cmake失敗與Android ndk

Question

我想建立一些使用Android NdK獨立工具鏈。但是，我遇到了這些錯誤。

 CMake Warning at cmake/android.toolchain.cmake:387 (message):

有兩組錯誤。我不知道從第一組開始。 android.toolchain.cmake文件默認查看sysroot，但沒有安裝android，Google也沒有要求我在那裏安裝它。

關於CMAKE變量，我發現大多數解決方案都涉及安裝開發人員工具，我已經有了。我嘗試手動設置CXX和CC變量，但沒有幫助。

任何想法從哪裏開始？

謝謝。

好的，我會在這裏做一些猜測，但我認爲你使用的是http://code.google.com/p/android-cmake/，並且在ANDROID_STANDALONE_TOOLCHAIN中爲它提供了NDK的路徑。如果我是對的，那就是問題所在。

您應該使用ANDROID_NDK調用它併爲您的NDK提供路徑。 android-cmake文檔表明這是要走的路。

或

跟上ANDROID_STANDALONE_TOOLCHAIN調用它，但它提供的路徑安裝的toochain（與make-standalone-toolchain.sh創建的東西）

如果你想要走這條路，您可以在安裝的NDK的docs/STANDALONE-TOOLCHAIN.html中找到有關創建獨立工具鏈的信息。
