Installation instructions for CentOS7

Installation instructions for CentOS7

NicolasRouquette opened this issue 5 years ago · comments

Building ET on CentOS7 is tricky.

First, the cmake utility is too old (2.8) so we have to install cmake3 explicitly:

yum -y install epel-release
yum install cmake3

(found this tip here: https://www.heliocastro.info/?p=238#comment-5624)

Next, building failed:

It looks like you are missing gflags and protobuf. IIRC on centos the packages are google-gflags and protobuf-devel . Please add to the README so future people know how to compile on centos

Nicolas Rouquette · Answer 2 · Tue Apr 02 2019 00:26:24 GMT+0800 (China Standard Time)

@MisterTea Can you please be more specific about what you're suggesting?

Jason Gauci · Answer 3 · Tue Apr 02 2019 01:20:38 GMT+0800 (China Standard Time)

sudo yum install protobuf-devel protobuf-compiler gflags-devel libsodium-devel libutempter-devel

Then rerun cmake.

Nicolas Rouquette · Answer 4 · Tue Apr 02 2019 05:03:41 GMT+0800 (China Standard Time)

Thanks, that worked.

Unfortunately, I can't use et because our CentOS-based VM is in the GovCloud where we have a mandatory banner on login; so all I get is:

Error in authentication with etserver: Error:  Connection error communicating with et deamon: No such file or directory.
, please make sure you don't print anything in server's .bashrc/.zshrc

Jason Gauci · Answer 5 · Tue Apr 02 2019 05:05:29 GMT+0800 (China Standard Time)

That's fixed in master. What are you using for a client? On mac, you can "brew install --HEAD et" to get master branch

Nicolas Rouquette · Answer 6 · Tue Apr 02 2019 05:10:05 GMT+0800 (China Standard Time)

I'm running on Ubuntu 18.04 LTS

I followed these instructions:

sudo add-apt-repository ppa:jgmath2000/et
sudo apt-get update
sudo apt-get install et

Should I use something else?

Jason Gauci · Answer 7 · Tue Apr 02 2019 05:11:00 GMT+0800 (China Standard Time)

Yep, you should build from source using latest master to support logins with banners.

Argh... on ubuntu 18.04 LTS, I couldn't build:

sudo apt-get install cmake

then:

cmake ../

"Protobuf compiler version doesn't match library version 3.0.0"

That sounds bad. Can you run "ccmake ../" and see what the difference is between protobuf and protobuf compiler?

On a related note, the installation documentation on the main Download page https://eternalterminal.dev/download/ are out of date in respect to the instructions on https://github.com/MisterTea/EternalTerminal

Jason Gauci · Answer 12 · Tue Apr 23 2019 02:36:57 GMT+0800 (China Standard Time)

@NicolasRouquette were you able to get the protobuf issue resolved? It looks like compiling in centos works

Salem · Answer 13 · Tue May 14 2019 23:46:50 GMT+0800 (China Standard Time)

For what it's worth, the installation instructions now in the README were enough for me to get the service running on CentOS 7. My local client (mac osx) hangs still when trying to connect (in a hard, non-killzble way), and I'm not sure if that's related or not.
