Error using dynare (line 229)DYNARE: preprocessing failed

Hi, everyone.

I found “An early 2007 gensys implementation” codes in one pdf file on the internet. Now I want to run it, but I don’t know how to do it. I had one basic .mod file and deleted everything in this file and copied the codes from the pdf and pasted to the empty .mod file. Now, when I run it it gives me an error:

Error using dynare (line 229)
DYNARE: preprocessing failed

What should I do?
Thanks.

Please provide the file you are talking about and the reference.

I want to run any of these codes from the website: https://sites.google.com/site/lkilian2019/textbook/code
(it is somehow not related to my initial question here, but anyway)
My main problem is that I don’t know how to run .m files.
We revised only how to run .mod files (with dynare) and my friend told me that I cannot use dynare in order to estimate .m file and there should be another way to estimate it.
Can you please help me? Please, explain which command should I give in order to run .m file.
Thanks.

Those are not Dynare files. They are simply Matlab files that you can run in Matlab like any other piece of code.
