今天编译caffe ,本来编译过无数次caffe了，基本坑都能解决的。但这次惹恼我了。一直搞不定。
错误信息是这样的：

感觉是一个包没有：
网上说装这个包：
sudo apt-get install libtiff4-dev
装好了也没有用。
折腾了半天，索性卸载，然后把 anaconda2下面的 libtiff.so移走。
2064 sudo apt-get remove libtiff4-dev
2065 locate libtiff.so
2066 mv /home/zenggq/anaconda2/lib/libtiff.so* ~/zenggq/bak/
再次编译，他成功了，并且在anaconda2下面自动又创建了libtiff.so。
/home/zenggq/anaconda2/lib/libtiff.so
/usr/lib/x86_64-linux-gnu/libtiff.so
/usr/lib/x86_64-linux-gnu/libtiff.so.5
/usr/lib/x86_64-linux-gnu/libtiff.so.5.2.0
估计是冲突了。什么鬼问题都有。既然我填坑了就把它分享给大家。
