Hi Eric, hi all,
I'm getting the following errors when I try to compile the example in the atteched file.
test_proto_145.cpp: In function ‘int main()’: test_proto_145.cpp:91: error: no match for ‘operator<<’ in ‘emergency << 1’
I am using Boost 1.45 and GCC 4.4.5 This works fine in 1.46.0 and above.
Is there a patch ?
If upgrading Boost isn't an option, you have have a couple of other work-arounds. First, you can replace the proto/operators.hpp with the attached. Or, you can change your LevelGrammar to accept other terminal types, like: struct LevelGrammar : boost::proto::or_< LevelTerminals , boost::proto::terminal<boost::proto::_> , boost::proto::shift_left< LevelGrammar , boost::proto::not_< LevelTerminals > > > {}; HTH, -- Eric Niebler BoostPro Computing http://www.boostpro.com
