Cant compile example "record.ino" & other 'receiving' examples

[caliban17]

The example sketch rawRecv.ino compiles & runs fine, as do the various 'sending' examples, but When I try to compile the example record.ino for my Nano ,on the arduino IDE (1.81) get these errors:

I'm sorry but I cannot re-create your problem. I do not have an Arduino nano available however I can do a compile without uploading using Ctrl-R command. I was able to successfully compile for Nano using either the 328 or 168 processors. On the 168 I get a warning that we've nearly used up all available memory that I don't get any compile errors. I too am using Arduino IDE 1.8.1 on a Windows 10 PC. Just to make sure I was really using the right version of my own code, I archived my own files, downloaded everything from GitHub and try to recompile again. I still can't re-create your errors. I welcome anyone else's suggestions.

Issue solved. Thanks for your time. I re-downloaded the library, and then discovered that I had originally installed it in the arduino IDE library rather than my sketchbook library. With it installed in the correct place, the sample sketches compiled fine.
