以便与Eclipse一起使用。我试图删除此链接器错误：
开始编译
SDLERROR（S）：
c：/ mingw / bin /../ lib / gcc / mingw32 / 5.3.0 /../../../../ mingw32 / bin / ld.exe：找不到-lSDL collect2.exe：错误：ld返回1退出状态 21:15:54构建完成（耗时1s.36ms）
most pertinent SO archive source I researched对我的问题似乎没有可操作的答案，尽管它有完全相同的问题/错误： 标题 - 产生相同的错误消息：
c：/ mingw / bin /../ lib / gcc / mingw32 / 4.7.0 /../../../../ mingw32 / bin / ld.exe：找不到-lSDL。
如果你点击作者“解决方案”以获得与我相同的错误，我不清楚他是如何解决的。
任何帮助？
答案 0 :(得分：0)
问题解决了，SDL2真棒。确定：
c：/ mingw / bin /../ lib / gcc / mingw32 / 4.7.0 /../../../../ mingw32 / bin / ld.exe：找不到-lSDL。
重新安装SDL2，避免SDL文件和SDL2文件之间的二进制冲突 正如keltar提到的那样解决了眼前的问题，并且构建的问题没有错误！修复括号内的问题揭露了新问题：崩溃。我把程序剥离到骨头，并得出结论，崩溃是在代码之外，因为它甚至没有代码就发生了。
要解决新问题，需要将SDL2分发文件（复制到MinGW的文件）复制并从中复制SDL2.dll [可分发的DLL] [1] ---将文件拖到调试上/或释放.exe文件所在的文件夹。（。exe + dll - ＆gt; right？）moving dll to exes。构建/运行程序 它应该工作！ 您应该看到欢迎消息！ https://www.caveofprogramming.com/c-for-complete-beginners/setting-up-sdl-windows.html
