Problems Downloading LedControl in Version 18

I just downloaded V-18 . . . now downloading LedControl has problems. When I try to complie the unzip . . . I get a "can not find file" error . . . where do I put it??? there is no ...hardware\libraries directory. Second, if I path to my location and compile I get a whole string of complie errors???

o: In function __static_initialization_and_destruction_0': C:\DOCUME~1\GREGBO~1\LOCALS~1\Temp\build2527318750577765040.tmp/LED_MATRIX_TEST.cpp:18: undefined reference toLedControl::LedControl(int, int, int, int)'

Hi, Arduino V18 looks for 3'rd party libraries (like LedControl) in a subfolder of your sketchbook directory named 'libraries'

So if your sketchbook dir is for instance : C:\DOCUME~1\GREGBO~1\sketchbook you install (unzip in this case) the in C:\DOCUME~1\GREGBO~1\sketchbook\libraries


Thanks Eberhard . . . helped alot!
