说明一下，在Ubuntu 16.04上安装SkyEye方法不是原创，是来自互联网，仅供学习参考。

一、检查支持软件包

gcc,
make,
vim(optional),
ssh,
subversion
binutils-dev (bfd)
atk-dev （libatk1.0-dev）
gtk+-2.0-dev （libgtk2.0-dev）
pkg-config
pango-dev （libpango1.0-dev）
freetype2-dev （libfreetype6-dev）
glib-dev （libglib2.0-dev）
x11-dev （libx11-dev）

建议您在终端里输入sudo apt-get install 软件包 来逐个检查，例如sudo apt-get install libx11-dev用来检x11-dev是否安装。我用Ubuntu16.04系统直接运行sudo apt-get install skyeye可以安装成功，安装的过程中如果系统提示缺少包，再按提示安装即可。

二、安装skyeye

1、建议在终端里输入sudo apt-get install skyeye来安装，这种方式安装默认安装的版本为1.2.5，。

2、也可以下载源码包进行编译安装，源码安装方法如下：

--------------------------------------------------------------------------------------------------------------------------

源码安装参考了：http://blog.csdn.net/xumin330774233/article/details/18703391

（1）、下载源码包skyeye-1.3.5_rc1.tar.bz2

（2）、解压源码包：

tar -jxvf skyeye-1.3.5_rc1.tar.bz2

（3）、安装一系列依赖库：

libgtk2.0-dev

pkg-config

libatk1.0-dev

libpango1.0-dev

libfreetype6-dev

libglib2.0-dev

libx11-dev

binutils-dev

libncurses5-dev

libxpm-dev

autoconf

automake

libtool

python-dev

根据不同的系统可能还需要其他一些依赖库，根据实际情况安装。

Ubuntu16.04默认安装了python2.7.11版本，所以我没有重新编译python源码和重新安装。

（4）、输入命令：

./configure --prefix=/opt/skyeye

make lib

make

make install_lib

make install

这几个步骤中可能会出现错误：

a、make lib的时候：libopcodes In function 'SUBWORDSISF': third-party/opcodes/cgen-ops.h:323: multiple definition

这个解决方法参考了：http://blog.csdn.net/u012140133/article/details/51943605

问题在于重复定义。具体而言，extern 变量或函数被包含时，可能被多个文件包含。因为 gcc 是对每个文件单独编译然后在对所有文件一起链接的，所以，在不声明全局变量的前提下，编译时不会报告错误而链接时会发生重复定义。

解决方法有两个：
1. 对于单个文件多次包含，可在被包含文件首末加上 #ifndef **  #define **  #endif
2. 对于多个文件多次包含，只能将被包含内容声明为 static

我们按提示找到 third-party/opcodes/cgen-ops.h 第 323 行，发现是一个 SEMOPS_INLINE 类型的宏函数，就是它被重复定义了。所以现在将其声明为 static 。其他类似的函数也要这么声明。

    ---28: #define SEMOPS_INLINE extern inline  +++28: #define SEMOPS_INLINE static inline  ---299: QI SUBWORDSIQI (SI, int);  ---300: HI SUBWORDSIHI (SI, int);  ---301: SI SUBWORDSFSI (SF);  ---302: SF SUBWORDSISF (SI);  ---303: DI SUBWORDDFDI (DF);  ---304: DF SUBWORDDIDF (DI);  ---305: QI SUBWORDDIQI (DI, int);  ---306: HI SUBWORDDIHI (DI, int);  ---307: SI SUBWORDDISI (DI, int);  ---308: SI SUBWORDDFSI (DF, int);  ---309: SI SUBWORDXFSI (XF, int);  ---310: SI SUBWORDTFSI (TF, int);  +++299: SEMOPS_INLINE QI SUBWORDSIQI (SI, int);  +++300: SEMOPS_INLINE HI SUBWORDSIHI (SI, int);  +++301: SEMOPS_INLINE SI SUBWORDSFSI (SF);  +++302: SEMOPS_INLINE SF SUBWORDSISF (SI);  +++303: SEMOPS_INLINE DI SUBWORDDFDI (DF);  +++304: SEMOPS_INLINE DF SUBWORDDIDF (DI);  +++305: SEMOPS_INLINE QI SUBWORDDIQI (DI, int);  +++306: SEMOPS_INLINE HI SUBWORDDIHI (DI, int);  +++307: SEMOPS_INLINE SI SUBWORDDISI (DI, int);  +++308: SEMOPS_INLINE SI SUBWORDDFSI (DF, int);  +++309: SEMOPS_INLINE SI SUBWORDXFSI (XF, int);  +++310: SEMOPS_INLINE SI SUBWORDTFSI (TF, int);  ---312: UQI SUBWORDSIUQI (SI, int);  ---313: UQI SUBWORDDIUQI (DI, int);  +++312: SEMOPS_INLINE UQI SUBWORDSIUQI (SI, int);  +++313: SEMOPS_INLINE UQI SUBWORDDIUQI (DI, int);  

b、make过程中可能出现的错误：

1、/usr/bin/ld: cannot find -lltdl，解决办法：可能是libtool未安装正确，重新输入命令sudo apt-get install libtool即可。

