我在 Qt Creator 的 Necessitas 版本中启动了一个 Qt 移动应用程序项目，专门针对 API 15。从那里，我有一些我在 Eclipse 中编写的 C++ 源代码，我将它们添加到项目中。当然，有很多未定义的参考错误（由于 Qt Necessitas 的性质，默认情况下不查看操作系统的 include/lib 路径），所以我做了一些谷歌搜索并找到了修复。

现在，在这似乎工作之后，我似乎遇到了一些奇怪的错误，这些错误涉及 GNU 的 Android/ARM stlport。

谷歌搜索了一下，发现了这个。如果您阅读了最后一篇文章，那么 OP 最终会非常难过，并且很难找出问题所在。我的错误似乎有点不同，但仍然相对于他/她的同盟。

基本上，我真的可以使用一些指导来解决这个问题。如果有人对此有任何想法或遇到同样的问题，我将非常感谢您的建议！

底部是 ctype_base.h 的 pastebin。

谢谢！

解决问题

所以，因为我正在链接 gnu-libstdc++（.so版本，AFAIK），我收到了以下错误ctype_base.h：

因为 Qt 的 Necessitas NDK 似乎落后了几个版本，所以我决定使用我收到的最新版本。当然，Necessitas 还没有完全稳定（仍然在 Alpha 3，IIRC 中），所以我不能期待太多，但是在 Eclipse 中经历了一些非常不必要的错误之后，我真的不想回到那里再次。不要误会我的意思，如果你在做 Java 开发，那绝对是要走的路。只是...不适用于 C++ ;)

这也是我的.pro文件：

# and 0x2002CCCF value if protected UID is given to the application

我遇到了同样的问题。就我而言，问题似乎是由环境变量引起的，即“CPLUS_INCLUDE_PATH”和“C_INCLUDE_PATH”。这些变量包含指向我的系统 C++ 的路径，我猜这些路径会干扰 armabi 平台的包含。

解决方案：我只是取消设置这两个环境。变量。
