[DynareDev] Dynare compilation and flex

Dear all,

After an upgrade of debian testing (yesterday) I have been unable to compile dynare. The culprit seems to be the new version of flex (2.6.0-11). Houtan can you check if this is a bug in flex or if we have to change something on our side? I suppose you may have the same issue with homebrew...

For those who upgraded flex to 2.6.0-11 you will need to downgrade flex:

~$ sudo apt-get remove flex libfl-dev ~$ sudo apt-get install libfl-dev=2.5.39-8+b1 ~$ sudo apt-get install flex=2.5.39-8+b1

You should also (temporarily) prevent future upgrades for these packages :

~$ sudo apt-mark hold libfl-dev flex

If you did not upgrade debian, you may also want to apply the last step (until we understand the problem).

Best, Stéphane.
