  ------进行尝试，为了安装OpenMAX。
  make报错，‘/usr/bin/ld: cannot find -lopenmaxil’
  ??!!!
  openmaxil无法直接install，’ sudo apt-cache search openmaxil '无结果
  'sudo apt-cache search openmax’下有结果，装了所有并更新，并未有什么影响

  ------OpenMAX IL Bellagio安装make报错

  ------检查vc 是否在机器上装好了 Video Core。
  应该已经安装，
  '/opt/vc/'下已经有相关文件，相关命令有回应
  安装过程参考教程raspberryPiClub内搜索内容
  (不知为何raspberryPiClub网站打不开了！！？)

安装OpenMAX（说要装openmaxil）

sudo apt-get install libjpeg9-dev libpng-dev

git clone https://github.com/HaarigerHarald/omxiv

cd omxiv
make ilclient
make

据说这步之后openmax将被安装，但是make报错error
[Error----]

OpenMAX IL Bellagio安装（）

（没openmaxil？）
按照包内install的步骤`bash ./configure; make; make instal
case value ‘2130706435’ not in enumerated type ‘OMX_INDEXTYPE’ [-Werror=switch]
好像是编译错误？
