Can't compile. about ros_openpose HOT 6 CLOSED

Hi @Gryogor

I quickly looked at the error and found the following-

error: no match for ‘operator=’ (operand types are ‘op::Matrix’ and ‘const cv::Mat’)
datumPtr->cvInputData = colorImage;

I highly doubt that you are using a really old version of OpenPose. Can you please install OpenPose version 1.5.1? The latest version of OpenPose should also work fine.

Thank you for the answer. I will try it. But how does your wrapper checks, which openpose to choose? Because I have 2 versions installed in different folders.
UPD. One of the versions is the most recent. Installed it today.

It uses find_package as shown below:

I have 2 versions installed in different folders.

As I said earlier, find_package must be able to located the latest OpenPose. To do that you must copy the compiled files into the system directories. You need to go inside the build directory of OpenPose and then execute the following command-

cd build/
sudo make install

You can look at the detailed instructions here.

Tried the most recent commit and version 1.5.1. Still gives the same error.

Okey. I tried to install everything on completely clean ubuntu 16.04. This time everything worked without a problem. I am not sure what is the problem, but maybe older versions of installed openpose might be creating a problem.

I am glad that it worked.

Yes, you are right. You can't have two versions of the same software installed system directories (globally). The command sudo make install basically overwrites your exiting OpenPose. Furthermore, I don't see any benefit of having multiple versions of OpenPose in one computer.
