missing library error upon app launch

[mzimmers]

Hi -

I'm working through an (I2C) example in Molloy's book, and have come across a minor issue I'd like to resolve. When I load a program through Creator and begin debugging it, I get this error message:

Could not load shared library symbols for 7 libraries, e.g. /lib/arm-linux-gnueabihf/librt.so.1.
Use the "info sharedlibrary" command to see the complete listing.
Do you need "set solib-search-path" or "set sysroot"?

This library does exist on my Beaglebone Black. Any ideas why I'm getting this warning?

Also, I read here that this library is essentially deprecated, but I have libc.so.6 as well, so I'm not sure what I'm doing wrong here.

Thanks...
