Wrong CGG expansion of BOOST_ATTRIBUTE_NODISCARD when in -std=c++98 mode #336
Comments
Apologies for the long delay! This appears to be deliberate - Can you explain what issue this is causing? |
No apologies needed :-) I see otherwise: https://godbolt.org/z/P4dnd4T8q |
It's not supported on functions pre-c++11 even if __has_cpp_attribute indicates it is supported. Also update test case. Fixes #336.
Confirmed, works on classes but not functions. |
Perfect, thank you! Will keep an eye to this so that I can drop my workaround when your fix gets to master. |

-std=c++98
),BOOST_ATTRIBUTE_NODISCARD
wrongly expands to[[nodiscard]]
