ClangComplete

Though, LSP has now been standardized by Microsoft, and the LLVM team created their own implementation, named clangd, which also has an associated VSCode extension.

Setup

You need to have Clang installed, and accessible via your path.

Compiler flags

Optional flags for Clang can be defined in a .clang_complete file at the root path of the project :

 -DDEBUG
 -include ../config.h
 -I../include
