Android ndk 使用cmake构建工具链以交叉编译android
你好, 我的主机是Fedora19，我想创建一个工具链，用于编译在android上运行的程序，稍后我想将其扩展到iOS 我得到以下错误：Android ndk 使用cmake构建工具链以交叉编译android,android-ndk,cmake,cross-compiling,toolchain,Android Ndk,Cmake,Cross Compiling,Toolchain,你好, 我的主机是Fedora19，我想创建一个工具链，用于编译在android上运行的程序，稍后我想将其扩展到iOS 我得到以下错误： gcc (GCC) 4.8.1 android-ndk-r9 我不知道为什么会出现这个错误，因为所有的东西都已经安装好了。我还安装了binutils arm linux gnu。然而，这是我第一次做这种事情，所以我有很多东西混淆了 我正在尝试使用cmake创建一个工具链文件，以便在android设备上运行库 我已将android-ndk-r9安装在以下位

非常感谢，为什么不试试这个呢。我仍然使用这个脚本，它工作得相当好。如果这种方法不适合你的需要，你可以用它作为灵感：-） 我首先访问了这个网站，解决了这个问题： 有一个使用NDK附带的独立工具链的示例
