在 Windows 上的 Code::Blocks 中编译 SDL2 + OpenGL + GLAD 项目：未定义的引用
Compiling SDL2 + OpenGL + GLAD project in Code::Blocks on Windows: undefined references
我正在检查创建使用 OpenGL 代码的 windows 应用程序的不同变体。我对 OpenGL Core Profile（所谓的 "modern OpenGL"）特别感兴趣。我正在使用 Code::Blocks 作为我的 IDE。
起初我编写了一个简单的 WinAPI 应用程序。它运行良好，直到我尝试 运行 一些核心代码。这告诉我，如果我想在 Windows 中使用现代 OpenGL，WinAPI 在这里没有用，因为它已在立即模式下修复。
因此，我的下一步是使用 GLFW + GLAD（在 https://glad.dav1d.de/ 网站上生成）制作一个项目。在这种方法中，OpenGL 函数有一些未解析的符号，但 GLAD 解决了这个问题，我的项目就完成了。编译 & 运行 没有问题。
这次我想测试一个SDL变体。我下载了 SDL2 头文件和库，并将它们放入 C::B 安装中的正确文件夹中。起初我编写了一个简单的仅 SDL2 应用程序并且它运行良好，这向我展示了在构建选项中包含和 links 到库不会让编译器阻塞我的代码。
现在我添加了一些使用opengl核心功能的代码。起初编译该代码导致编译器抱怨这些函数。我通过再次添加 GLAD 解决了这些问题，就像我以前的项目一样，它工作正常，但只是编译。当尝试 link 我的程序时，编译器吐出了很多这样的错误：

我很确定我在 linking 库中搞砸了一些东西。也许他们的顺序错误。也许我想念一些。 或 可能是另一个错误进入。
我在 link 层选项中的图书馆列表是：
mingw32
SDL2main
SDL2
glew32
opengl32
glu32
我不知道“__imp_SetupDiGetClassDevsA”和它的公司来自哪个图书馆，因此我不知道该怎么做☹。
好的，我找到问题所在了。我发现其他人在 Internet 的不同部分问了类似的问题，所以我 post 在这里回答我自己的问题，这样其他人可能会找到它（我希望他们会觉得这很有用）。
这些函数来自不想静态编译的SDL2。
根据此 post Static-linking of SDL2 libraries "proper way" 是 运行 sdl2-config 从 bin\ 文件夹随 SDL2 包一起提供。 运行 它与 --static-libs 应该给我们一个链接器选项列表，以便在 "Build Options... / Linker settings / Other linker options" 对话框中写入。在我的例子中是：
-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（这个列表 比我在问题 post 中想的要长）。
我没有早点找到它，因为 sdl2-config 是一个 Bash 文件，而 Code::Blocks 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（而不是我最初猜测的二进制程序），所以我只是在其中搜索了正确的行。
我正在检查创建使用 OpenGL 代码的 windows 应用程序的不同变体。我对 OpenGL Core Profile（所谓的 "modern OpenGL"）特别感兴趣。我正在使用 Code::Blocks 作为我的 IDE。

我很确定我在 linking 库中搞砸了一些东西。也许他们的顺序错误。也许我想念一些。 或 可能是另一个错误进入。
我在 link 层选项中的图书馆列表是：
mingw32
SDL2main
SDL2
glew32
opengl32
glu32
我不知道“__imp_SetupDiGetClassDevsA”和它的公司来自哪个图书馆，因此我不知道该怎么做☹。
好的，我找到问题所在了。我发现其他人在 Internet 的不同部分问了类似的问题，所以我 post 在这里回答我自己的问题，这样其他人可能会找到它（我希望他们会觉得这很有用）。
这些函数来自不想静态编译的SDL2。
根据此 post Static-linking of SDL2 libraries "proper way" 是 运行 sdl2-config 从 bin\ 文件夹随 SDL2 包一起提供。 运行 它与 --static-libs 应该给我们一个链接器选项列表，以便在 "Build Options... / Linker settings / Other linker options" 对话框中写入。在我的例子中是：
-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（这个列表 比我在问题 post 中想的要长）。
我没有早点找到它，因为 sdl2-config 是一个 Bash 文件，而 Code::Blocks 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（而不是我最初猜测的二进制程序），所以我只是在其中搜索了正确的行。
