C++ glfw3编译未定义的引用

我在编译使用glfw3库的程序时遇到问题

当我试图用make编译时，我得到了未定义引用的错误列表，但是我的类被编译成了.o文件，只有最终的可执行文件没有被创建

标准：

g++ -Wall -g -c main.cpp -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi 

g++ -Wall -g -c error.cpp -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi

g++ -Wall -g -c sWindow.cpp -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi 

g++ -Wall -g -o ecl main.o error.o sWindow.o -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi

这是我的生成文件：

CXX = g++
CXXFLAGS = -Wall -g
LIBS = -lGL -lGLU -lglfw3 -lX11 -lXxf86vm -lXrandr -lpthread -lXi
DEPENDENCIES = main.o error.o sWindow.o

# ****************************************************
# Targets needed to bring the executable up to date

ecl: $(DEPENDENCIES)
    $(CXX) $(CXXFLAGS) -o ecl $(DEPENDENCIES) $(LIBS)

main.o: main.cpp
    $(CXX) $(CXXFLAGS) -c main.cpp $(LIBS)

error.o: error.cpp
    $(CXX) $(CXXFLAGS) -c error.cpp $(LIBS)

sWindow.o: sWindow.cpp
    $(CXX) $(CXXFLAGS) -c sWindow.cpp $(LIBS) 

clean: 
    rm -f *.o main
    echo "Clean done"

你知道是什么原因造成的，以及如何修复它吗？

按以下顺序操作：

-lglfw3 -lGLU -lGL

而不是这个：

-lGL -lGLU -lglfw3

GCC对在链接阶段指定库的顺序非常敏感。例如，如果

libA.a

依赖于

libB.a

，则必须以以下方式调用链接器：

gcc ... -lA -lB ...

---

在您的情况下，

libglfw3.a

显然依赖于

libGL.a

，因此您会得到错误。

不确切知道，但对我来说，

-lglfw

起作用，而不是

-lglfw3
