The bug of Copter-3.3.3

When I make the example of RangeFinder in the folder “C:\pixhawk_toolchain\ardupilot-3.3.3\libraries\AP_RangeFinder\examples\RFIND_test”, there are some error like below


Is this the bug of Copter-3.3.3?
Anyone know about it?

Why no body answer me?

Your post has only 1 day, you need to wait, this is a volunteer forum support, not a paid one.

Now, can you explain what you want to know? Your question isn’t clear.

Thank you for your reply, and I was only in a hurry,
Some sensors have examples test program, I make the RFIND_test with Eclipse on windows like below to test my lidar

but the complization failed, I want to know is there any problem of the test program.

Thank you again for your help!

It is possible that examples don’t compile in that version of code. Not many people use them so sometimes they get outdated. You may try the master branch, although some examples also don’t work.
