Question

我正在修改SDL2中的Wolfenstein 3D引擎（使用Wolf4SDL作为基础）并且我遇到了一个问题 - 当在链接器选项中使用-static时，我得到一个大的对各种事物的各种未定义的引用。这是我的构建日志，以显示我的意思：

当链接普通的Wolf4SDL mod（使用SDL 1.2）时，这种情况不会发生，如果我不使用-static，它会正确链接，但在没有其他各种DLL存在的情况下运行（即libgcc_s_dw2-1.dll等）。虽然我可以更改PATH以包含我的MinGW目录，但是当分发它时，我不能指望每个人都安装了MinGW，并且我想保留我用我的mod分发的DLL的数量。至少考虑到我已经使用了SDL_mixer和SDL_image，它已经有大量的DLL了。任何人都有解决方案吗？

Answer 1

好的，修复了问题 - 我需要链接各种Windows库，即Ole32，Oleaut32，Imm32，Winmm和Version。不确定为什么SDL 1的情况并非如此;迁移指南中没有提到它，所以我不确定差异来自何处。

Answer 2

对我而言，这意味着＆＃34;使用pkg-config --static＆＃34;因为我编译了一个静态版本，并希望使用它。

猜猜pkg-config是如何滚动的。另一种选择（如提到的OP）是要么添加你需要的库和＃34;带外＆＃34;或修改sdl2.pc，使其包含＆＃34;您需要的所有库＆＃34;在Libs：line（不是Libs.static：可能已经拥有它们的行）。

再次，pkg-config如何滚动：|

在使用SDL 2和-static进行编译时，接收对各种Windows库的未定义引用？
