Norm attaining operators and simultaneously continuous retractions

A compact metric space S is constructed and it is shown that there is a bounded linear operator T : L1 [0,1] -► C(S) which cannot be approximated by a norm attaining operator. Also it is established that there does not exist a retract of L°° [0,1] onto its unit ball which is simultaneously weak* continuous and norm uniformly continuous.
