android - 使用 Android NDK 编译命令行 C 应用程序

Question

我正在尝试编译Frotz在终端模拟器中运行，以便它将在我的 Android Ice Cream Sandwich 智能手机上执行。 Frotz 是一个开源的 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。我已完成以下操作:

• 下载 Android NDK (android-ndk-r8d) 并将其解压到我的 Windows 7 笔记本电脑上。 (提取到c:\android\android-ndk-r8d)
• 下载并安装了 Cygwin，包括所有开发包。 (所以 make 已安装)
• 使用 Cygwin，导航到包含提取的 Frotz makefile 和源文件夹的文件夹，然后尝试执行 make。

当我尝试运行 make 时，遇到与找不到 curses.h 相关的问题(但这个问题不是这个问题的重点；也许是一个要点后续问题)。当我执行 make Dumb (编译 Frotz 的简化版本)时，编译成功，并且我能够在 Cygwin 中运行它。但是，如果我将编译的命令行应用程序复制到手机并尝试执行它，则会收到以下错误:

not executable: magic 4D5A

我怀疑这里的问题是现在没有为 Arm 架构编译可执行文件。 make 文件中有以下行:

CC = gcc

我尝试更改为:

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

但是现在当我执行make时，我收到以下错误消息:

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

我对 C 开发(和 Android)非常陌生，正在努力弄清楚如何更改 makefile，以便它能够为 Android 正确编译。我将在下面包含完整的 makefile，并感谢任何人可以提供的任何帮助，以使其正确编译为 Android。

完整的Frotz makefile:

# Define your C compiler.  I recommend gcc if you have it.
# MacOS users should use "cc" even though it's really "gcc".
#
CC = gcc
#CC = cc

# Define your optimization flags.  Most compilers understand -O and -O2,
# Standard (note: Solaris on UltraSparc using gcc 2.8.x might not like this.)
#
OPTS = -O2

# Pentium with gcc 2.7.0 or better
#OPTS = -O2 -fomit-frame-pointer -malign-functions=2 -malign-loops=2 \
#-malign-jumps=2

# Define where you want Frotz installed.  Usually this is /usr/local
PREFIX = /usr/local

MAN_PREFIX = $(PREFIX)
#MAN_PREFIX = /usr/local/share

CONFIG_DIR = $(PREFIX)/etc
#CONFIG_DIR = /etc

# Define where you want Frotz to look for frotz.conf.
#
CONFIG_DIR = /usr/local/etc
#CONFIG_DIR = /etc
#CONFIG_DIR = /usr/pkg/etc
#CONFIG_DIR =

# Uncomment this if you want color support.  Most, but not all curses
# libraries that work with Frotz will support color.
#
COLOR_DEFS = -DCOLOR_SUPPORT

# Uncomment this if you have an OSS soundcard driver and want classical
# Infocom sound support.
#
#SOUND_DEFS = -DOSS_SOUND

# Uncomment this too if you're running BSD of some sort and are using
# the OSS sound driver.
#
#SOUND_LIB = -lossaudio

# Define your sound device
# This should probably be a command-line/config-file option.
#
#SOUND_DEV = /dev/dsp
#SOUND_DEV = /dev/sound
#SOUND_DEV = /dev/audio

# If your vendor-supplied curses library won't work, uncomment the
# location where ncurses.h is.
#
#INCL = -I/usr/local/include
#INCL = -I/usr/pkg/include
#INCL = -I/usr/freeware/include
#INCL = -I/5usr/include
#INCL = -I/path/to/ncurses.h

# If your vendor-supplied curses library won't work, uncomment the
# location where the ncurses library is.
#
#LIB = -L/usr/local/lib
#LIB = -L/usr/pkg/lib
#LIB = -L/usr/freeware/lib
#LIB = -L/5usr/lib
#LIB = -L/path/to/libncurses.so

# One of these must always be uncommented.  If your vendor-supplied
# curses library won't work, comment out the first option and uncomment
# the second.
#
CURSES = -lcurses
#CURSES = -lncurses

# Uncomment this if your need to use ncurses instead of the
# vendor-supplied curses library.  This just tells the compile process
# which header to include, so don't worry if ncurses is all you have
# (like on Linux).  You'll be fine.
#
#CURSES_DEF = -DUSE_NCURSES_H

# Uncomment this if you're compiling Unix Frotz on a machine that lacks
# the memmove(3) system call.  If you don't know what this means, leave it
# alone.
#
#MEMMOVE_DEF = -DNO_MEMMOVE

# Uncomment this if for some wacky reason you want to compile Unix Frotz
# under Cygwin under Windoze.  This sort of thing is not reccomended.
#
#EXTENSION = .exe

使用 android-ndk-r8d，您不需要 cygwin:make 可以在 c:\android\android-ndk-r8d\prebuilt\windows32\bin 中找到。

无论如何，要使用 makefile，您应该按照 c:\android\android-ndk-r8d\STANDALONE-TOOLCHAIN.html 中的说明进行操作
