Have you rｕｎ it correctly?

[adzienis]

You need to add that library to be linked. There's a section in the Makefile ($LIBRARIES), so add opencv_imgcodecs to it, assuming opencv is installed correctly.

@panlanlan imgcodecs是opencv3/opencv4里拆出来的模块，opencv2里没有。你得在makefile里加一下。P.S 我新增了cmake支持，也可以试一下，应该更容易一些。
