“undefined reference to `TIFFReadRGBAStrip@LIBTIFF_4.0'” 问题解决方法

在安装Caffe 的过程中可能会遇到如下问题：

make[1]: *** [examples/CMakeFiles/classification.dir/all] Error 2

这是由于 openCV 库有多个产生的问题，这里我预先安装了 anaconda ，由于默认把 anaconda 的路径已经加到了环境变量中，这里我们还是用系统自带的 python 2 里面的 opencv 比较不容易产生问题，我的解决方法就是：

sudo gedit  ~/.bashrc

然后把 最后 Anaconda 的路径前面加 # 给注释掉：

# export PATH=/path/to/anaconda/bin:$PATH

然后：

source ~/.bashrc

为了保险起见，source 完以后可以再 注销账户 重新登录以下。
尝试 make clean 然后重新编译。
