Hi,

I am searching for near bobs and putting them to

std::vector<Bob *> own_nearby;

then iterate over it and if the bob is soldier (and meets some other
requirements) I need to put it to

std::vector<Soldier *> defending_soldiers;

The relevant part of code is:

for (Bob * own : own_nearby) {
if (upcast(Soldier, ownSoldier, own)) {
if (ownSoldier->is_defending()){
defending_soldiers.back(ownSoldier);
}
}
}

But it complains during compilation:

 error: no matching function for call to 'std::vector<const
Widelands::Soldier*>::back(Widelands::Soldier* const&)'
       defending_soldiers.back(ownSoldier);

If I understand it correctly (if at all :) ) the upcast is making const
from soldier... how to circumvent it? defending_soldiers vector is to be
shortliving, immediately forgotten....

Ideas? :)
