Question

我关注this tutorial。我完全cmake'd和make/make install'd glfw和glew（据我所知）。但是，当我尝试编译示例代码时......

#define GLEW_STATIC
#include <GL/glew.h>
#include <GLFW/glfw3.h>

int main()
{
    glfwInit();
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

    return 0;
}

...使用他的链接器标志......

-lGLEW -lglfw3 -lGL -lX11 -lpthread -lXrandr -lXi

...我收到以下错误：

/usr/bin/ld: /usr/local/lib/libglfw3.a(x11_init.c.o): undefined reference to symbol 'XF86VidModeQueryExtension'
/usr/lib/x86_64-linux-gnu/libXxf86vm.so.1: error adding symbols: DSO missing from command line

我谷歌发现错误，有人建议添加-lXxf86vm。它摆脱了最初的错误，但又增加了很多：

/usr/local/lib/libglfw3.a(x11_init.c.o): In function `initExtensions':
x11_init.c:(.text+0x1b93): undefined reference to `XineramaQueryExtension'
x11_init.c:(.text+0x1bad): undefined reference to `XineramaIsActive'
/usr/local/lib/libglfw3.a(x11_init.c.o): In function `_glfwCreateCursor':
x11_init.c:(.text+0x22ee): undefined reference to `XcursorImageCreate'
x11_init.c:(.text+0x23c5): undefined reference to `XcursorImageLoadCursor'
x11_init.c:(.text+0x23d5): undefined reference to `XcursorImageDestroy'
/usr/local/lib/libglfw3.a(x11_monitor.c.o): In function `_glfwPlatformGetMonitors':
x11_monitor.c:(.text+0x743): undefined reference to `XineramaQueryScreens'

如何找出我需要的标志？如果重要，这就是我的makefile的结构：

CC = g++
COMPILER_FLAGS = -std=c++11
FILES = *.cpp
LINKER_FLAGS =   -lGLEW -lglfw3 -lGL -lX11 -lpthread -lXrandr -lXi -lXxf86vm
OBJS = *.o
LINUX_BIN = HelloWindow

#Compile(output into error.txt if there is an error), link, then run
linux:
    $(CC) $(COMPILER_FLAGS) -c $(FILES) 2> "errors.txt"
    $(CC) $(COMPILER_FLAGS) $(OBJS) -o $(LINUX_BIN) $(LINKER_FLAGS)
    ./$(LINUX_BIN)

谢谢！

Derhass是对的。以下是我使用的标志：

-lGLEW -lglfw3 -lGL -lX11 -lXi -lXrandr -lXxf86vm -lXinerama -lXcursor -lrt -lm -pthread

未定义的引用在Ubuntu上编译OpenGL / glfw / glew（g ++）
