How to convert node-waf wscript to node-gyp binding.gyp

Question

I am writing a C addon for nodejs, and I can compile and create my module with node-waf without any problem. But I need to use node-gyp and when I try to build the module using node-gyp build I get the following error (node-gyp configure finishes successfully):

gyp info it worked if it ends with ok
gyp info using node-gyp@0.9.5
gyp info using node@0.8.23 | linux | ia32
make: Entering directory `/root/src/...'
gyp info spawn make
gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]

I guess that my problem could be caused by the difference between my wscript and binding.gyp. Does anybody know how to convert this wscript to binding.gyp?

import Options
from os import unlink, symlink, popen
from os.path import exists

srcdir = "."
blddir = "build"
VERSION = "0.0.1"

def set_options(opt):
  opt.tool_options("compiler_cxx")

def configure(conf):
  conf.check_tool("compiler_cxx")
  conf.check_tool("node_addon")
  conf.env.append_value('LINKFLAGS', 
     [])

def build(bld):
  obj = bld.new_task_gen("cxx", "shlib", "node_addon")
  obj.target = "mymodule"
  obj.source = "mymodule.cc"
  obj.cxxflags = ["-D_FILE_OFFSET_BITS=64", "-D_LARGEFILE_SOURCE",
        "-I/root/src/../api"]
  obj.lib = []

def shutdown():
  if Options.commands['clean']:
    if exists('mymodule.node'): unlink('mymodule.node')
  else:
    if exists('build/Release/mymodule.node') and not exists('mymodule.node'):
      symlink('build/Release/mymodule.node', 'mymodule.node')

and my current binding.gyp is:

{
  "targets": [
    {
      "target_name": "mymodule",
      "sources": [ "mymodule.cc" ],
     }
    ]
}

If you think that the problem is caused by something else (other than config file), your idea is welcome.

The answer is:

{
  "targets": [
    {
      "target_name": "mymodule",
      "include_dirs": "/root/src/../api",
      "sources": [ "mymodule.cc" ],
     }
    ]
}
