Ninja: fatal: chdir to '/ out / Release' - No such file or directory

Question

I get the source code (chrome) on

$ glient sync

Fulfilled the entire command request:

     - gclient config ......
  - GYP_GENERATORS ...
  - build/intall-build-desp.......
  - GYP_DEFINES....
  - etc...

but when I try to create a chrome reverse like this:

lolo@ssa-workstation:~/work$ ninja -C /out/Release chromedriver

I always get this message

ninja: Entering directory `/out/Release'
ninja: fatal: chdir to '/out/Release' - No such file or directory`

please, help?
