Error Running example1.mod

Installation
#1

Hi,

I’m new to Dynare and I downloaded it following the directions here https://github.com/DynareTeam/dynare on my Ubuntu 16.04 machine. When I try to run the example1.mod file, Matlab finishes preprocessing and I get the following error message.

The class ‘dates’ is used in its own class definition as a base class, property value, or attribute
value. This is not allowed.

Error in global_initialization (line 408)
options_.dataset.firstobs = dates();

Error in example1 (line 24)
global_initialization;

Error in dynare (line 267)
evalin(‘base’,fname) ;

I’ve searched online but cannot find anyone else with a similar error message. Is there something obvious that I am missing or does anyone know how to fix this? Thank you in advance.

Which version of Dynare did you in compile and install ? The stable version ?

Best,
Stéphane.

#3

Originally, I had the stable version, I believe. I just uninstalled Dynare and then reinstalled it using the unstable version and it works fine. Thank you for your comment!

Continuing the discussion from Error Running example1.mod:

Good morning,

I have just installed Dynare 4.6.2. and I get the same error krdoty mentioned 3 years ago. I also have version 4.5.2. in Dynare folder, but I deleted all paths of this older version from Matlab. I would like to keep the older version, because some of my codes do not work with the newest. The code I’m working with now produces the crash with a message about hessian_eq_zero not existing if I use the older version. A bug indicated in the FixedBugs for 4.6.2. I use Windows10.

    Using 64-bit preprocessor

The class 'dates' is used in its own class definition as a base class, property

Can I solve this? Thank you so much!

What is the output if you type into Matlab after the crash

which dates

?

#6

which dates
C:\dynare\4.6.2\matlab\modules\dseries\src@dates\dates.m % dates constructor

#7

Did you try


?

#8

Are you asking me whether I removed all 4.5.2 path entries in Matlab paths? Yes, I did. But I kept the older version in my computer. If I change directory or uninstall previous Dynare version, the ‘dates’ error disappears…

#9

What do you mean with

?

#10

If I move folder 4.5.2. from c:\Dynare to another folder in my computer (a part from removing the path to it in Matlab), then the problem is gone. Only 4.6.2. is now inside c:\Dynare.

#11

But that means that for some reason, you did not properly remove the path in Matlab. Only be moving the folder does Matlab not detect it.
