Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution|--- |INVALID --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- The explanations above are correct. We could do something here dependent on __cpp_inline_variables >= 201606, if that helps other compilers, but using _GLIBCXX17_INLINE isn't the right fix (that should always be defined when __cplusplus > 201402L, so if the Intel compiler is undefining it you should stop doing that, and work with us to support your copiler properly). I'd entertain patches to do that, but am unlikely top find time to do so myself.
