当我尝试使用 gli/gli.hpp 进行编译时，出现以下错误。我以前从未接触过这些文件。所以我不知道如何解决这个问题。

我认为问题在于您没有告诉编译器您需要使用 C++11 标准进行编译。

如果您使用的是 gcc，那么您必须通过

-std=c++11

在你的命令行上（或者 -std=c++0x 如果你使用的是旧版本的 gcc）

简短的回答似乎是您的 C++ 编译器比用于开发 gli 的编译器更严格。-fpermissive通过错误，第一个可以通过在您的g++线路上添加来静音（不一定正确修复） 。这个错误看起来像是来自使用错误的返回类型gli::storage::format()

以下错误似乎是包含错误头文件的情况。特别是，load_dds.hpp包括另一个头文件 ( storage.hpp)，其中包括<cstring>，而不是<string>，这是 C++ 声明std::string的 . 快速修复是添加<string>到storage.hpp您下载的副本中，并提交错误。

In file included from /usr/include/gli/gli.hpp:51:0,
             from window.cpp:4:
/usr/include/gli/./core/load_dds.hpp:37:3: error: ‘string’ is not a member of ‘std’

对于这个，我认为问题在于 in被定义为一个函数load_dds.hpp，gli::loadStorageDDS但没有标记为 being inline，这就是 in 正在发生的事情load_dds.inl。该.inl机制似乎是微软的混合物，因此您可能需要修改.hpp以包含.inl实现以保持一致。（这是一个猜测，顺便说一句）。
