Calling Go from a snap

[Lin-Buo-Ren]

Can this snap call the go binary installed on the system if it’s not a snap? I’m assuming it’s only yes if my snap is classic.

IMHO, correct.

@FelicianoTech

Can this snap call the go binary installed on the system via snap?

Nope.

@FelicianoTech

I can’t install Go within the snap because it will likely not be the same version of Go the user is developing with, which can impact the accuracy of running go test for their code.

AFAICT there’s two options:

• Make the snap classic confinement (NOTE: You must hack the dynamic linker environmental variable before calling any external commands, refer Snap confinement - #4 by lucyllewy and Subtle differences between devmode and classic confinement snaps )
• Make several Go runtime as content snaps and instruct users to connect the required Go runtime version to your snap, however in my knowledge such content snap doesn’t exist.
