JSGF Sphinx using Python

[Loc Le Duc]

Hi

I want it to use a simple grammar(JSGF) in Spinx using Python. So I'm flowing this example:
https://github.com/cmusphinx/pocketsphinx/blob/master/swig/python/test/jsgf_test.py

But I got a following output in terminal:

INFO: ngram_search_fwdflat.c(157): fwdflat: min_ef_width = 4, max_sf_win = 25
INFO: jsgf.c(706): Defined rule: PUBLIC <house.command>
INFO: jsgf.c(706): Defined rule: <house.control>
INFO: jsgf.c(706): Defined rule: <house.device>
INFO: jsgf.c(706): Defined rule: <house.place>
Segmentation fault (core dumped)</house.place></house.device></house.control></house.command>

And i found the suggestion in this topic:
https://sourceforge.net/p/cmusphinx/discussion/help/thread/d5e1a902/

After i follow the topic, i got another error:

ERROR: "jsgf.c", line 910: Failed to open etc/grammar.jsgf for parsing: No such file or directory
Traceback (most recent call last):
File "example_1.py", line 19, in <module>
decoder = Decoder(config)
File "/usr/local/lib/python2.7/dist-packages/pocketsphinx-0.0.8-py2.7-linux-x86_64.egg/pocketsphinx/pocketsphinx.py", line 228, in init
this = _pocketsphinx.new_Decoder(*args)
RuntimeError: new_Decoder returned -1</module>

I'm sure that i have the file etc/grammar.jsgf which i create with a text document.
I have attached all results in the terminal of 2 case in this link:

Please help me to sort out the issue.

Thanks and Regards,

Thank you Nickolay, I had found the solution for the issus.
I follow this web (Finite State Grammars)
http://www.speech.cs.cmu.edu/15-492/homework/hw2/
After i convert the grammar file grammar.gram to grammar.fsg. I change the config in the code from:

   config.set_string('-lm', 'etc/dkmt_1.lm.DMP')

to

   config.set_string('-fsg', 'etc/grammar.fsg')

And the issus is solved.
