glfw3编译未定义的引用 [英] glfw3 compiling undefined references
问题描述
我有一个编译我的程序使用glfw3库的问题。
I have a problem with compiling my program which uses glfw3 library.
我得到未定义的引用的错误列表当尝试编译与make但我的类。
stdout：
I'm getting list of errors of undefined references when trying to compile with make but my classes are compiled into .o files, only final executable file is not created.
stdout:stderr：
stderr:这是我的makefile：

this is my makefile:

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

sWindow.o: sWindow.cpp

clean:
rm -f *.o main
echo "Clean done"
推荐答案
按照以下顺序执行：
-lglfw3 -lGLU -lGL
而不是这一个：
-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 ，那么你必须在下面调用linker方式：
GCC is very sensitive to the order in which you specify libraries during the linking stage. For example, if libA.a depends on libB.a, then you'd have to invoke linker in the following way:
gcc ... -lA -lB ...
在你的情况下， libglfw3.a 显然取决于 libGL.a ，因此您得到的错误。
In your case, libglfw3.a obviously depends on libGL.a, hence the errors you are getting.