2、/usr/bin/ld: cannot find -liconv，解决办法：由于系统源中没有libiconv的库，所以要下载源码：ftp://gnu.mirror.iweb.com/libiconv/，下载源码后解压：

tar -zxvf libiconv-1.14.tar.gz

./configure --prefix=/usr/local
make
make install

make的时候出现：
./stdio.h:1010:1: error: ‘gets’ undeclared here (not in a function)
 _GL_WARN_ON_USE (gets, "gets is a security hole - use fgets instead");
修改libiconv-1.14/srclib/stdio.h文件，把上句中的gets改为fgets，重新make。

3、fatal error: gtk/gtk.h: No such file or directory  fatal error: glibconfig.h: No such file or directory等，解决办法：
首先查看系统中是否有该头文件存在，可以在/usr/include和/usr/lib下查找，查找命令为：find /usr/include | grep "gtk.h"，如果系统中不存在该头文件那么是相应的依赖库没有安装，先安装依赖库；如果系统中存在头文件那么是包含路径没有包含。如果因为包含路径没有包含，可以在Makefile文件中增加包含路径，例如在skyeye-1.3.5_rc1/device/touchscreen_s3c6410/touchscreen_s3c6410.c源文件中找不到头文件，可以在skyeye-1.3.5_rc1/device路径下的Makefile中增加头文件包含路径：

am__append_25 = -I/usr/include/gtk-2.0/ \
        　　　　　　  -I/usr/include/pango-1.0/ \
        　　　　          -I/usr/include/glib-2.0/ \
                                -I/usr/lib/i386-linux-gnu/glib-2.0/include/ \
                                -I/usr/lib/i386-linux-gnu/gtk-2.0/include/ \
                                -I/usr/include/cairo/        \
                                -I/usr/include/gdk-pixbuf-2.0/    \
                                -I/usr/include/atk-1.0/

以上步骤完成后可以进入到/opt/skyeye/bin目录下，输入命令./skyeye查看软件版本信息，这个时候可能会出现以下错误：

ImportError: /usr/lib/python2.7/lib-dynload/_ctypes.i386-linux-gnu.so: undefined symbol: PyFloat_Type

首先查看一下_ctypes.i386-linux-gnu.so对python的依赖库：

ldd /usr/lib/python2.7/lib-dynload/_ctypes.i386-linux-gnu.so

　linux-gate.so.1 =>  (0xb77a9000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xb774b000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xb7595000)
    libffi.so.6 => /usr/lib/i386-linux-gnu/libffi.so.6 (0xb758b000)
    /lib/ld-linux.so.2 (0x800a2000)
发现_ctypes.i386-linux-gnu.so并没有依赖python库，在/usr/lib/i386-linux-gnu/libpython2.7.so.1.0库中通过命令查看是否有PyFloat_Type的定义：

readelf -a /usr/lib/i386-linux-gnu/libpython2.7.so.1.0 | grep PyFloat_Type
00328c44  00016406 R_386_GLOB_DAT    00361ce0   PyFloat_Type
356: 00361ce0   196 OBJECT  GLOBAL DEFAULT   24 PyFloat_Type
可以看到libpython2.7.so.1.0中定义了PyFloat_Type，但是没找到解决方法 。偶然看到一个帖子上说可以通过加"-n"参数尝试不使用命令行启动，python主要是负责命令行的解析和显示的。

这样测试/opt/skyeye/testsuite/arm_hello程序就通过了，输入以下命令可以看到窗口一直打印helloworld：

/opt/skyeye/bin/skyeye -n -e arm_hello

出现上述问题时还有一种方法就是重新编译安装python2.7：

下载python2.7源码：https://www.python.org/downloads/release/python-2712/

加压源码：tar -zxvf Python-2.7.12.tgz

进入源码根目录并配置：./configure --enable-shared --enable-unicode=ucs4

sudo make

sudo make install

安装完毕后再次运行skyeye已经不会出现上述问题。

--------------------------------------------------------------------------------------------------------------------------------------------------------

三、检查skyeye安装是否正确

在终端中输入skyeye并回车，如果出现下面信息，说明安装正确。

**************************** WARNING **********************************

your elf-format image filename. Or you only want to run binary image,
you need to set the filename of the image and its entry in nf.

如果没有出现上面信息，而是出现：

skyeye: error while loading shared libraries: libbfd-2.19.90.20090909.so: cannot open shared object file: No such file or directory

解决方法：在Ubuntu 16.04中libbfd版本是libbfd-2.20.1-system.20100303.so，而需要的是libbfd- 2.19.90.20090909.so，手动创建符号链接即可，在终端中输入如下命令：sudo ln -s /usr/lib/libbfd-2.20.1-system.20100303.so /usr/lib/libbfd-2.19.90.20090909.so并回车，OK!在在终端中执行skyeye命令，会打印出正确信息。

4.测试

下载skyeye-testsuite-1.2.5，用tar jxvf解压，在终端中进入skyeye-testsuite-1.2.5/uClinux/at91/uclinux_cs8900a，执行以下命 令：sudo skyeye -e linux，会打印出如下信息：
