Trouble with installation: SuperCollider and emacs

[asheshambasta]

I'm facing 2 issues with installation;
I've cloned the repo. under /home/ashesh/.emacs.d/manual-install/scel

SuperCollider issues errors on startup:

I've changed ~/.config/SuperCollider/sclang_conf.yaml to the following:

includePaths:
    -   /home/ashesh/.local/share/SuperCollider/downloaded-quarks/Vowel
    -   /home/ashesh/.local/share/SuperCollider/downloaded-quarks/Dirt-Samples
    -   /home/ashesh/.local/share/SuperCollider/downloaded-quarks/SuperDirt
    -   /home/ashesh/.emacs.d/manual-install/scel/sc
excludePaths:
    []
postInlineWarnings: false

SuperCollider now errors on startup with:

Emacs .el files also fail to load

My emacs init file also now contains:

;;;;;;;;;;;;;;;;;;;;;
;; Super collider  ;;
;;;;;;;;;;;;;;;;;;;;;

;; emacs w3m support: needed for supercollider, for example. 
(use-package w3m
  :after (require 'w3m)
)
(setq browse-url-browser-function 'w3m-browse-url)
(autoload 'w3m-browse-url "w3m" "Ask a WWW browser to show a URL." t)
;; optional keyboard short-cut
(global-set-key "\C-xm" 'browse-url-at-point)

;; SC related emacs files.
(add-to-list 'load-path "~/.emacs.d/manual-install/scel/el")
(require 'sclang)

And during eval, I now get:

Any pointers?

I think the README is either outdated or unclear.

You need to build sc-el as part of the SuperCollider build process.

$ cd [your_sc_build_directory]
$ cmake .. -DSC_EL=ON
$ make
$ sudo make install

This converts sclang-vars.el.in to sclang-vars.el, filling in paths. Without that step, you'll have problems.

After installation, sclang-mode files are in /usr/local/share/emacs/site-lisp/SuperCollider/, so:

(add-to-list 'load-path "/usr/local/share/emacs/site-lisp/SuperCollider")
(require 'sclang)

Then M-x sclang-start at least boots the interpreter.

@jamshark70 thanks for the reply! Yeah, that seems to be the issue. I'm on Nix however, so I'll just need to adapt this a little bit, but it should work.
