Zdravim,

upravuji kod pro modelovani neuronovych siti jako v neokortexu a snazim se pridat podporu pro Clang.

Potreboval bych poradit s porovnanim templatu a namespace v C++.

Kod, o kterem mluvim je k nahlednuti zde: https://github.com/breznak/nupic/tree/compilation .

Zde je vystup pri prekladu s chybou:

V podstate navod na reseni je podle meho tady http://clang.llvm.org/compatibility.html#dep_lookup , ale nevim, jak ho pouzit pro tento pripad :)

Zatim jsem se ptal na ML (anglicky) http://lists.numenta.org/pipermail/nupic_lists.numenta.org/2013-June/000398.html , ale bez odpovedi..

Budu moc rad, pokud mi nejaky zkusenejsi C++ programator poradi!

Diky, Marek
