作为IDE，我使用代码块。当我在IDE上编译和运行程序时，工作正常。同样，当我在命令行中编译和运行程序时，工作正常：

g++ main.cpp -o output.exe -I"C:\Program Files\mingw-w64\mingw64\include" -lglu32 -lopengl32 -lfreeglut

唯一的问题是，当我使用gnu命令

make

时。当我在

cmd

中执行

make test

时，我得到以下错误：

g++-c-o main.o main.cpp main.cpp:5:10:致命错误：GL/glut.h:否这样的文件或目录#include//GLUT，include glu.h 和gl.h ^~~~~~~~~~~~~~编译已终止。make:**[：main.o]错误1

库和路径是否在

makefile

中定义得不好？我无法完全理解为什么

make

不起作用

谢谢。

您定义了一条规则

.cc.o

，该规则使用您自己的变量名定义编译。但是，您的文件名为name

main.cpp

，因此将使用默认规则：

.cpp.o:
    $(COMPILE.cpp) $(OUTPUT_OPTION) $<

因此，要么将

main.cpp

的文件名更改为

main.cc

，

COMPILE.cpp

的定义，要么更改

.cpp.o

目标的定义。或者，您可以将您的标志添加到默认变量名并删除.cc.o规则。

您没有为GL添加包含路径。GL/glut.h的路径是什么？C:\Program Files\mingw-w64\mingw64\include\GLI在makefile中找不到此行

g++-C-o main.o main.cpp

？您确定使用了正确的Makefile吗？应该是：

$（程序）：$（对象）$（源）$（编译器）$（编译器框架）-o$（程序）$（对象）$（库）

，对吗？此行的输出应该是

g++--std=c++17-无饼图-I“c:\PROGRAM Files\mingw-w64\mingw64\include”-o test-L“c:\PROGRAM Files\mingw-w64\mingw64\lib”-lGL-lGLU-lglut-lm-lXi-lXmu-lglu32-lopengl32-lfreeglut

。但是实际输出是

g++-c-omain.omain.cpp

。当前您正在使用不同的makefile。给定的生成文件无法生成错误消息。Makefile必须使用大写字母

准确命名为

Makefile

。或者您必须调用

make-f makefile
