Hi, I have Ubunto 18.04 ROS Melodic during the compilation getting the following error

Hi, I think I've had errors like this in the past. A few quick questions:

• Is this a clean compile, or are you recompiling after changing something?
• Did you change anything in the protoc file?
• Do you have ccache installed?

i encounter this problem when i tried to compile it on ROS noetic Ubuntu 20.04. actually there isnt a directory called aslam/common, how can a fix it. i followed the setting procedure in your website.

@AcamelQ Ah, sorry, didn't see the issue earlier. So a clean compile?

• Did you follow this?
• If you run dpkg -l | grep protobuf on the terminal, what do you get?

That file aslam/common/id.pb.h is automatically generated by google protobuf. So it means that for some reason protoc is not running. Maybe there's an issue with how the dependency is set up.
