Sorry, was wrong correction line. The right one is:

#if (!defined(BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK) \
  && !defined(BOOST_RESULT_OF_USE_DECLTYPE)) \
    || defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)

component spirit → fusion

Can I get a minimal reproducible code (or your keywords.cpp)?

BTW, I'm planning to remove fusion's result_of hacks and becoming SFINAE-friendly. It should fix the issue.

Thank you for the fast reply.

keywords.cpp was the one of the standard tests in spirit repository. Here is the direct link to github for this file: https://github.com/boostorg/spirit/blob/master/repository/test/qi/keywords.cpp

I've read previously about the plans for fusion's "sfinae-fiction" but I also read this will require to reimplement a lot of code in it. So it may be a very time consuming task, as far as I understand.

By now I had to fork fusion into my code, fix result_of.hpp inside and use BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK. I would appreciate any solution that will not require the fusion fork with my custom fixes inside.

milestone To Be Determined → Boost 1.60.0

OK, I overhauled fusion::fold and it should work with decltype based result_of.

Also, I tested qi/keyworkds.cpp (with BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK) and compiled it successfully.

I am able to compile keywords.cpp with your fixes and with BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK, thank you very match.

However, I was not able to compile it with BOOST_RESULT_OF_USE_DECLTYPE. What it the reason?

Could you please regenerate preprocessed files? There are some orphaned references to fusion::detail::result_of_with_decltype here https://github.com/Flast/fusion/blob/d3449ab5e58d68c2a54d588f3bded4c1dcb2d16e/include/boost/fusion/algorithm/iteration/detail/preprocessed/fold.hpp and in other files as well.

Preprocessed files make often pull-request a huge change and to be hard to review it. I'll open a additional PR which only contains preprocessed files after it is merged.

I'm not sure is the keywords.hpp aware SFINAE-friendly result_of?

Should have been fixed in https://github.com/boostorg/spirit/pull/256
