How a project is meant to be compiled to run on the brick?

[basharov]

I know I can set flags to configure target architecture for a compiled app.
I want to develop on my main Mac machine, then compile and transfer compiled files into the brick.

What options should I use to compile for EV3 on a Mac?

[kortschak]

GOOS=linux GOARCH=arm GOARM=5 go build in the project directory will leave an arm5 ELF executable that will run on the EV3 in the project dir (the GOOS var would not need to be set if compiled on a linux machine).
