I have installed opam, and after this I can access ocaml, ocamlc, buildocaml successfully.
But I am reading Real World OCaml which is asking me to run a tool called corebuild.
I am not able to install (or run) corebuild.
If I search for sudo find / -name corebuild... I can see files like
/home/abhishek/.opam/repo/default/packages/core/core.109.38.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.42.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.35.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.34.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.47.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.41.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.32.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.37.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.45.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.36.00/files/corebuild
/home/abhishek/.opam/repo/default/packages/core/core.109.40.00/files/corebuild
But still then I don't know how to run this tool.
