【问题标题】：Compiling in Debug configuration works fine, but Release gives link errors在 Debug 配置中编译工作正常，但 Release 给出链接错误
【发布时间】：2018-08-13 12:13:02
【问题描述】：

我在 Visual Studio 2017 中使用 GLFW（glfw3.lib，而不是 glfw3dll.lib）和 GLAD（glad.c）。在调试配置中编译工作正常，而发布版本会抛出奇怪的链接器错误。这些是“未解析的外部符号”：

运行时库选项是“多线程 DLL”（“多线程调试 DLL”用于调试）。我正在使用预编译的 Windows GLFW 二进制文件。 Windows SDK 是 Windows 10 SDK。

感谢任何帮助。

我检查了包含目录的发布，结果发现它是错误的架构（32 位而不是 64 位）。但是现在它给出了另一个未解决的外部列表：

请注意，32 位 Release 可以正常工作，但 64 位 Release 版本会出现这些奇怪的链接器错误。

【问题讨论】：

您是否真的将 .libs 添加到发布模式的配置中？您可以为每个配置设置选项，所以我怀疑您这样做是为了调试，而不是为了发布。
@Zinki Additional Include Directories 是正确的，我检查了两次。要包含的实际库在包含在所有配置中的标头 (#pragma comment(lib, "glfw3.lib")) 中指定。
@HansPassant 我编辑了问题，提供了更多细节
看起来像是链接到发布应用程序的 glfw3.lib bing 的调试版本
@AlanBirtles 所以我应该在发布配置中从源代码重建 GLFW，然后将其链接到我的应用程序？

标签： c++ visual-c++ glfw

【解决方案1】：

由于某种原因，64 位 GLFW 预构建的 Windows 二进制文件为 Debug，因此无法链接，因为我的应用位于 Release 中，未提供必要的调试定义。解决方案是在发布配置中自己从源代码编译 GLFW，或者根本不使用 64 位 GLFW（奇怪的是 32 位二进制文件是 Release，因为我能够在 x86/Release 中构建我的应用程序） .但是，我无法实际证明这一点，因为我不再使用 GLFW，因为它不能完全满足我的需求。
