make output redirection

Question

I want to redirect the output and error stream of make command to file.

The following command

make 1>&2 ~/tmp/build.log

throws the following error

make: Nothing to be done for `/Users/m/tmp/build.log'.

EDIT:-

Tried

make 2>&1 ~/tmp/build.log

and

make ~/tmp/build.log 2>&1

which gave the same above error message.

I am using mac-leopard os
