try these 2 idea's 
try putting the gears in without the engine running yes/no
then look check if you have a slave cylinder on the gearbox bell housing is it leaking .
get someone to WATCH the clutch push rod arm as you depress the clutch pedal ,if  No movement suspect (clutch master cylinder rubbers failed) 
if a cable clutch incorrect adjustment, or may have a  plastic ratchet  above the clutch pedal  with missing/stripped teeth
