问题描述
我正在对SDL2中的Wolfenstein 3D引擎进行修改(使用Wolf4SDL作为基础)，但是遇到了一个问题-在链接器选项中使用-static时，我得到了大量未定义的引用各种事物.这是我的构建日志，以显示我的意思:
I'm working on a modification of the Wolfenstein 3D engine in SDL2 (using Wolf4SDL as a base) and I've run into a problem - when using -static in the linker options, I get a large variety of undefined references to various things. Here's my build log to show what I mean:

在链接普通的Wolf4SDL mod(使用SDL 1.2)时不会发生这种情况，并且如果我不使用-static但在没有其他各种DLL存在的情况下无法运行(即libgcc_s_dw2-1)，它将正确链接.dll等).虽然我可以更改PATH以包括我的MinGW目录，但是当需要分发它时，我不能期望每个人都安装MinGW，并且我希望将通过我的mod分发的DLL的数量保持在最低限度，我已经在使用带有大量DLL的SDL_mixer和SDL_image了.有人对此有解决方案吗?
This does not happen when linking a normal Wolf4SDL mod (which uses SDL 1.2), and it links correctly if I don't use -static but then won't run without various other DLLs being present (namely libgcc_s_dw2-1.dll and the like). While I can just change PATH to include my MinGW directory, when it comes time to distribute it I can't expect everyone to have MinGW installed, and I want to keep the number of DLLs I'm distributing with my mod to a minimum considering I'm already using SDL_mixer and SDL_image which come with a ton of DLLs already. Anyone have a solution to this?
推荐答案
好，解决了这个问题-我需要链接各种Windows库，即Ole32，Oleaut32，Imm32，Winmm和Version.不确定SDL 1为何不是这种情况.迁移指南中也没有提到它，所以我不确定差异的来源.
OK, fixed the problem - I needed to link a variety of Windows libraries, namely Ole32, Oleaut32, Imm32, Winmm and Version. Not sure why this wasn't the case for SDL 1; it wasn't mentioned in the Migration Guide either so I'm not sure where the difference comes from.
