QT Necessitas - 链接gnu-libstdc ++时出现神秘的ctype_base.h错误

时间：2012-07-12 04:09:28

标签： android linux qt stl android-ndk

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，我已将其添加到项目中。当然，有很多未定义的引用错误（由于Qt Necessitas的性质，默认情况下没有在OS的include / lib路径中查找），所以我做了一些谷歌搜索并找到了解决方法。

现在，在看起来工作之后，我似乎得到了一些奇怪的错误，这些错误与GNU的Android / ARM stlport有关。

也为此搜索，发现this。如果您阅读了上一篇文章，那么OP最后会很难过，并且很难找出问题所在。我的错误似乎有点不同，但仍然与他/她相同的盟友。

基本上，我真的可以使用一些指导来解决这个问题。如果有人有任何想法或遇到同样的问题，我真的很感激你的建议！

底部是cbin_base.h的pastebin。

谢谢！

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

因为Qt的Necessitas NDK似乎落后了几个版本，所以我决定只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），所以我不能指望太多，但是在Eclipse中有一些非常不必要的错误经验后，我真的很想不得不回到那里再次。不要误会我的意思，如果你正在进行Java开发，那肯定是要走的路。只是...不适用于C ++;）

以下是我的.pro文件：

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

答案 0 :(得分：1)

我遇到了同样的问题。在我看来，问题似乎是由环境变量引起的，即“CPLUS_INCLUDE_PATH”和“C_INCLUDE_PATH”。这些变量包含了我的系统C ++的路径，我想这些路径干扰了armabi平台包含的内容。

解决方案：我只是取消了这两个环境。变量
