Installing Mariadb error

Learning

Hey folks,

I am trying to build ocaml-caqti to run the examples. When I run dune build I get an error for mariadb.
When I run opam install mariadb i get the following output:

~/git/ocaml-caqti master
❯ opam install mariadb
The following actions will be performed:
  βˆ— install mariadb 1.1.4

I have run opam update and opam upgrade. I have mariadb installed via brew.

Any suggestions on resolving this error would be greatly appreciated. Thank you.

Never used any of that but:

Are you sure you have that ?

> brew search mariadb

mariadb                                mariadb@10.1                           mariadb@10.4

mariadb-connector-odbc                 mariadb@10.3                           qt-mariadb

Perhaps mariadb-connector-c ?

Looks like i have the mariadb and mariadb-connector-c. I have unlinked them and relinked them as well.

dune-workspace.dev seems tested for 4.12.0 and not 4.12.1. Dont know if that matters.

(lang dune 1.2)

(context (opam (switch 4.12.0)))
(context (opam (switch 4.09.0)))
(context (opam (switch 4.08.1)))

; Earlier OCaml switches will fail to build caqti-driver-postgresql due to
; the version constraint on postgresql >=5.0.0; other packages should work
; down to 4.04.
(context (opam (switch 4.06.1)))
(context (opam (switch 4.05.0)))
(context (opam (switch 4.04.2)))

I don’t know how mariadb is looked up. Maybe try to issue:

export LIBRARY_PATH=/usr/local/lib:
export C_INCLUDE_PATH=/usr/local/include:

before opam install mariadb ?
