c++ - 错误 LNK2038 : mismatch detected for '_ITERATOR_DEBUG_LEVEL' : value '0' doesn't match value '2' in main. 对象

Question

我已经阅读了很多关于我的问题的解决方案，但没有任何帮助。我试过干净，重建。重新安装了visual 2010并从专业更改为终极。但我仍然不知道为什么我有这个错误。我的项目如下所示:1 用于测试我的静态库的 Exe 解决方案。1 DLL解决方案静态库。转换为 dll 的代码正在使用 1 个名为 ClassificationFramework 的库中的函数。我将这个库作为头文件和 cpp 提供，所以基本上是源代码。在 Exe 解决方案中，我链接了我生成的库 + 一些其他库来运行它 + ClassificationFramework.dll。当我使用 Release 时一切正常，但是当我更改为 Debug 时(因为我想调试一些东西，我厌倦了在 Release模式下跳过调试器)我得到这个:

    2>Link:

当我在 Release 中构建时，我也收到了这些警告:

我发现调试器因为 pdb 文件路径错误而跳过。

当我转到 Debug->Windows->Modules 时，我看到他找不到那些 pdb 文件或其他东西。我怎么能说他这些文件在这里和这里？我试图以管理员身份运行 MSvisual，但这也无济于事。我使用 microsoft server 加载 pdb 文件，但也没有帮助。

Answer 1

在 VS2010 中迭代器调试级别在调试时默认为 2，在发布时被禁用。您使用的其中一个 dll 可能在调试中关闭了迭代器调试，因为它是在旧版本的 Visual Studio 中构建的，或者他们明确地将定义添加到项目中。

搜索 _ITERATOR_DEBUG_LEVEL 和 _SECURE_SCL 删除它们或在所有项目和源中适本地设置它们并重建所有内容。

_ITERATOR_DEBUG_LEVEL = 0 // disabled (for release builds)
_ITERATOR_DEBUG_LEVEL = 1 // enabled (if _SECURE_SCL is defined)
_ITERATOR_DEBUG_LEVEL = 2 // enabled (for debug builds)

简而言之，您可能正在混合发布和调试 dll。不要在调试中链接发布 dll，反之亦然!
