Fix building using "make all" on macOS about eless HOT 12 CLOSED

That branch works.

On OS X it may be due to the cert store not containing the CA's cert.

Thanks. Do you want to hack build/setup-eless.el locally and see if forcing http instead of https helps?

These lines

Or may be launch Emacs -Q and manually eval the sexps in that setup file responsible for downloading those packages? I don't have a clue why the basic package installation would fail.. That package installation happens every time on Netlify each time https://eless.scripter.co/ deploys.

.. and here's the package installation on emacs 25.3 on Travis.. so what is so OS specific in that setup file ..

Found the problem: network-security-level was set to medium. This prompts one for confirmation before connections are made.

Setting this to low here fixed it.

Not sure if there are other solutions.

Interesting.. so you are prompted each time you install/upgrade a package?

from eless.

I use Cask so my installing is done outside emacs. In the cases when I do inside installing it's done via Try and yes, I'm prompted.

Well, I'm prompted for the host if I haven't been prompted in sometime. Not sure what that is. Seems to be weeks.

Found the problem: network-security-level was set to medium. This prompts one for confirmation before connections are made.

The default value of this variable (which got introduced in emacs 25.1) is 'medium, and it works fine i.e. I don't get any extra prompt on RHEL 6.6 (or any GNU Linux image on Gitlab Pages/Netlify/Travis). So it's likely that there's something special with macOS?

Setting this to low here fixed it.

Let me create a trial branch where I set that var to low only if the OS is macOS.

Please try this branch: https://github.com/kaushalmodi/eless/tree/macOS-lower-network-security

from eless.

This too merged into master.
