Hi , I tried to build the pkg but i get this error

Hmmm have never seen this before. Are you sure you checked out the right branch of voxblox and have you tried a clean rebuild of your workspace?

Hi,
Thank you for responding.
Yes, I have followed your suggestions and ensured that I have checked out the correct branch of voxblox (dynablox/release). I also performed a clean rebuild of the workspace. I still get the same error while building the dynolbox,

Hi @nivand ,

Unfortunately we are not able to reproduce your problem on a clean install. Are you sure you use dynablox/main without any additional changes and your compiler supports C++17? Alternatively, you can try to make sure Eigen is found correctly by adding eigen_catkin to the package.xml of dynablox/dynablox_ros.

Hi, Thank you for your response. Upon further investigation, I discovered that the issue was indeed related to the compiler not supporting C++17. After reinstalling the compiler with C++17 support, everything is now functioning correctly. I appreciate your assistance and suggestions.

Great to hear that your issues were resolved!
