Help building from source on Ubuntu 16.04

[Paul L]

I keep running into the following error when trying to 'sudo make install':

What should I do?

You could try to replace the quoted https: tag with a simple http: one. Circumventing trying to establish a secure connection to the github server, which a certain program version does not support on your machine. Or try to update libcurl to the latest version.

Hi Paul

That's weird, I've got an ubuntu 16.04 box here and I've never seen that
issue. Can you tell us what version of CMake you're running?

Cheers,
Ben

Hi Ben,

I'm running Cmake version 3.5.2.

[Ben Swift]

Ok, great. And what's the output of curl --version ?

I just realized a mistake on my part. I originally attempted to install Extempore via linuxbrew, but ran into some problems, then decided to build from source. I believe it installed it's own copies of cmake, curl, and openssl. I just got around to removing those now. That may have been why I was receiving this error. I'll post another reply after attempting to compile again.   

[Ben Swift]

Ah, yeah. Is extempore still in linuxbrew? I really should take that
out, I haven't been maintaining that for ages. Thanks for the heads up,
and sorry about the confusion.

Yes it is. It compiled correctly after removing those linuxbrew packages. Also, I would suggest including 'sudo make install' in the one-liner build commands. I forked the project and am about to make a pull request. Thanks again for helping me through this problem!
