opam install failing

[caseybasichis]

on ocaml 4.06.1 (and 4.07.0) I'm getting an opam install error:

edit: this is on a new xps15 with Mint 19... Maybe there is a package I'm missing?

I also get the error with: opam pin add postgresql git@github.com:mmottl/postgresql-ocaml.gittowards

@caseybasichis Could you please test the following command:

pg_config --includedir --libdir --version

It should display something similar to:

/opt/local/include/postgresql96
/opt/local/lib/postgresql96
PostgreSQL 9.6.9

[mmottl]

Also, please make sure the developer package containing the client C-library is installed.

[caseybasichis]

That was the issue:

'You need to install postgresql-server-dev-X.Y for building a server-side extension or libpq-dev for building a client-side application.'

sudo apt-get install postgresql-server-dev-10 solved it.

Thank you Markus!
