Hi, i tried to write a grammar with ast tree generation and had problems using the gen_pt_node_d directive. It turned out that i had to patch spirit/core/scanner/scanner.hpp to get it working. This is the grammar i'm writing: http://www.threedeevee.com/VRMLGrammar.h I changed one initializer of a constructor of template-class scanner_policies in spirit/core/scanner/scanner.hpp of spirit v1.8.1 (v1.8.2 has the same declaration). This is the old declaration: template <typename ScannerPoliciesT> scanner_policies(ScannerPoliciesT const& policies) : IterationPolicyT(policies) , MatchPolicyT(policies) , ActionPolicyT(policies) {} changing the MatchPolicyT initiatlizer makes the above grammar work: , MatchPolicyT() I found this by just tracing error messages, I don't have enough insight into the code to tell whether there is a better solution. It would be nice if someone could either tell me that this wasn't necessary, or maybe add this patch to the code base if useful.
