Re: [libextractor] OLE2 problem while using libextractor library

[Christian Grothoff]

I suspect that somehow the "HAVE_GSF" directive is not set when extractor.c 
was compiled (check the config.h file generated by configure).  Looking at 
the configure scripts (m4/abi-gsf.m4), I think that there is a bug which 
means that HAVE_GSF would NOT be set if something else Gnome'ish was detected 
on your system.  

Patch:

 if test "x$have_gsf_gnome" = "xtrue" ; then
        abi_gsf_message="yes, with GNOME support"
+        AC_DEFINE(HAVE_GSF, 1, [Have gsf])
 else if test "x$have_gsf" = "xtrue" ; then
        abi_gsf_message="yes, without GNOME support"
         AC_DEFINE(HAVE_GSF, 1, [Have gsf])

I've fixed the problem in SVN.  As a work-around, you can also load the ole2 
plugin by hand (as you do with extract's -l option below). You can do this in 
your own C code using EXTRACTOR_loadConfigLibraries.

Best regards,

Christian
