AFAICT from the docs the following should compile:

#include

namespace icl = ::boost::icl;

void interval_set_intersects() { icl::intersects( icl::interval_set< int >(), 1 ); }

but I get a no match error:

gcc.compile.c++ bin/gcc-4.4.3/debug/src/sandbox.o src/sandbox.cpp: In function ‘void interval_set_intersects()’: src/sandbox.cpp:7: error: No match for ‘intersects(boost::icl::interval_set, allocator> &, int)’

Just a shot, but have you noticed the first argument is by reference, and you are passing a temporary? Does the following work:

{ icl::interval_set<int> iclset;

icl::intersects( iclset, 1 ); }

Good point but it doesn't change things.

Grrr, this is an error. bool intersects(..) and bool disjoint(..) do not compile as intended and documented for element_types and segment_types. Thank you for spotting this. I'm going to fix that. If you don't bother to burn up some time you can write a ticket but I will fix this anyway. Unfortunately it's tool late for 1.46 :( As a workaround we can fall back to using only containers as arguments for functions intersects and disjoint: icl::interval_set<int> iclset; iclset += interval<int>::right_open(1,5); icl::interval_set<int> one; one += 1; BOOST_CHECK(icl::intersects( iclset, one )); BOOST_CHECK(!icl::disjoint( iclset, one )); Regards, Joachim -- Interval Container Library [Boost.Icl] http://www.joachim-faulhaber.de
