错误 LNK2038：检测到“_ITERATOR_DEBUG_LEVEL”不匹配：值“2”与 XX.obj 中的值“0”不匹配

Question

我对 c++ 非常陌生，并且在尝试构建我的 c++ OpenGL 项目的发布版本时遇到此错误。经过一番谷歌搜索后，我将 C/C++ > 代码生成 菜单中的运行时库更改为 Multi-Threaded Debug GLL (/MDd)，然后解决了问题.我想知道这样做是否正确。

我新建了一个空项目作为测试，Release模式下默认的Runtime Library设置是Multi-Threaded (/MD)。调试模式的默认运行时库是多线程调试 (/MDd)。尽管有不同的运行时库，但两个配置都成功构建，这让我想知道我的项目设置是否在某个时候出现了混乱。

另一个让我好奇的细节是尝试在 Release x64 中构建时的输出日志：

我突出显示了中间文件路径从 bin\x64\Release 更改为 bin\intermediates\Win32\Debug 的两行，我想知道这是否有助于解决这个问题。

虽然不是一个完美的解决方案，但我最终创建了一个新项目并一个接一个地重新导入所有依赖项，在两者之间进行编译以尝试查找问题。导入所有库后，新项目就可以工作了。然后我复制了我所有的代码并在新的解决方案中编译它，它有效，所以问题已经解决了。

我在两个项目文件之间保存了diff，但找不到问题（它们太不同了，我无法理解）。也许有更多经验的人可以弄清楚。
