*** Emacs

If you're using Emacs as your development environment just install =clangd= and =lsp=.

|

** Heads up for devs
|
||||
While you're working on *Serene* be mindful of:
|
||||
- In =DEBUG= mode we dynamically link against =libsan= due to the fact that we build the =libserene=
|
||||
as a shared lib by default. This means we need to =LD_PRELOAD= the =libclang_rt= before we run
|
||||
any executable. If you're using the =builder= script you're all set otherwise you can run an
|
||||
executable like:
|
||||
|
||||
#+BEGIN_SRC bash
|
||||
LD_PRELOAD=$(clang -print-file-name=libclang_rt.asan-x86_64.so) /path/to/executable
|
||||
#+END_SRC
|
||||
|
||||
* How to build
|
||||
In order to build for development (Debug mode) just use =./builder build= to setup the build and build
