GLFW将无法正确链接 [英] GLFW Won't Link Correctly

问题描述

所以最近我开始了一个涉及GLFW的项目（64位，带有GLEW）。但是，我似乎无法使其正确链接。以下是我的设置：

操作系统：Windows 8 64位

编译器：mingw64

p>

IDE：eclipse

我的简单测试程序：

  #include< stdio.h> 
 #include< stdlib.h> 
 
 #define GLEW_STATIC 
 #include< gl / glew.h> 
 #include< gl / glfw3.h> 
 
 int main（void）{
 glfwInit（）; 
 puts（Hello，World！）; 
 return（EXIT_SUCCESS）; 
}

这些错误（注意这些只在引用任何GLFW函数时才会发生，它们不会通过简单包含头部而发生）：

解决方案

您的静态GLFW库使用 _ GLFW_NO_DLOAD_WINMM 编译时宏启用。这个和其他这样的宏可以在GLFW配置头文件中找到。

定义这个会导致GLFW假定你将链接到winmm（ winmm .lib 在Visual C ++上或 libwinmm.a 在MinGW上）。这不是库的静态版本的默认设置，所以我假设你自己编译了它。您可以将winmm添加到链接时依赖项，或者在编译GLFW时不定义 _GLFW_NO_DLOAD_WINMM 。

让你的程序链接。

So recently I've started a project involving GLFW (64-bit, with GLEW). However, I can't seem to get it to link correctly. Here's how I'm set up:

OS: Windows 8 64-bit

Compiler: mingw64

IDE: eclipse

My simple test program:

#include <stdio.h>
#include <stdlib.h>

#define GLEW_STATIC
#include <gl/glew.h>
#include <gl/glfw3.h>

int main(void) {
    glfwInit();
puts("Hello, World!");
    return (EXIT_SUCCESS);
}

How I've set up the linking: http://i.imgur.com/yyISNtZ.png

The errors (note these only occur when referencing any GLFW function. They don't occur by simply including the header):

解决方案

Your static GLFW library is compiled with the _GLFW_NO_DLOAD_WINMM compile-time macro enabled. This and other such macros may be found in the GLFW config header.

Defining this causes GLFW to assume that you will be linking against winmm (winmm.lib on Visual C++ or libwinmm.a on MinGW). This is not the default setting for the static version of the library, so I assume you have compiled it yourself. You can either add winmm to your link-time dependencies or not define _GLFW_NO_DLOAD_WINMM when compiling GLFW.

Either solution should make your program link.
