Re: [libextractor] OLE2 problem while using libextractor library

[sunilp]

Hi Christian,

 Well thanks first of all for your prompt reply.
 I applied the patch & compiled libextractor again. I checked out the
config.h file. Now it does set HAVE_GSF.

 EARLIER i had to use "extract -l libextractor_ole2 sample.doc" to get
metadata out of office files, But now it works
 if I just give
                                     "extract sample.doc"

But as earlier said when I use the libextractor library it does'nt give any
output, though it works for all other file types.
  
my sample code just contains following lines:
                     EXTRACTOR_ExtractorList *extractors =
EXTRACTOR_loadDefaultLibraries();
                     EXTRACTOR_KeywordList *keywords =
EXTRACTOR_getKeywords(extractors, argv[1]);
                     EXTRACTOR_printKeywords(stdout,keywords);
