failing on OSX

[majulier]

I just installed 6.0.4_1 on a Mac/OSX. I get "Error starting ET process through ssh, please make sure your ssh works first" regardless of if I am trying to connect to localhost or a remote machine. If trying to connect to a remote machine I get "Connected to server but canonname is null somehow". If trying to connect to localhost I get "bash: line 1: etterminal: command not found" after entering my password.
The remote machine works fine. I can et to it from itself or another machine. This seems to be an issue on the Mac side or due to an interface incompatibility.

[ailzhang]

Hey @majulier what's the et version on remote machine?

[majulier]

etterminal is present if I invoke it from the command line.

[majulier]

version on linux box is 5.1.9

[majulier]

version on Mac is 6.0.4

[ailzhang]

Oh binaries across major releases are not compatible. So try upgrading your et on remote machine as well?

[majulier]

trying to update on the linux box... (presumably I have an issue with pthreads...)

"Sanitizers" provides a separate development package or SDK, be sure it has
been installed.

[ailzhang]

Oh I think 6.0.4 binary are already rolled out to yum and apt-get, is that not working?
But to answer your question above, I think cloning recursively might fix your problem.
git clone --recurse-submodules https://github.com/MisterTea/EternalTerminal.git

[majulier]

I'm on CentOS for the linux box. there isn't an "et" for "yum install et". Do you know the package name?

[ailzhang]

Oh sorry building from source is required on centos I think, did https://github.com/MisterTea/EternalTerminal#centos-7 help?

[majulier]

Interestingly, google kept taking me to:
https://eternalterminal.dev/download/

instead. That doesn't have the same info as your link above.

following the (better) instructions I got:

I happen to be on gcc 8.2.0, on an Aarch64 (ARM) system. When I installed ET originally everything was flawless. Since then, I've updated to gcc and had to reinstall on the Mac, which created the version incompatibility.

[majulier]

yum install libutempter-devel got one error out of the way. Now I'm seeing:

perhaps I'm running into an instance of: https://stackoverflow.com/questions/24813827/cmake-failing-to-detect-pthreads-due-to-warnings/25130590#25130590 ?

@majulier Try yum install protobuf-lite-devel protobuf-lite?
