Getting error: ‘IplImage’ does not name a type when building with latest opencv

[nyierr]

I am getting this error when building darknet with opencv enabled:

./src/image_opencv.cpp:12:1: error: ‘IplImage’ does not name a type
 IplImage *image_to_ipl(image im)
 ^~~~~~~~
compilation terminated due to -Wfatal-errors.
Makefile:86: recipe for target 'obj/image_opencv.o' failed
make: *** [obj/image_opencv.o] Error 1

Any idea how to fix it?

A change by tiagoshibata resolved this problem and I have built darknet successfully.

However, when ran the following to confirm all is good, I got an error:

$ ./darknet imtest data/eagle.jpg
./darknet: error while loading shared libraries: libopencv_highgui.so.4.3: cannot open shared object file: No such file or directory

This was resolved by running:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib

I have the same problem, why you guys do not correct the project once for all?
