Unable to compile for armhf on Raspberry Pi 3B

[bizi-betiko]

Since there's no arm binary already uploaded I tried to compile from source on a Raspberry Pi 3B running Raspbian Stretch where the repo go version is 1.7.4. I set $GOPATH to a home subfolder and run "go get -u github.com/tanaikech/goodls" as the manual suggests but I get

package google.golang.org/api/transport/http/internal/propagation: no buildable Go source files in /home/kostis/GoLang/src/google.golang.org/api/transport/http/internal/propagation

So, is there a way to build for armhf? Is perhaps a higher Go version required for this source code? Or perhaps a binary could be uploaded for armhf?

I was able to compile it under go version 1.9.7. Here is the instruction:

Get into the golang container:

docker run -it --rm --name goodls -e GOOS=linux -e GOARCH=arm -e GOARM=5 golang:1.9 sh

Then downgrade urfave/cli to the version that supports go v1.9:

go get -v github.com/urfave/cli
#ignore the error and run this:
cd /go/src/github.com/urfave/cli
git checkout v1.20.0
go build

Now we can install and compile the project:

go get -v github.com/tanaikech/goodls
cd /go/src/github.com/tanaikech/goodls
git checkout v1.2.3
go build

Once it's done check the compiled binary (goodls):

# ls -alh

drwxr-xr-x 2 root root 4.0K Dec  3 19:40 images

Now copy the binary to the host machine:

docker cp goodls:/go/src/github.com/tanaikech/goodls/goodls .

@tanaikech could you add the arm builds, please?

[tanaikech]

Thank you for your support. Unfortunately, I have no information about "the arm builds". This is due to my poor skill. I deeply apologize for this.

[karser]

@tanaikech I'm sorry, I didn't mean/intend to offend you but either I don't understand why did you answer me with sarcasm?
I shared instructions which solve this ticket and suggested that you add the ARM build support.

[tanaikech]

Thank you for your support. I deeply apologize for my poor English skill. I don't mean to hurt your feeling. Unfortunately, I cannot understand about what you want. Because I have no information about "the ARM build". The reason that I cannot understand about your replying is due to my skill. So I thought that I have to apologize for this.

[karser]

I see, there is no problem.
What I mean is to add goodls_linux_armv7 and goodls_linux_armv8 builds in here:

I think these parameters should work:

#build for ARMv7
GOOS=linux GOARCH=arm GOARM=7 go build
cp goodls goodls_linux_armv7

#build for ARMv8
GOOS=linux GOARCH=arm64 go build
cp goodls goodls_linux_armv8

[tanaikech]

Thank you for replying. I could understand about your proposal. So I added them to here. Could you please confirm it?

[karser]

Yes, it works, thank you! This issue is 100% resolved
