改Vs代码中的某些内容吗?

这些是问题:

Build finished with error(s).

 *  The terminal process terminated with exit code: -1. 
 *  Terminal will be reused by tasks, press any key to close it. 

我在Linux中使用最新的Vs代码。我今天又安装了一次。我认为问题在于链接错误。

这是我的Snake.cpp:

#include <iostream>
#include <ncurses.h>
#include <unistd.h>
#include "Snake.h"

// Setup
void initTerminal() {
}

void initSnake() {
}

// Draw
void drawPixel(int y, int x) {

}

void drawBorder() {
  // PRINT MAP
}

void drawSnake() {
}

// Logic
bool collidesWithBorder() {

}

bool collidesWithSelf() {  
}

void moveSnake() {
}

bool handleKey(int key) {
}

我的snakeMain.cpp:

#include <iostream>
#include <ncurses.h>
#include <unistd.h>
#include "Snake.h"

int main() {
//-----here is only code and no #includes------/
return 0;
}

my tasks.json:

同样,如果我在控制台中启动游戏并用makefile编译它,那么游戏就可以运行了。但是在Vs代码中,我遇到了如上所述的问题。

谢谢大家抽出时间。
