node-gyp unable to cross compile for ARM processor

[Pavi]

Hi i wrote my binding.cc and binding.gyp for my ARM library,

I compiled and i always see the below error,

bash-4.1$ sudo /home/pavincoll/Downloads/node-v0.8.0/deps/npm/bin/node-gyp-bin/node-gyp configure build

[sudo] password for pavincoll: 

gyp info it worked if it ends with ok

gyp info using node...@0.5.2

gyp info using no...@0.8.0

gyp info spawn python

gyp info spawn args [ '/home/pavincoll/.node-gyp/0.8.0/tools/gyp_addon',

gyp info spawn args   'binding.gyp',

gyp info spawn args   '-I/home/pavincoll/workspace/aqstub/src/build/config.gypi',

gyp info spawn args   '-f',

gyp info spawn args   'make' ]

gyp info spawn make

gyp info spawn args [ 'BUILDTYPE=Release', '-C', 'build' ]

But the Library is a ARM compatible binary.

The config.gyp is always ,

  "target_defaults": {

    "cflags": [],

    "default_configuration": "Release",

    "defines": [],

    "include_dirs": [],

    "libraries": []

  },

  "variables": {

    "host_arch": "ia32",

    "node_install_npm": "true",

    "node_install_waf": "true",

    "node_prefix": "",

    "node_shared_openssl": "false",

    "node_shared_v8": "false",

    "node_shared_zlib": "false",

    "node_use_dtrace": "false",

    "node_use_etw": "false",

    "node_use_openssl": "true",

    "strict_aliasing": "true",

    "target_arch": "ia32",

    "v8_use_snapshot": "false",

    "nodedir": "/home/pavincoll/.node-gyp/0.8.0",

    "copy_dev_lib": "true"

  }

Were you can see Target_arch as "ia32"

Please let me know how should i cross compile node-gyp for an ARM processor

I have a script which sets all the Variables pointing to the ARM File system and Compiler to ARM.

Run node-gyp like this:

$ node-gyp --arch arm configure build # or just 'rebuild'

You shouldn't have to run it as root, by the way.
