我在C ++中有一个带有头文件的源文件
#include<graphics.h>
图形库似乎不在include文件夹中，我从互联网上下载并将graphics和winbgim头文件复制到{{1} }文件夹include进入libbgi.a文件夹，然而，当我来运行源文件时，我会收到大量错误。
这是源文件;
lib运行时，此文件出现
# include <iostream>

设置Project Options - ＆gt; Parameters - ＆gt; Linker为

-luuid

-lole32
答案 1 :(得分：0)
您正在使用file，而不是project
首先下载graphics.h并将此标题添加到C:\Dev-Cpp\include
第二次下载Libraries，提取文件并将文件放到C:\Dev-Cpp\lib
现在，打开Dev C ++，在File菜单中选择new＆amp;新项目 粘贴代码并转到链接器参数的项目选项
lbgi
lgdi32
lcomdlg32
luuid
loleaut32
lole32
我建议您使用Visual Studio and the same library进行图形编程
另请参阅this page以获取有关graphics.h
答案 2 :(得分：0)
我无法发表评论，因为我没有足够的声誉，我不得不留下答案，即使可能没有人需要这个。
其他答案都是正确的，但我看到没有解决我遇到graphics.h遇到的一个问题：它在第302行有一个错误（在我的版本中，似乎与你的相同） ）在以下声明中：
void printimage(
...
int left=0, int right=0, int right=INT_MAX, int bottom=INT_MAX,
...
);
为清楚起见，我只留下了错误。请参阅：int right=0, int right=INT_MAX？重新定义。您可以在帖子中搜索它，然后就可以找到它。
实际应该是：
void printimage(
...
int left=0, int top=0, int right=INT_MAX, int bottom=INT_MAX,
...
);
