我已经设置了一个mingw交叉编译器(i686-w64-mingw32)，以便在ubuntu上使用Codeblocks IDE编译windows .exe。我的"hello world"测试表明这是有效的。我现在正试图交叉编译我的完整应用程序，静态链接到一些SDL2库。我正面对着这样的错误列表:

我做了一些研究，从我收集到的，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附带解决这些问题的资源，但我无法弄清楚这些资源是什么或在哪里。虽然有些资源似乎可以解决这个问题，但我永远无法完全了解解决方案到底是什么。以下是我在stackoverflow上找到的一小部分我认为相关的资源:
在使用SDL 2和-static编译时接收对各种Windows库的未定义引用?wxWidgets如何使用代码块从linux交叉编译windows应用程序?在Linux for Windows下与mingw32交叉编译时链接libcurl
第一个链接列出了SDL2想要链接到的.dll。然而，解决方案并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，我天真地试图把它们放在我的项目文件夹中并动态链接它们，但是ubuntu不识别。dll。
第二个链接是关于使用Codeblocks IDE从ubuntu为windows交叉编译wxWidgets应用程序。我对解中的几行特别感兴趣。他们考虑设置编译器。
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。我没有在这两个"其他选项"部分。显然，特定的文件路径/文件名与wxWidgets特别相关，但是我想知道我是否需要为我的SDL2库找到一些类似的文件?我检查了一下文件系统，没有找到。
第三个链接讨论链接到.dll，首先在mingw中交叉编译它。我不理解那里的所有指令，也许是因为我的生活被IDE糖化了，从来没有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。
任何帮助将非常感激!
Pete。好的，所以我今天成功地从Ubuntu交叉编译了我的SDL2依赖于Windows的应用程序。
我的第一个错误是试图静态链接到SDL2 windows库(.lib)。我需要做的是链接到。dll。用于编译的文件。它们随SDL2一起提供在mingw文件夹中。这些文件夹是:
i686-w64-mingw32用于32位库X86_64-w64-mingw32用于64位库
在我真正使它工作之前，我遇到了许多其他的错误。我已经在另一篇文章中列出了解决这些问题的步骤:
