C++ 我的OPENGL GLFW窗口没有随时间更新颜色

我正在关注openGL超级圣经第七版

在我正在查看的项目中，应该在创建的窗口中创建随时间变化的背景色。我使用的所有项目和设置的源文件都可以在上找到。我正在Visual Studio 2017的发行版上运行它

下面是输出窗口的输出：

我知道在输出中打印符号不是很必要，因为它们主要用于调试DLL中是否存在错误。但我觉得问题的根源在于这一行： 'singlepoint.exe'（Win32）：加载了'C:\Windows\System32\DriverStore\FileRepository\nvhm.inf\u amd64\u ebea877f10dfbbc7\nvinit.dll'。找不到或无法打开PDB文件。 我可能完全错了，但这是我目前唯一看不到的地方

您已将

颜色

标记为

静态

。这意味着它只会在第一次调用此函数时收到一个值，并且不会再次更新（因为它被标记为

const

，所以在初始化后，如果不依赖于未定义的行为，它将无法更改）。删除

static

关键字，此函数的行为应该与您期望的方式相同

---

此外，“无法找到或打开PDB文件”错误与此无关，与您的问题无关。这样做的唯一结果是，在调试器中单步执行某些函数更加困难

在a中编辑。我做了一次编辑，将其简化为随时间变化的颜色。我知道我应该工作，因为它写在超级圣经书上。希望这对每个人都足够了。如果不让我知道我需要做什么来修复它，我会的。“我知道它应该有效，因为它写在圣经里。”。先生，你让我高兴极了。非常感谢！现在看来很明显。我以后一定要记住这一点！再次感谢！
