Interesting to hear that C++ isn’t that well supported on OpenBSD. The story is quite the opposite with FreeBSD, where it’s really easy to use either clang or gcc. I usually spin up new jails to keep different installations sandboxed. CLion works quite nicely with most window managers on FreeBSD, but I rarely boot Xwindows these days and usually prefer to work with emacs inside tmux from the console.

C++ support is pretty good with base Clang 5, OpenBSD is using the libc++ standard library and libc++abi (FreeBSD uses PathScale's libcxxrt). The situation with debuggers is another story, the base version of gdb is outdated (GPLv2 version). The ports/packages version (egdb) has better support for things like C++, threads, but may lack other features. There is currently no support for the LLVM debugger, sadly.

  I wondered why he didn’t use LLDB; thanks.

My gut feeling is(was) that C++ is a first class citizen on OpenBSD. Its interesting having my beliefs challenged like this from someone so influential. The question becomes; if its not C++, then what is the first class citizen on OpenBSD. And if it is C++ then how do we improve support? Just going to ports seems like a poor answer.

    Sure, but is there a popular, modern C compiler out there that doesn't compile C++ as well? Clang, GCC, Intel, MSVC... all of them compile C++ as well as C. I don't think it's possible to have first-hand support for C and not C++ any more unless you ship your own compiler. It sounds like the issue here is that OpenBSD is shipping older versions of LLVM/Clang and GCC.

      Actually those C compilers you mention are implemented in C++, so yeah from that point of view you are right. I was just speaking from language point of view, without regard to specific implementations.

      OpenBSD's base ships the most recent LLVM and Clang (5.01), but there's no LLDB yet and gdb is outdated (6.3, the last GPLv2 version). He would have had a much better time using C99 than C++11, especially since he didn't want to install a newer gdb from ports.

  It's possible given his technical depth he was using more obscure C++ constructs which aren't as well supported. [1] http://madebyevan.com/obscure-cpp-features/ http://madebyevan.com/obscure-cpp-features/
