scue@Link:/media/scue/Source/JellyBean$ 

解决：自从gcc编译器更新至4.6之后出现的；
      把haware_samsung代码切换至jellybean-stable分支；
      或者手动修改hardware/samsung/exynos4/hal/libgralloc_ump/framebuffer_device.cpp此文件；

错误2：

解决：不知道哪个版本开始，不再使用surfaceflinger/ISurfaceComposer.h，而使用gui/ISurfaceComposer.h; 
      找到hardware/samsung/exynos4/hal/libhdmi/libhdmiservice/SecHdmiClient.h，把surfaceflinger修改为gui；


错误3：
=====================================================================================================
提示"DEV_NAME"第一次使用(error: 'DEV_NAME' undeclared)。

解决：多是DDC(直接数据控制)没有设置好导致的；
      在device/lenovo/sttutgart/BoardConfig.mk中，添加：
      BOARD_HDMI_DDC_CH := DDC_CH_I2C_7

测试机型：联想K860
