no matching function for call to boost::algorithm::split
Hi, I'm trying to compile the following code with g++, but it generates an error. It compiles fine in VC8. typedef vector<string> to_t; to_t to; split(to, row.f(2).s(), is_any_of(",")); error: no matching function for call to 'split(main()::to_t&, std::string, boost::algorithm::detail::is_any_ofF<char>)' /usr/include/boost/algorithm/string/split.hpp:143: note: candidates are: SequenceSequenceT& boost::algorithm::split(SequenceSequenceT&, RangeT&, PredicateT, boost::algorithm::token_compress_mode_type) [with SequenceSequenceT = main()::to_t, RangeT = std::string, PredicateT = boost::algorithm::detail::is_any_ofF<char>] Does anyone know what I'm doing wrong? $ g++ -v Using built-in specs.

Hi, I'm not sure. The code snippet you sent seems fine, so maybe the problem is elsewhere. I would check includes and namespaces. Regards, Pavol. On Tue, Mar 14, 2006 at 09:17:18PM +0100, Olaf van der Spek wrote:

Ok, I see the problem now. You cannot pass a temporary value into the split algorithm. The reason for this comes from a possibility to store result in a container of iterator_range's. In other word, the result will be just a reference to the input. So to workaround your problem, simply create a local variable, that will hold the input.
