undefined reference to symbol ‘_ZN2cv6String10deallocateEv

使用qt编译Caffe时出现如下错误:
undefined reference to symbol ‘_ZN2cv6String10deallocateEv‘
error adding symbols: DSO missing from command line
 
原因是因为出现了opencv 高低版本的冲突,TX2 本身已经安装了opencv3.4,而安装caffe时又执行了:
apt-get install libopencv-dev
 
从而出现了opencv版本冲突问题,解决办法是执行:
sudo apt-get autoremove libopencv-dev
