Hi, I’m trying to get SCALE to work but I’m so confused by what they mean by PATH and I’m stuck.
https://github.com/spectral-compute/scale-docs/blob/master/docs/manual/how-to-use.md
I’m at the CMAKE step.
This is the official guide I’m following. I do understand what they mean by SCALE_PATH though as that is clearly explained but PATH is just very vague to me or I’m just misunderstanding it completely.
So I don’t know how much you know about the shell, but the way that the linux command line works is that there are a set of variables, called environment variables, which dictate so me behavior of the shell. For example, $PATH variable, refers to what directories to search through, when you try to execute a program in your shell.
The documentation you linked, wants you to create a custom shell variable, called SCALE_PATH, consisting of a folder path, which contains the compiled binaries/programs of scale you want to run.
This command:
export PATH="${SCALE_PATH}/bin:$PATH"temporarily edits your PATH variable to add that folder with the scale programs you want to run to your path, enabling you to execute them from your shell.
