我有一个用 C++ 1996 编写的程序，我想将它编译为 C++ 17。添加 #include 时收到一条错误消息，我被称为 cstdint。这缺少以下声明：

如果我用 c++ 98 编译程序，我没有问题。

以前有没有人遇到过，或者您知道解决方案吗？

解决了我的程序，并很高兴分享它。经过大量搜索，我偶然发现了CSTDINT / STRING问题的原因。

在#INCLUDE STRING 中调用#INCLUDE CSTDINT 函数，在#INCLUDE CSTDINT 中调用#INCLUDE STDINT.H。现在我的程序中还有一个 stdint.h，编译器中也有一个，这就产生了问题。

如何解决。在程序中找到stdint.h文件，将其删除。这就是所有人
