8.3 Environment setup
We will begin our environment setup by building Clangd. Then, we will install VS Code, set up the Clangd extension, and configure Clangd within it.
8.3.1 Clangd build
It’s worth building Clangd in release mode, as we did for LLDB in Section 1.3.3, The LLVM debugger, its build, and usage. This is because performance is crucial in IDEs. For instance, Clangd requires building an AST to provide code navigation functionality. If a user modifies a document, the document should be rebuilt, and the navigation functionality will not be available until the rebuild process is completed. This can result in delays in IDE responses. To prevent IDE slowness in responses, we should ensure that Clangd is built with all the required optimizations. You can use the following project configuration command:
cmake -G Ninja -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=../install -DLLVM_TARGETS_TO_BUILD="X86" -DLLVM_ENABLE_PROJECTS="clang;clang-tools-extra...
