Unable to make on Ubuntu 18 LTS

When trying to make on Ubuntu, I get these errors:

libc6-dev is installed.

Any advice?

You don't have a compiler installed on your system. For Debian-based systems like Ubuntu, install the build-essential package.

Thanks. You're correct, my bootstrap didn't have build-essentials, but after installing it we're still stuck.

Something still being missing makes sense.

I can compile it as shown in the Dockerfile, so I can maybe copy it from there (or just run it in Docker). It's a fun little program and I'm thinking of running it on lots of IoT devices, some of which don't meet Docker system requirements, though.

Do dice copying it from the Dockerfile. I get -bash: ./endlessh: No such file or directory when running the file, even after giving it execute permissions.

If you copy the executable from the Docker image you have still the issue that you are still missing some system libs to run it. I got it running on Ubuntu 18.04.5 LTS with on the latest commit installing build-essential and running make install but I don't know if it helps you.

You might be missing the package libc6-dev. Install it and give it a try!
