linking problems

[Andreas Stolcke]

Where you able to build the standard "ngram" program in SRILM
without problems?  If so the problems you are having now
are most likely due to a discrepancy in the compiler or linker 
flags used.

Record the command line flags used in SRILM building and linking.
Then use the exact same options when compiling and linking your own 
program.
