I'm having issues getting a small spirit/qi grammar to compile. The build stack trace is fugly enought to not make any sense to me (despite some assertion_failed i could notice in there but that didn't brought much information)
the input grammar header:
inputGrammar.h
#include <boost/config/warning_disable.hpp>

using namespace boost::spirit::ascii;
//using namespace boost::spirit::arg_names;
namespace fusion = boost::fusion;
namespace phoenix = boost::phoenix;
using phoenix::at_c;
using phoenix::push_back;
template< typename Iterator , typename ExpressionAST >
struct InputGrammar : qi::grammar<Iterator, ExpressionAST(), space_type> {
InputGrammar() : InputGrammar::base_type( block ) {
tag = sp::lexeme[+(alpha) [sp::_val += sp::_1]];//[+(char_ - '<') [_val += _1]];
block = sp::lit("block") [ at_c<0>(sp::_val) = sp::_1]
>> "(" >> *instruction[ push_back( at_c<1>(sp::_val) , sp::_1 ) ]
>> ")";
command = tag [ at_c<0>(sp::_val) = sp::_1]
>> "(" >> *instruction [ push_back( at_c<1>(sp::_val) , sp::_1 )]
>> ")";
instruction = ( command | tag ) [sp::_val = sp::_1];
}
qi::rule< Iterator , std::string() , space_type > tag;
qi::rule< Iterator , ExpressionAST() , space_type > block;
qi::rule< Iterator , ExpressionAST() , space_type > function_def;
qi::rule< Iterator , ExpressionAST() , space_type > command;
qi::rule< Iterator , ExpressionAST() , space_type > instruction;
};
the test build program: i seems the build fails at qi::phrase_parse, i am using boost 1.43 and g++ 4.4.1

The attribute(s) always have to be passed as the last parameter(s) to the parse/phrase_parse functions. So you need to write:
bool r = qi::phrase_parse( iter , end , g , space, root );
Further, you can remove all semantic actions from your grammar if you add additional constructors to the ExpressionAST type:
template< typename Iterator , typename ExpressionAST >
struct InputGrammar : qi::grammar<Iterator, ExpressionAST(), space_type> {
InputGrammar() : InputGrammar::base_type( block ) {
tag = sp::lexeme[+(alpha)];
block = sp::lit("block") >> "(" >> *instruction >> ")";
command = tag >> "(" >> *instruction >> ")";
instruction = ( command | tag );
}
qi::rule< Iterator , std::string() , space_type > tag;
qi::rule< Iterator , ExpressionAST() , space_type > block;
qi::rule< Iterator , ExpressionAST() , space_type > function_def;
qi::rule< Iterator , ExpressionAST() , space_type > command;
qi::rule< Iterator , ExpressionAST() , space_type > instruction;
};
and
struct MockExpressionNode {
// ...
MockExpressionNode() {}
MockExpressionNode(std::string name) : name(name) {}
// ...
};
But even then it won't compile because the MockExpressionNode data structure is self-recursive. This can be fixed by either storing a vector of pointers (which requires to changethe grammar) or by using boost::recursive_wrapper.
