【问题描述】：
我已经设置了一个 mingw 交叉编译器 (i686-w64-mingw32) 来使用 Codeblocks IDE 在 ubuntu 上编译一个 windows .exe。我的“hello world”测试表明这是有效的。我现在正在尝试交叉编译我的完整应用程序，该应用程序静态链接到许多 SDL2 库。我正面临以下错误列表：

我做了一些研究，据我所知，这是因为 SDL2 想要动态链接到一些 windows 系统库。我还收集到 mingw 或 SDL2 都带有解决这些问题的资源，但我不知道这些是什么或在哪里。虽然一些资源似乎解决了这个问题，但我永远无法完全理解解决方案的实际情况。以下是我在 stackoverflow 上找到的一些我认为相关的资源：
Receiving undefined references to various Windows libraries when compiling with SDL 2 and -static? wxWidgets how to cross compile an application for windows from linux using codeblocks? Linking libcurl while cross compiling with mingw32 under Linux for Windows
第一个链接列出了 SDL2 想要链接到的 .dll。但是，该解决方案没有提到如何链接到它们。我在我的 Windows 机器上找到了所有这些库，我天真地尝试将它们放在我的项目文件夹中并动态链接它们，但是 ubuntu 无法识别 .dll。
第二个链接是关于使用 Codeblocks IDE 从 ubuntu 交叉编译 Windows 的 wxWidgets 应用程序。解决方案中的几行特别让我感兴趣。他们关于设置编译器。
Compiler Settings > Other Options : `/usr/local/i586-mingw32/bin/wx-config --cxxflags`
Linker Settings > Other Options : `/usr/local/i586-mingw32/bin/wx-config --libs`
这是解决方案的编译器设置中唯一与我自己的编译器设置不同的部分。我在这些“其他选项”部分中没有任何内容。显然，特定的文件路径/文件名与 wxWidgets 相关，但我想知道是否需要为我的 SDL2 库找到一些类似的文件？我对文件系统进行了侦察，但没有运气。
第三个链接讨论了链接到 .dll，首先在 mingw 中交叉编译它。我不明白那里的所有说明，也许是因为我的生活被 IDE 涂上了糖衣，并且从未处理过编译程序的细节，无论如何，我相当确定这个资源是相关的。
任何帮助将不胜感激！
皮特。
