However, I guess most warnings triggered by GCC 4.8's `-Wunused-local-typedefs' (and hence `-Wall') option(s) are coming from Milena's concept checking statements located in milena/mln/core/concept/. I'll try to address this issue later (I just opened a ticket about it: https://trac.lrde.epita.fr/olena/ticket/296). Meanwhile, you can pass `-Wno-unused-local-typedefs' to g++ to get rid of these warnings. -- Roland Levillain EPITA Research and Development Laboratory (LRDE) 14-16, rue Voltaire - FR-94276 Le Kremlin-Bicêtre Cedex - France Phone: +33 1 53 14 59 45 - Fax: +33 1 53 14 59 22 - www.lrde.epita.fr
