Cross compiling from macOS to linux but my app doesn't work on linux

Hello all,

I am trying to build my app on my mac for linux by running this command while in the my app directory that has a main:

env GOOS=linux GOARCH=arm GOARM=7 go build

The build process goes okay,

I did make it make sure it is executable by running this command:

chmod +x app

Once I get it to the linux server and run it I get:

-bash: ./app: cannot execute binary file: Exec format error

I have Go 1.7.0

Any one have any idea what I am doing wrong?

There are a couple more options needed to make it truly static and runnable:

env CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -installsuffix cgo

So this would work? I didn’t no if the last part cgo was required?

env CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -v

UPDATE: sorry I was half asleep when posting, I missed the -a flag in the command.

here is a great article about dockerizing a go application, if you skip down to the compile section you will see the full command needed and a full explanation of what the flags are doing.

hope this can help :slight_smile:

Are you in fact deploying to an ARM box…?

I agree with @calmh, make sure your target machine is in fact an ARM box.

Here’s a list of possible enironment variables to use: $GOOS and $GOARCH environent variables

I have a:
Ubuntu 16.04.1 x64

So you want GOOS=linux GOARCH=amd64.


Fixed the problem. My server was not an ARM:

This command worked just fine:

env GOOS=linux GOARCH=amd64 go build

Sorry everyone i am super new at deployment.
