make output redirection

I want to redirect the output and error stre开发者_如何学运维am 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

Should be

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

you can also just do:

make &> build.log

"&>" means send stdout and stderr to this file

Realize that this is a bit old, but here's one for posterity.

I often find it useful to pipe the stderr to a file:

make > error.log 2>&1

You can then open up the file in vim while passing the -q flag, this will allow you to rattle forward and backward along the list of errors.

vim -q error.log
