I am attempting to do “Matlab in the cloud with Dynare”. I’m not a Dynare expert, but quite comfortable with Linux systems and Docker.
Installing in cloud instances (CodeOcean-provided Matlab and Matlab-provided images) fails. There are two issues, outlined below, and I sketch out possible solutions, but they would need to be implemented by the package maintainers (Sebastien?)
Common to both
In both cases, the base OS is Ubuntu 20.04.
Installation of Matlab is not necessary - each image has Matlab pre-installed. However, the Matlab-provided image requires a login to a Mathworks account to actually run
matlab, even when running with a network license (not sure if this matters). The account is prompted when launching
In both cases, installation happens via
apt-get in the Dockerfile. (see follow-up message for details) Installing
dynare DEB package works (version is 4.6.0). It is the
dynare-matlab package that fails.
Issue one: non-interactive building fails, because the package interactively prompts for inputs (such as the Matlab location).
Possible solution: pass answers to those questions in via environment variables.
Issue two: when interactively installing (
apt-get dynare-matlab), answers are prompted, but installation fails with error message. See next message.
Help would be appreciated, because this would be quite convenient to have working!
RUN apt-get update \
&& apt-get install -y \
&& rm -rf /var/lib/apt/lists/*
Installation (interactive, not working)
docker run -it -p 8888:8888 --shm-size=512M myself/matlab2021a:2022-11-23 /bin/bash
then, as user
sudo apt-get update
sudo apt-get install -y dynare-matlab
Location of MATLAB installation(s): /opt/matlab/R2021a/
Authorized user for MATLAB:
Rename MATLAB's GCC libraries? [yes/no]
Prompt 1 is repeated:
Setting up matlab-support (0.0.21.1) ...
debconf: unable to initialize frontend: Dialog
debconf: (No usable dialog-like program is installed, so the dialog based frontend cannot be used. at /usr/share/perl5/Debconf/FrontEnd/Dialog.pm line 76.)
debconf: falling back to frontend: Readline
MATLAB interface configuration
The MATLAB interface needs to know where MATLAB is installed on this system. This can be specified as a single directory or, in case of multiple MATLAB installations, as a glob expression (any
expression supported by bash, including extended pattern matching operators).
If, for example, the MATLAB executable is installed in /opt/matlab76/bin/matlab, please enter "/opt/matlab76". If there are multiple MATLAB versions installed, you can enter "/opt/matlab*" or a similar
expression. Only matches that really contain a MATLAB executable will be considered. Therefore, a glob expression may match more than just MATLAB installation directories without negative side effects.
Location of MATLAB installation(s):
with same answer as before.
This leads to failure:
Setting up dynare-matlab (4.6.0+dfsg-2) ...
Building Matlab extensions (logfile at /tmp/dynare-matlab-mexbuild-1669224388.a98qMX7)
configure: error: MATLAB cannot be found
dpkg: error processing package dynare-matlab (--configure):

Not sure how to address this. One fix that was tried (no success)
ln -s /usr/local/bin/matlab /usr/local/bin/MATLAB
sudo cat /tmp/dynare-matlab-mexbuild-1669224534.4xLVQdb

I’m installing from source, but ran into problem there.
Most likely it’s because you’re running a too recent MATLAB version compared to the Dynare version (which is quite old). You should either upgrade to Dynare 5.3 or downgrade to MATLAB R2019b.
