(非常详细的问题报告--tl；底部的dr！)
我真的更喜欢GLFW，而不是过剩，我想让它的Golang binding在64位Windows64位和Go 1.0.1 64位下运行.在Linux下，它的绑定工作得无懈可击.原则上，这在Windows下是可行的--GitHub用户CHSC has managed到do so，但是他使用的是Win32，他的提示还没有解决我的问题.但是，我确实有一个完整而干净的基于TDM64-GCC-4.6.1的Mingw64设置.
现在奇怪的是--让freeglut绑定在64位Windows、64位Go 1.0.1 works下工作--为我编写glfw绑定fails.我想找出原因，因为他们是essentially both use the same cgo features and techniques人.
注意:我目前有一个brew 的半成品但基本上可以使用的替换包，它使用LoadLibrary/GetProcAddress调用来公开glfw.go 吧.这是可行的，但我认为在CGO绑定中编译硬链接比无数的Syscall()、Syscall6()、Syscall9()、Syscall12()等Go func调用更可取.如果Win32和Linux Gopher都能做到这一点，为什么我们不能用Win64呢？
以下是我目前的设置:
- 我有一个应用了three patches to make lib linking work with cgo的Golang版本
- 我已经使用MinGW64成功地将最新的freeglut和GLFW库编译为64位DLL.
- 头文件Glu.h、freeglut*.h和glfw.h放在\MinGW64\x86_64-w64-mingw32\include\GL中(位于gl.h、glex.h、gl.h旁边)
- LIB文件libfreeglut.a和libglfwdll.a放在\MinGW64\x86_64-w64-mingw32\lib中(紧挨着liblu32.a、libopengl32.a)
- 64位DLL glfw.dll和freeglut64.dll放在\windows和\windows\system32中(位于opengl32.dll、lu32.dll旁边)
- freeglut64.dll和glfw.我相信，dll both work——至少他们的大多数示 routine 序在安装dll后都会这样做.
一切都应该就位了，对吧？现在，首先是成功的绑定(我不需要)，freeglut--当I为go get -x github.com/zombiezen/Go-GLUT/glut时，一切都构建得很好，我可以成功地创建一个过剩窗口，并在从.go源文件编译的Windows test.exe中显示一个三角形.多亏了-x，让我们来看看它用来构建的功能:

为了达到这一点，我必须稍微修改过剩.如下所示:
// # include <GL/glut.h>
// #cgo windows LDFLAGS: -lfreeglut
// #include <stdlib.h>
// #include "support.h"
import "C"
所以，总而言之，这个构建很好，可以从Go导入和链接，并在代码中使用.
现在是GLFW的节目.GO文件读起来与GUG.GO极其相似:
//#cgo windows LDFLAGS: -lglfwdll -lglu32 -lopengl32
//#include <stdlib.h>
//#define GLFW_DLL
//#include <GL/glfw.h>
import "C"
#DEFINE GLFW_DLL为no static linking happens.不过，下面是go get -x github.com/jteeuwen/glfw的输出:

是的，这很冗长--但基本上总是相同的错误，而且在构建过程中相当晚.注意，如果没有定义#定义GLFW_DLL，我得到的输出基本上是相同的，只是没有__imp_前缀--对于Go，既不鼓励使用静电链接，也不希望在这个特定的用例中使用它.
现在，当GCC抱怨"引用不明确"时，从我在谷歌上搜索到的可能有各种原因……
- 找到DLL不会失败--它们位于适当的位置，对于freeglut64.dll，它可以工作
- 如果我把-lglfwdll改成-lblafoobar，那么GCC就会更早地失败，并正确地抱怨"blafoobar找不到"--所以它does找到了libglfwdll.a，这不可能是找不到.a库--它们在适当的位置，libfreeglut.a可以工作，如果我把-lglfwdll改成-lblafoobar，那么GCC就会更早地失败.
- 库依赖关系的顺序？我try 将-lglfwdll作为第一个库(在-llu32-lopengl32之前)和最后一个库(在这两个库之后)，没有区别.
- Golang glfw装订有问题吗？我不这么认为，它适用于其他操作系统，包括Windows for CHSC(虽然是32位)
TL；DR--在Windows64位、GO 1.0.164位完全补丁下，cgo成功生成bothfreeglut和glfw的东西给GCC.然后，GCC很高兴地吃了这个东西来构建freeglut绑定，but拒绝它来构建glfw绑定，并对所有C.funcs()"未定义的引用".libfreeglut和libglfwdll都被正确构建和安装为64位DLL和正确定位的.h/.a库.可能的原因是什么？
