Hello, I am using ROS for ROS point cloud visualizer with IWR6843ISK. I a using Oracle VB Ubuntu 18.04LTS.First time installation and building packages were successfully build. But I had to reset my VM . After that whenever I build the package error is showing. I have copied the error showed in terminal. Please help. I had gone through many Q and A. But I could't find nothing. I have reinstalled everything many times. Nothing went right. Thanks in advance. Thanks and regards, Aleena NA

Edit 3: it's more likely the following is the problem (from here):

POINT_CLOUD_REGISTER_POINT_STRUCT (MyPointType,
                                    (float, x, x)
                                    (float, y, y)
                                    (float, z, z)
                                    (float, intensity, intensity)
                                    (float, velocity, velocity))

It doesn't appear MyPointType is defined anywhere in that package, so the compiler is correct to complain about it.

This is a problem with the code provided by Texas Instruments.

I'd suggest to contact them and ask them for support.

Edit 2: ah, TI didn't use find_package(PCL ... EXACT), so CMake is happy with anything at least version 1.7.2, which 1.8.x of course is:

Found PCL: ... Required is at least version "1.7.2"

But again: it could be something else is the real cause, and the version difference is a red herring.

Edit: I just found what appears to be the official Git repository hosted by Texas Instruments themselves: git.ti.com/mmwave_radar/mmwave_ti_ros. The files there also seem to suggest PCL 1.7.2 is a requirement (from here):

find_package(PCL 1.7.2 REQUIRED)

I'm not really sure how this is all supposed to work, as on Ubuntu Bionic (18.04), libpcl-dev is at version 1.8.x. TI claims Bionic is compatible with their ROS package though, which clearly states the 1.7.2 version requirement.

There may be some other problem preventing you from building their driver.

I'd probably still suggest to contact TI and ask them for support. It's their product after all.

In this part of the error message:

In file included from /usr/include/pcl-1.8

we see you have PCL version 1.8.x installed.

The versions of ti_mmwave_rospkg I can find online (such as radar-lab/ti_mmwave_rospkg and ibcn-cloudlet/ti_mmwave_rospkg), seem to suggest ti_mmwave_rospkg needs PCL version 1.7.2. See fi (from radar-lab/ti_mmwave_rospkg/CMakeLists.txt):

find_package(PCL 1.7.2 REQUIRED)

I'm curious how you got things to build on your system, as I would have expected a CMake error telling you that it can't find version 1.7.2 of PCL, and then aborts the build.

It's likely your compilation problem is caused by this version mismatch. You'll have to ask Texas Instruments about this, or fix the problem yourself.

Hello, The issue was resolved. It was a bug related to repository. They have cleared it and when updated building the package was successful. Thank you
