解决步骤：

（1）查看opencv类型：

pkg-config opencv --modversion

2.4.9.1

或者：

![20190521195306879.png][]

因此，不能通过放开makefile.config中的opencv\_version:=3的方式

（2）修改makefile.config和makefile

makefile文件：

LIBRARIES += opencv\_core opencv\_highgui opencv\_imgproc 后加上：opencv\_imagecodecs

makefile.config文件添加：

LINKFLAGS := -Wl,-rpath,/home/xuqiong/anaconda2/lib

（3）重新编译成功

sudo make clean

sudo make all -j8
