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
by
#include
#include #include #include . 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? * if it should work, what is still left to be included in my case?
It should work, but the savings in compile time will be minimal. If you want to reduce compile and build time, follow the example in the compiler tutorial from calc7 up. The trick is to modularize your grammars and put the definitions in separate cpp files (TUs). Regards, -- Joel de Guzman http://www.ciere.com http://boost-spirit.com http://www.cycfi.com/
