是否可以在托管 C++ DLL 中使用 stlport？

在我的项目中，我从 stlport 东西的链接器中收到了几个“未解决的令牌”错误。例如：

我检查了这些函数是否包含在 stlport 库/DLL 中，并且这些函数存在一个稍微不同的未修饰名称。所以我想调用约定有问题！？有任何想法吗？

我解决了这个问题。问题是 stlport 编译时将 wchar_t 视为内置类型，而 .NET 部分是在没有此选项的情况下编译的。

因此 wchar_t 在 .NET 中被视为 unsigned short 并导致无法解析的外部符号。

C++ 编译器使用名称修饰，例如。使用 MSVC++ 6/7 编译时，"void h(int)" 变为 "?h@@YAXH@Z"

然而，编译器之间的名称转换不同，甚至编译器版本之间也不同。您的 DLL 可能是使用不同的编译器或使用不同名称的旧版本的编译器编译的。尝试使用您正在使用的编译器重新编译库。
