Solution: This error comes when we customize the the cst_tokenstream.c file (inside $FLITEDIR/src/utils directory) to suit our need. To resolve this issue put original  cst_tokenstream.c run the make command inside $FLITEDIR/src/utils  directory. GO to $FLITEDIR directory, run make command here also.  now run sts command.

After runninng idx and voxdata command, replace cst_tokenstream.c with customized one, run the make command inside directory. GO to $FLITEDIR directory, run make command here also.  Now, proceed further
