QT Necessitas - 鏈接gnu-libstdC++時的神祕ctype_base.h錯誤

Question

我在Necessitas版本的Qt Creator中開始了一個Qt移動應用程序項目，專門針對API 15。從那裏，我有一些我在Eclipse中編寫的C++源代碼，我添加到了該項目中。當然，還有很多未定義的引用錯誤（由於Qt Necessitas默認情況下沒有在操作系統的include/lib路徑中查找），所以我做了一些Google搜索並找到了一個解決方案。

現在，之後似乎工作，我似乎得到一些奇怪的錯誤，處理與Android/ARM的GNU的stlport。

谷歌搜索，以及發現this。如果你閱讀最後一篇文章，OP最終很難被發現，並且很難找出問題所在。我的錯誤似乎有點不同，但仍然和他/她的相同。

基本上，我可以真正使用一些指導如何解決這個問題。如果有人有任何想法或已經遇到同樣的問題，我真的很感激建議！

底部是ctype_base.h的pastebin。

謝謝！

在該問題

所以，因爲我連接的GNU的libstdC++（在.so版本，據我所知），我在ctype_base.h收到以下錯誤：

由於Qt的Necessitas NDK似乎有兩個版本，我決定用我收到的最新版本進行推出。當然，Necessitas還不完全穩定（仍然在Alpha 3，IIRC中），所以我不能期望太多，但是在Eclipse中有一些非常不必要的錯誤診斷體驗之後，我真的很討厭必須回到那裏再次。不要誤會我的意思，如果你在做Java開發，那絕對是一條可行的路。只是......不是C++;）

這是我的.pro文件以及：

而且，這裏的ctype_base.h

Answer 1

的pastebin我經歷了同樣的問題。在我看來，問題似乎是由環境變量引起的，即「CPLUS_INCLUDE_PATH」和「C_INCLUDE_PATH」。這些變量包含我的系統的路徑C++包括哪些，我猜是干擾了armabi平臺包括。

解決方案：我只是取消設置這兩個env。變量。
