boost-spirit

I'm in the progress of writing a compiler for a subset of Java, using boost::spirit , for lexing and parsing. During compilation of the lexer/parser phase, the compiler consumes 1.6GB of RAM ( g++ (GCC) 4.8.1 ), this is not an issue however, as there's plenty of memory on this machine. What is an issue however, is that when the compiler is done, and the assembler starts running ( GNU assembler (GNU Binutils) 2.23.52.20130604 ), it crashes with; as: build/src/ast_generate.o: too many sections (33098) /tmp/cc0ZyvKK.s: Assembler messages: /tmp/cc0ZyvKK.s: Fatal error: can't write build/src/ast

How can I match utf8 unicode characters using boost::spirit ? For example, I want to recognize all characters in this string: $ echo "На берегу пустынных волн" | ./a.out Н а б е р е гу п у с т ы н н ы х в о л н When I try this simple boost::spirit program it will not match the unicode characters correctly: #include <boost/spirit/include/qi.hpp> #include <boost/spirit/include/support_istream_iterator.hpp> #include <boost/foreach.hpp> namespace qi = boost::spirit::qi; int main() { std::cin.unsetf(std::ios::skipws); boost::spirit::istream_iterator begin(std::cin); boost::spirit::istream_iterator

I am writing a parser for quite complicated config files that make use of indentation etc. I decided to use Lex to break input into tokens as it seems to make life easier. The problem is that I cannot find any examples of using Qi error reporting tools ( on_error ) with parsers that operate on stream of tokens instead of characters. Error handler to be used in on_error takes some to be able to indicate exactly where the error is in the input stream. All examples just construct std::string from the pair of iterators and print them. But if Lex is used, that iterators are iterators to the

I am a beginner in using boost spirit Say that I have the following code that parse a simple arithmetic expression with variables: #include <boost/config/warning_disable.hpp> #include <boost/spirit/include/qi.hpp> #include <boost/variant/recursive_variant.hpp> #include <boost/variant/apply_visitor.hpp> #include <boost/fusion/include/adapt_struct.hpp> #include <boost/spirit/include/phoenix_function.hpp> #include <boost/foreach.hpp> #include <iostream> #include <string> namespace client { namespace ast { struct nil {}; struct signed_; struct program; typedef boost::variant< nil , double , boost:
