Hi,
Don't know whether this is a boost-thing or C++ ... hope to put the
problem the right way.
Anyway, I have a tuple:
//! tuple of
typedef boost::tuple Proxy;
and a map like
//! map of
typedef std::map ProxyLT;
Now,
ProxyLT proxies;
proxy = boost::tuple(some string id, some
double, some character);
// pushing this tuple into the map/vector construct
proxies[some other string id].push_back(proxy);
And now I would like to sort these vectors within the map vector by
vector according to the double in the tuple. For this I have the
function (within a header file):
inline bool proxy_gt(Proxy first, Proxy second) {
return (first.get<1>() > second.get<1>());
}
and then the actual sorting:
for (yamas::ProxyLT::iterator pit = proxies.begin(); pit !=
proxies.end(); pit++) {
sort((*pit).second.begin(), (*pit).second.end(), proxy_gt);
}
Problem is that g++ keeps telling me
/usr/include/c++/4.4/bits/stl_heap.h:180: error: must use '.*' or '->*'
to call pointer-to-member function in '__comp (...)', e.g. '(... ->*
__comp) (...)'
when 'sort' is called.
Whatever I do to the inline function - I cannot solve this problem. Any
hints?
TIA
Cheers
Christian
