說明一下，在Ubuntu 16.04上安裝SkyEye方法不是原創，是來自互聯網，僅供學習參考。
一、檢查支持軟件包
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）
建議您在終端里輸入sudo apt-get install 軟件包 來逐個檢查，例如sudo apt-get install libx11-dev用來檢x11-dev是否安裝。我用Ubuntu16.04系統直接運行sudo apt-get install skyeye可以安裝成功，安裝的過程中如果系統提示缺少包，再按提示安裝即可。
二、安裝skyeye
1、建議在終端里輸入sudo apt-get install skyeye來安裝，這種方式安裝默認安裝的版本為1.2.5，。
2、也可以下載源碼包進行編譯安裝，源碼安裝方法如下：
--------------------------------------------------------------------------------------------------------------------------
源碼安裝參考了：http://blog.csdn.net/xumin330774233/article/details/18703391
（1）、下載源碼包skyeye-1.3.5_rc1.tar.bz2
（2）、解壓源碼包：
tar -jxvf skyeye-1.3.5_rc1.tar.bz2
（3）、安裝一系列依賴庫：
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
根據不同的系統可能還需要其他一些依賴庫，根據實際情況安裝。
Ubuntu16.04默認安裝了python2.7.11版本，所以我沒有重新編譯python源碼和重新安裝。
（4）、輸入命令：
./configure --prefix=/opt/skyeye
make lib
make
make install_lib
make install
這幾個步驟中可能會出現錯誤：
a、make lib的時候：libopcodes In function 'SUBWORDSISF': third-party/opcodes/cgen-ops.h:323: multiple definition
這個解決方法參考了：http://blog.csdn.net/u012140133/article/details/51943605
問題在於重復定義。具體而言，extern 變量或函數被包含時，可能被多個文件包含。因為 gcc 是對每個文件單獨編譯然后在對所有文件一起鏈接的，所以，在不聲明全局變量的前提下，編譯時不會報告錯誤而鏈接時會發生重復定義。
解決方法有兩個：
1. 對於單個文件多次包含，可在被包含文件首末加上 #ifndef ** #define ** #endif
2. 對於多個文件多次包含，只能將被包含內容聲明為 static
我們按提示找到 third-party/opcodes/cgen-ops.h 第 323 行，發現是一個 SEMOPS_INLINE 類型的宏函數，就是它被重復定義了。所以現在將其聲明為 static 。其他類似的函數也要這么聲明。
---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過程中可能出現的錯誤：
1、/usr/bin/ld: cannot find -lltdl，解決辦法：可能是libtool未安裝正確，重新輸入命令sudo apt-get install libtool即可。
2、/usr/bin/ld: cannot find -liconv，解決辦法：由於系統源中沒有libiconv的庫，所以要下載源碼：ftp://gnu.mirror.iweb.com/libiconv/，下載源碼后解壓：
tar -zxvf libiconv-1.14.tar.gz
./configure --prefix=/usr/local
make
make install
make的時候出現：
./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改為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，解決辦法：
首先查看系統中是否有該頭文件存在，可以在/usr/include和/usr/lib下查找，查找命令為：find /usr/include | grep "gtk.h"，如果系統中不存在該頭文件那么是相應的依賴庫沒有安裝，先安裝依賴庫；如果系統中存在頭文件那么是包含路徑沒有包含。如果因為包含路徑沒有包含，可以在Makefile文件中增加包含路徑，例如在skyeye-1.3.5_rc1/device/touchscreen_s3c6410/touchscreen_s3c6410.c源文件中找不到頭文件，可以在skyeye-1.3.5_rc1/device路徑下的Makefile中增加頭文件包含路徑：
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/
以上步驟完成后可以進入到/opt/skyeye/bin目錄下，輸入命令./skyeye查看軟件版本信息，這個時候可能會出現以下錯誤：
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對python的依賴庫：
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)
發現_ctypes.i386-linux-gnu.so並沒有依賴python庫，在/usr/lib/i386-linux-gnu/libpython2.7.so.1.0庫中通過命令查看是否有PyFloat_Type的定義：
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中定義了PyFloat_Type，但是沒找到解決方法 。偶然看到一個帖子上說可以通過加"-n"參數嘗試不使用命令行啟動，python主要是負責命令行的解析和顯示的。
這樣測試/opt/skyeye/testsuite/arm_hello程序就通過了，輸入以下命令可以看到窗口一直打印helloworld：
/opt/skyeye/bin/skyeye -n -e arm_hello
出現上述問題時還有一種方法就是重新編譯安裝python2.7：
下載python2.7源碼：https://www.python.org/downloads/release/python-2712/
加壓源碼：tar -zxvf Python-2.7.12.tgz
進入源碼根目錄並配置：./configure --enable-shared --enable-unicode=ucs4
sudo make
sudo make install
安裝完畢后再次運行skyeye已經不會出現上述問題。
--------------------------------------------------------------------------------------------------------------------------------------------------------
三、檢查skyeye安裝是否正確
在終端中輸入skyeye並回車，如果出現下面信息，說明安裝正確。
**************************** WARNING **********************************
If you want to run ELF image, you should use -e option to indicate
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.

如果沒有出現上面信息，而是出現：
skyeye: error while loading shared libraries: libbfd-2.19.90.20090909.so: cannot open shared object file: No such file or directory
解決方法：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，手動創建符號鏈接即可，在終端中輸入如下命令：sudo ln -s /usr/lib/libbfd-2.20.1-system.20100303.so /usr/lib/libbfd-2.19.90.20090909.so並回車，OK!在在終端中執行skyeye命令，會打印出正確信息。
4.測試
下載skyeye-testsuite-1.2.5，用tar jxvf解壓，在終端中進入skyeye-testsuite-1.2.5/uClinux/at91/uclinux_cs8900a，執行以下命 令：sudo skyeye -e linux，會打印出如下信息：
