Slow Dynare on Ubuntu 15.04

[vegard]

Hi,

I have a problem with a very slow Dynare running on Ubuntu 15.04. I think there is a problem with the mex compilation. When I run 'sudo dpkg-reconfigure dynare-matlab' i get the following error:

Does anyone know how to solve this?

What version of Matlab do you have? Matlab supports older versions of GCC so you need to use the version of GCC that conforms with your version of Matlab

[HoutanBastani]

Also the dynare version available on Ubuntu is sevral years old because it just uses the Debian package. It would be better for you to compile from source. It's rather simple:

Code: Select all

apt-get build-dep dynare
git clone --recursive https://github.com/DynareTeam/dynare.git
cd dynare
git checkout -b 4.4
./configure --with-matlab=/usr/local/MATlAB/R20XX MATLAB_VERSION=R20XX
make

I currently run R2014b. I will try a newer version of Dynare.

Thanks.

I installed the the latest version of Dynare and it solved the problem. Thanks.
