Nathan,
Thanks for the help. I was finally able to link my static library with my
module but now I'm again getting an undefined symbol error but this time on
my own module's methods.
I can't seem to get away from this problem.

FreeLingTokenizer is my class, but I'm not sure why now it can't find its
symbols.
Here is my binding.gyp file:
{
'targets': [
{
'target_name': 'freeling',
'type': 'loadable_module',
'product_extension': 'node',
'product_prefix': '',
'include_dirs': ['.','/home/roy/freeling/free3/include'],

['OS=="linux"', {
'libraries': ['/home/roy/freeling/free3/lib/libfreeling.so'],
}],
],
'sources': ['freeling.cc', 'freeling_tokenizer.cc', 'freeling.h',
'freeling_tokenizer.h'],
},
],
}
