树莓派启动Python脚本也是件让人头疼的事情，不符合Linux常理，简直了。
根据以往的做法，把需要执行的程序放入/etc/rc.local文件里。使用任何需要加的程序脚本都可以，唯独Python不行，气人。
通过解析报错原因，提示无法打开Python，猜测跟权限有关，各种尝试，都无效。
通过网上资料，说明可以通过desktop来启动程序，这话我信了，没有不信的理由了。尝试在./config目录下创建 autostart 文件夹，并在里面创建了第一个启动配置文件mystart.desktop。别说还真好使，但请注意权限问题。

根据电脑操作系统位数选在不同的安装包，点击下载。
根据提示选择安装目录，根据实际情况选择，建议默认。
根据以上猛如虎的操作，cygwin算是安装完成，但是make等一些操作还是无法完成。
安装wget并添加了环境变量后，cygwin需要重新打开才能找到wget
上面wget和apt-cyg 弄好后 ， cygwin64 应用终端输入命令 make 发现make 命令 找不到，用apt-cyg安装 相关包
apt-cyg install gcc
apt-cyg install glibc-dev
apt-cyg install automake
apt-cyg install make
安装完后，make 能用了

./configure --enable-iconv=no --with-libiconv=gnu
回到源码根目录继续编译吧
1.whereis 文件名
特点:快速,但是是模糊查找
例如：
whereis php #会把php,php.ini,php.*所在的目录都找出来.
2.find / -name 文件名
特点:准确,但速度慢,消耗资源大
例如：
如果想找到php.ini的准确位置,需要用
#find / -name php.ini
3.locate 文件名
最快,最好的方法.
注意:第一次使用该命令,可能需要更新数据库,按照提示的命令执行一下就好了.

因为新版的perl不在支持左大括号的使用，
进入这个文件删掉大括号，问题解决。
