Hello,
I like Qi, but the compile times are terrible sometimes. My example is similar to this in [1], but it needs 3x as much time to compile. I thought this problem might be omitted by including selectively what is needed. So I went into [1] and replaced
#include <boost/spirit/include/qi.hpp>
by
#include <boost/spirit/include/qi_action.hpp> #include <boost/spirit/include/qi_grammar.hpp> #include <boost/spirit/include/qi_uint.hpp> #include <boost/spirit/include/qi_char.hpp> .
I got far, but then, there comes up a long error message, beginning like in [2].
My questions are:
* is selectively including from "boost/spirit/include" supposed to work, or should this never be done?
Yes, it should work.
* if it should work, what is still left to be included in my case?
#include <boost/spirit/include/qi_operator.hpp> BTW, if you care about the compile time, there's Spirit X3 in develope which utilizes c++11/14 and it claims to compile faster.
