Re: [Boost-users] [Spirit] Semantic actions (binary parser) - user error or bug?

2011/5/1 Hartmut Kaiser Semantic actions in Karma are supposed to _supply_ the attribute value to generate output from. Therefore your start rule needs to be written as:

   start = big_dword >> big_dword[_1 = ref(temp)];

I believe it was the Qi part (use %= instead):

    start %= big_dword >> big_dword [ref(temp) = _1];

Doh! Sorry for that. I should have read your code more carefully. Regards Hartmut --------------- http://boost-spirit.com
