And for those who think there's some malicious (as opposed to friendly) competition between the two projects: Steve Naroff was also instrumental (both technically and managerially) to get Steve Jobs to pay us to get Objective C++ working in gcc back in the NeXT days.
I think that’s a typo. Objective-C, as you may know, is about as old as C++ (Wikipedia says it’s from 1984 and C++ from 1985, but both were evolved over several years, so I wouldn’t categorically say Objective-C is older)
I think Objective-C++, basically an implementation of Objective-C that makes it possible to link with C++, must be from 2000 or later, but even a semi-exact date isn’t easy to find (probably in Clang’s release notes)
Yeah nowadays it is very hard to find anything about Objective-C++, even Apple has taken the documentation down, so only old timers still have some references.
Even the link I provided, who knows for how long it will still stay up.
No, that's LLVM. Clang was Steve Naroff's baby after he stepped down from managing the team.
