Hi,

I have not been able to get the expected result after compilation of the grammer file.I do not know what the problem is as I followed the steps carefully.

It gives this:

sample.grammar has 3 rules
sample.voca    has 6 categories and 18 words

 Now parsing grammar file
"rror:       Lexical mistake "
---
no .dfa or .dict file generated

Help will be appreciated.

Hi rovira74,

Are you running the mkdfa.pl script in Windows, Cygwin, or Linux?  Which version?  I tried it on Fedora FC6, and it seems to work OK.

It sounds like you might have extra characters in either your sample.grammar and sample.voca. 

It might also be a problem with using a Windows text file on Unix/Cygwin or vice versa (i.e. extra carriage returns or line feeds).  The "dos2unix" or "unix2dos" Linux/Cygwin commands can clear this up.

Hi ethan,

>how do you use the dos2unix and/or command?

From a Cygwin console on Windows, you should be able to use the "man" command to get documentation on any Cygwin command, like this:

 $ man dos2unix

$ man unix2dos 

(use the "q" to exit the man help page)

>if I use windows (vista) which one of the two should I use?

I can' t remember off-hand... I don't have access to a Windows machine right now -  try them both and see which works  :)

use the "cd" command to change directory to where your files are located, then execute the commands as follows:

  • dos2unix *.*
  • unix2dos *.*
This will convert all the files in the particular directory.

My version of Cygwin does not have a "man" page entries for these commands either.  Google brings up the following web pages:

Hi,

I am running the mkdfa.pl script in cygwin, and not been able to get either .dfa or .dict file generated.

It gives this error message:

$ ./mkdfa.pl ticket

ticket.grammar has 4 rules

ticket.voca has 9 categories and 18 words

---

Error: cannot open "ticket.dfa.tmp"

---

no .dfa or .dict file generated

 

I have already used the dos2unix command but it didn't fix the problem.

I'd really appreciate if someone could tell me how to fix this. Thanks.
