Thanks. I think I just found another solution (remains to be seen, currently compiling...). I simply do template<class S, class T> void apply_markers(S& sub_domains, T sub_domain) const; S happens to be a template type over T, but it's not necessary to write that out explicitly in the above function definition. -- Anders _______________________________________________ Mailing list: https://launchpad.net/~dolfin Post to : [email protected] Unsubscribe : https://launchpad.net/~dolfin More help : https://help.launchpad.net/ListHelp
