dynare4.4.3 + octave 4.0.0 + Xubuntu 16.04 LTS

[computable]

I am using Xubuntu 16.04 LTS and installed dynare and octave to run some DSGE models, using "sudo apt-get install octave" and "sudo apt-get install dynare"

Unfortunately I am hitting an error immediately as I try to run the tutorial files here: http://www.dynare.org/documentation-and ... t/tutorial

When trying to run "example1.mod" I get an error.

Here is my entire octave session, with errors:

I've tried a few other examples with similar results.

I googled the error messages and found this post:

- "dynare4.4.3 + octave 4.0.1+ windows10:" viewtopic.php?f=1&t=8286

It refers to this issue on github, which appears to *just* have been closed earlier today: https://github.com/DynareTeam/dynare/issues/1113

Does this appear to be the same problem? If so, do we know when it might be fixed on Linux?

Thanks!

Dynare 4.4.3 only supports Octave 3.8.1. That is why you are experiencing the problems. The unstable version supports 4.2.1. The problem is that the mex-files have to be built against the Octave version you are using. If you scroll down on https://github.com/DynareTeam/dynare you will see the description on how to build Dynare from source on Linux.

Update: here are the steps I ran to get Dynare running on my machine, using info from the link provided above. The "$" indicates this was executed on the linux command line, and the ">>" indicates this was executed on the octave command line:


$ sudo apt-get install build-essential gfortran liboctave-dev libboost-graph-dev libgsl0-dev libmatio-dev libslicot-dev libslicot-pic libsuitesparse-dev flex bison autoconf automake texlive texlive-publishers texlive-extra-utils texlive-formats-extra texlive-latex-extra texlive-fonts-extra latex-beamer texinfo texi2html latex2html doxygen pstoedit epstool xfig gnuplot
$ sudo apt-get install octave
$ cd ~/workspace # on my machine. You can install wherever you want, just adjust the "addpath" below.
$ git clone --recursive http://github.com/DynareTeam/dynare.git
$ cd dynare
$ autoreconf -si
$ ./configure
$ make
$ make html
$ octave
>> addpath ~/workspace/dynare/matlab
>> cd examples
>> dynare example1.mod

This should run the example.

Everything appears to be working. A few examples I've found elsewhere have issues, but I will post separately.

Thanks!
