使用Android NDK编译命令行C应用程序

Question

我正在编译Frotz以在terminal emulator中运行，因此它会在我的Android冰淇淋三明治智能手机上执行。 Frotz是一款开放源代码的Z-Machine解释器，用于播放交互式小说，基本上只是一个命令行应用程序。我已经完成了以下操作：

• 下载Android NDK（android-ndk-r8d）并将其解压缩到我的Windows 7笔记本电脑上。 （提取到c:\android\android-ndk-r8d）
• 下载并安装了Cygwin，包括所有的开发包。 （所以make安装）
• 使用Cygwin，导航到包含所提取了frotz生成文件和源文件夹的文件夹，并尝试执行make。

当我尝试运行make，我遇到不被发现与curses.h问题（但这个问题是不是这个问题的重点，也许对后续问题的一个点）。当我做make dumb（编译一个简化版本的Frotz）时，编译成功，我可以在Cygwin内运行它。但是，如果我的编译命令行应用程序复制到手机，并尝试执行它，我收到以下错误：

not executable: magic 4D5A

我怀疑这里的问题是，可执行文件现在还没编译为ARM架构。 make文件中有如下一行：

CC = gcc 

，我试图改变到：

CC = /cygdrive/c/android/android-ndk-r8d/toolchains/arm-linux-androideabi-4.7/prebuilt/windows/bin/arm-linux-androideabi-gcc.exe 

但现在当我执行make，我收到以下错误信息：

fatal error: signal.h: No such file or directory 

我对C开发（和Android）非常陌生，并且很难弄清楚如何更改makefile以便它能够正确编译Android。我将在下面包含完整的makefile，并会很感激任何人可以提供的帮助正确编译Android的帮助。

有Android NDK-R 8d中，你不需要Cygwin的：使可以在C发现：\机器人\ Android的NDK-R 8d中\预建\ WINDOWS32 \完事。

不管怎么说，使用一个makefile，你应该按照说明在C：\机器人\ Android的NDK-R 8d中\ STANDALONE-TOOLCHAIN.html
