Is there one similar to this but that doesn't require your code to compile under Clang? I have plenty of projects at home that don't instantly work under Clang. So far, I've never seen any C++ language server that doesn't rely on Clang unfortunately.

Unlikely because GCC deliberately made it hard to reach into its internals for a long time. The only other implementation is the one by Microsoft based (presumably) on their C++ compiler.

There is a LSP in progress for clang C/C++.

I remember an old project to use the Eclipse CDT C++ support via vim instead of in the Eclipse IDE: http://eclim.org/index.html

I think there is/was some attempt to do it for emacs as well.

What are the usual culprits that prevent it from working under clang?

Clang doesn't support

    template<class ...Args>
    void foo(int x = 0, Args&&... args)

for example (default argument before variadic templates args).

Wow, I was going to guess that was illegal anyways, but cppref validates that behavior[0].
