【问题描述】:
是否可以在托管 C++ DLL 中使用 stlport?
在我的项目中,我从 stlport 内容的链接器中收到了几个“未解析的令牌”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!?有什么想法吗?
【问题讨论】:
-
如果错误消息不完整且未提供代码,则会阻碍帮助。
-
我更新了来自链接器的错误消息。我希望这会有所帮助!
-
你在用VC++吗?如果是这样,您是否尝试过内置的 STL?另外,您是否也在混入 Qt(我猜是“moc_”的东西)?在.Net之上堆放Qt和第三方STL似乎有点过分……
-
你是对的。我正在使用 Qt。而且我已经成功地使用 Stlport 构建了 Qt,没有任何问题,因为它只是非托管代码。我只在 .NET 模块中遇到问题,它试图使用一些非托管 DLL。内置的 STL 不是一个选项,因为在调试版本中性能很差,我们需要一些选项来减少 STL 的调试开销。这就是我们选择 stlport 的原因。
