我正在检查创建使用OpenGL代码的windows应用程序的不同变体。我特别感兴趣的是OpenGL核心配置文件(所谓的“现代OpenGL")。我使用代码：：块作为我的IDE。

首先，我编写了一个简单的WinAPI应用程序。它运行得很好，直到我尝试运行一些核心代码。这向我展示了如果我想在Windows中使用现代OpenGL，WinAPI在这里是没用的，因为它是用即时模式修复的。

因此，我的下一步是使用GLFW +GLFW(它是在https://glad.dav1d.de/站点上生成的)创建一个项目。在这种方法中，OpenGL函数有一些未解决的符号，但是很高兴修复了这个问题，我的项目完成了。编译和运行，没有问题。

这一次我想测试SDL变体。我下载了SDL2头和库，并将它们放在C::B安装中的正确文件夹中。一开始，我编写了一个简单的SDL2专用应用程序，它运行得很好，它向我展示了构建选项中包含和链接库不会让编译器阻塞我的代码。

现在我添加了一些代码，它使用opengl的核心功能。一开始，编译该代码会导致编译器抱怨这些函数。我通过再次添加高兴来解决这些问题，就像我以前的项目一样，它运行得很好，但只是编译。当试图链接我的程序时，编译器会弹出大量的错误：

我很确定我搞砸了链接库的东西。也许他们的顺序不对。也许我错过了一些。或可能是另一个错误。

链接器选项中的库列表是：

我不知道从什么图书馆是"__imp_SetupDiGetClassDevsA“和它的公司，因此我不知道如何做☹。

好吧，我找到问题所在了。我发现其他一些人在互联网的不同部分问了一个类似的问题，所以我在这里发布了我自己的问题的答案，所以其他人可能会发现(我希望他们会发现这是有用的)。

这些函数来自不想静态编译的SDL2。根据这篇文章Static-linking of SDL2 libraries，“正确的方法”是从sdl2-config包附带的bin\文件夹中运行SDL2。使用--static-libs运行它应该会给我们一个链接器选项列表，这些选项将在"Build ./ linker设置/其他链接器选项“对话框中编写。在我的例子中，它是：-lmingw32 -lSDL2main -lSDL2 -mwindows -Wl,--no-undefined -Wl,--dynamicbase -Wl,--nxcompat -Wl,--high-entropy-va -lm -ldinput8 -ldxguid -ldxerr8 -luser32 -lgdi32 -lwinmm -limm32 -lole32 -loleaut32 -lshell32 -lsetupapi -lversion -luuid -static-libgcc (这是，大大，比我在问题帖子中想象的要长)。

我之前没有找到它，因为sdl2-config是一个Bash文件，代码：：Block附带的MinGW没有Bash解释器，所以我不能正常运行它。幸运的是，它是一个文本文件(而不是我第一次猜到的二进制程序)，所以我只搜索了正确的行。
