Hi,

#include <boost/spirit/include/qi_operator.hpp>

sadly, it did not. It did for the AST example, but it does not for mine I uploaded the code on github [3 (mostly) and 4]. Can you please help me with this file? Is there any generic approach if you hit such errors?

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.

I am really looking forward to this Regards, Johannes [3] https://github.com/JohannesLorenz/sca-toolsuite/blob/master/src/res/equation... [4] https://github.com/JohannesLorenz/sca-toolsuite/blob/master/src/res/equation...
