This system gives compiler no end of artifice (6)
I believe the answer is:
metric
'this system' is the definition.
(I have seen 'System of measurement' mean 'metric' so perhaps 'system' could also mean 'metric')
'compiler no end of artifice' is the wordplay.
'compiler' becomes 'me' (the person who is writing these clues).
'no end of' means to remove the last letter.
'artifice' becomes 'trick' (I've seen this before).
'trick' with its last letter taken off is 'tric'.
'me'+'tric'='METRIC'
'gives' acts as a link.
(Other definitions for metric that I've seen before include "Consisting of verses; pertaining to one system of measurement" , "Successor to imperial (system)" , "Relating to poetic rhythm" , "Relating to verse - based on the metre" , "Like the SI system" .)
