How to install corebuild in ocaml

Question

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.

You need to run opam install core to get corebuild .

More generally, you should look at the install instructions here , which will show you which libraries to install. Note that corebuild is a simple wrapper around ocamlbuild , and it assumes that you have core installed, and gives you the option of using it by default.
