【问题描述】：
与boost::serialization 链接时，我的项目“发布”版本出现问题。我的“调试”和“发布”版本之间唯一真正的区别是我在调试中定义了DEBUG 并使用-O0，我在发布中定义了NDEBUG 并使用-O3。
我可以在调试模式下完全编译、链接和运行。
但是，当我使用发布模式编译时，它会编译正常但在链接过程中失败并出现以下错误：

我不明白这一点，因为所讨论的方法已完全定义。我不会在这些类的代码中执行任何类型的#ifdef NDEBUG 等宏。
有人明白为什么会发生这种情况吗？
我的 Texture2D 课程：
Texture2D.hpp
Texture2D.cpp
我的 TextureManager 类：
TextureManager.hpp
TextureManager.cpp
如果有帮助，我很乐意提供更直接/本地化的代码 sn-ps。
更新：如果我将serialize 方法的定义移动到头文件中，它会突然链接！我想这与它们是模板方法有关，但我仍然不明白为什么我的“调试”构建工作但我的“发布”构建却没有......
