Hi,
In its steps forward FreeBSD has moved to Clang 8.0 on the HEAD release,
soon to be followed on other releases. Also Boost on FreeBSD will soon
migrate to 1.70, but not clear how much fallout that'll generate.
And this Clang version complains about a protected destructor in Boost
code, which seems to be intentionally protected.
So getting Boost to fix this is probably not going to happen.
I now crudely fixed temporarily it by unprotecting the dtor in the boost
include, but can't ask other to do that.
So I need a dtor in this Temple class.
I tried all in cantations I could think of but apparently is my C++ foo
not enough.
Can somebody suggest a dtor? where I can't seem to get the class type
correct.
Or another way around this?
Thanx,
--WjW
