Build.md

* GCC 7.2 or higher (`optional,string_view` require libstdc++7 or higher)
* MSVC 2017 or higher (included with VS2017 Build Tools)
* On POSIX systems, either GNU make or Ninja (optional on other systems)
* Clang+LLVM headers and libraries
* Clang+LLVM headers and libraries, version >= 7 ([0.20181225.8](https://github.com/MaskRay/ccls/releases/tag/0.20181225.8) is the last release that supports clang 6)

## Initialization Options
Initialization options are defined in [config.hh](https://github.com/MaskRay/ccls/blob/master/src/config.hh).
Each language client may have its own way to specify initialization options.
Also, initialization options can be specified on the `ccls` command line using
the [`--init` option](#--initjson).

```elisp
(setq ccls-executable "/path/to/ccls/Release/ccls")

;; (setq ccls-executable "/usr/bin/ccls")
;; ;; Log file
;; (setq ccls-args '("--log-file=/tmp/ccls.log"))
```
A more flexible way is to leave `ccls-executable` unchanged (default: `ccls`) and create a shell wrapper named `ccls` that is in your `PATH`:
```zsh
#!/bin/zsh
#export CCLS_TRACEME=1 # if you want to debug ccls, stop it right after main() is called
#export LD_LIBRARY_PATH=~/llvm/Release/lib # if you link against shared library libLLVM.so, not statically
exec ~/ccls/Release/ccls --log-file=/tmp/ccls.log "$@"
```
You may leave `ccls-executable` unchanged (default: `ccls`) and create a [shell script wrapper](Install#shell-script-wrapper).

@ -58,11 +48,13 @@ Some common settings to lsp-mode lsp-ui and emacs-ccls:
When `M-x lsp` is invoked, projectile is consulted to locate the project root which determines the associated lsp-mode workspace.
If your project has subprojects, `(projectile-project-root)` may think files in the subproject belong to the child workspace, which is not desired. `touch .ccls-root` in the root directory to override projectile roots.
Read `lsp-project-whitelist lsp-project-blacklist` if you don't want to start ccls for some paths.
#### flycheck
If you are flycheck user, make sure ` (setq-default flycheck-disabled-checkers '(c/c++-clang c/c++-cppcheck c/c++-gcc))`, otherwise wrong error messages may occur.
flymake is used by default.
To use flycheck, `(setq lsp-prefer-flymake nil)`. You may also need `(setq-default flycheck-disabled-checkers '(c/c++-clang c/c++-cppcheck c/c++-gcc))` to disable other checkers.
