i'm new writing in arduino , trying program "ultimate robot kit blue". in uploading first motor test, error message keeps coming says:

avr-g++: error: missing filename after '-o'
exit status 1
error compiling.

i've been trying robot , running quite time , appreciated!

you have not installed library correctly or correct name.  however, did not post code , did not post complete message guessing.  not @ guessing.  please try again, following instructions follow.

to post code and/or error messages:

1) use ctrl-t in arduino ide autoformat code.
2) paste autoformatted code between code tags (the </> button)
     so can see , deal code.
3) paste complete error message between code tags (the </> button)
     so can see , deal messages.

before posting again, should read 3 locked topics @ top of programming questions forum, , links these posts point.

if project involves wiring, please provide schematic and/or wiring diagram and/or photograph of wiring.

good luck!
