hi你好，我在执行 ./capture-image-from-camera-using-opencv.sh这个脚本的时候报错：
Compiling /home/pi/workspace/camera/raspberry-pi/webcam/image-capture/opencv/webcam.c ...

请问这个是什么问题呢
我的树莓派版本是B+，sudo apt-get install libopencv-dev python-opencv使用这种方式安装的opencv

Could you please tell me how to correct such problems，thanks.

When Mongoose web server embedded in the timer-sense-light started in a thread, it crashed immediately.
It seems that it's because of specifying the web-root for mongoose web server caused the problem, but don't konw why.

GDB debug guide

• turn on the core dump for Arch Linux ARM

  ulimit -c unlimited
  sysctl -w kernel.core_pattern=core

• modify Makefile to include debugging info in the binary executable program

  DEBUG = YES

• compile & run the program

  make && make install
  cd deploy/bin && ./run-timer-sense-light.sh

You'll find that a core.xxx(e.g. core.4929) file generated under the same dir as the timer-sense-light executable program.

• run GDB

  gdb timer_sense_light core.xxx
  set args /root/raspberry-pi/gpio/timer-sense-light/deploy/conf/main.conf /root/raspberry-pi/gpio/timer-sense-light/deploy/conf/time-range.txt

It seems that it's because of glog conflicts with the latest Mongoose.

你好，我在学习timer sense light项目，在接线图里面 input 与output 里面关于接地的黑线都接在树莓派的同一个位置，请问这块怎么处理呢
