[Boost-users] [Q] boost::spirit BOOST_FUSION_ADAPT_STRUCT error

16 Jun 2009

      Hello, I am attempting to parse

FuncName(arg1,arg2,... argN)

with Spirit, such that args are saved in a vector
and func name is saved into a funct_nm

I am just in the beginning of this (I have not learned yet how
to construct a grammar that allows comma delimited args within braces )

But running into a compilation error

on line

    (std::string, funct_nm)

within
BOOST_FUSION_ADAPT_STRUCT

I am using mini_xml1.cpp as an example

Would like to ask for help/pointers to resolve it.
I want to mention that my project on boost 1.38 and also includes
json_spirit which uses
( I am guessing the 'classic version' of spirit).

thank you in advance,
Vlad
