Hi Sébastien,
Slicot library is still not used in the estimation dll...
I downloaded succesfully the version 5 of Slicot this morning (currently Dynare distributes version 4). On Slicot's web site the library is still presented under a Gnu GPL licence. I will contact the authors next week to see if they plan to change the licence...
Yesterday you told me that it was not possible to change a GPL licence, because anyone can fork... So I guess that it is not an issue if we distribute old versions of Slicot, even if they choose another licence for the next versions (>5).
Best, Stéphane.

#194: Clarify Slicot licensing terms ----------------------------+----------------------------------------------- Reporter: sebastien | Owner: george Type: bug | Status: new Priority: critical | Milestone: Component: Estimation DLL | Version: Keywords: | ----------------------------+----------------------------------------------- Currently Dynare (unstable) distributes its own copy of libslicot (www.slicot.org). It is used in the Kalman Steady State DLL (at least).
As of July 15, 2011, it is no longer possible to download libslicot from its website. It says that the library is currently undergoing a relicensing.
We need to clarify this with Slicot authors to see if we can continue distributing it with Dynare.

Yes, we can still distribute old versions of Slicot under the GPL. However this may become a problem over time if the code is not supported. So it is yet unclear if this is really an issue on the long term, it depends on our ability to maintain the old code.
Hi
I do remember that Stephane planned to use Slicot for a new version of Kalman and/or Riccati (see enclosed email) but I do not know how far that work went along its implementation and I am not aware if Slicot library is already being in use in Dynare - i.e. I have not used it and I do not think it is used in C++ Estimation DLL and I do not know why if we need to distribute it with Dynare.
PS: We however have a fast Riccati implementation in Matlab used in Partial Information estimation and that can also be rewritten in C++ easily.
Best regards
George

This is not an issue as long as the codes are doing what they are asked to... But I will contact the authors next week.
Best, Stéphane.
So it is yet unclear if this is really an issue on the long
