Hi @focalhot ,
which OS / golang version are you targeting?

[ghost]

@facchinm

go version go1.10.1 darwin/amd64
macOS 10.13.3

[facchinm]

Can you try exporting

export MACOSX_DEPLOYMENT_TARGET=10.9
export CGO_ENABLED=1

in the same shell before building?
It looks like that flag is supported by latest clang so maybe it's a go toolchain bug.
We are currently building with 1.8.3 (using osxcross for OSX build)

@facchinm It still does not work well.Same error.

[glowflame]

Any updates here? I'm having the same error:

go version go1.10.2 darwin/amd64
MacOS 10.13.2

I'm also getting an issue running go get github.com/arduino/arduino-create-agent both on my Ubuntu 18.04 and on a Docker container, both running go 1.8.7:

$ go version
go version go1.8.7 linux/amd64
$ go get github.com/arduino/arduino-create-agent
package math/bits: unrecognized import path "math/bits" (import path does not begin with hostname)

$ docker run -i -t golang:1.8.7 bash
root@ea8e1acf1b11:/go# go version
go version go1.8.7 linux/amd64
root@36835224d745:/go# go get github.com/arduino/arduino-create-agent
package math/bits: unrecognized import path "math/bits" (import path does not begin with hostname)

Any idea what it could be? This is the very first time I'm running Go so sorry if it's too much of a rookie mistake...

[facchinm]

I think latest master branch needs golang 1.10+ . @rsora can you confirm?

[rsora]

Confirmed, with dependencies managed with dep tool

My apologies for the lack of details in the README, I'll update the build instructions asap!

Upgrading to 1.10.5 did passed the initial problem but still getting:

$ go get github.com/arduino/arduino-create-agent

Package gtk+-3.0 was not found in the pkg-config search path.

I, and certainly more people on the community, would really appreciate if the build instructions were a bit richer... I'm willing to contribute writing documentation, debugging those issues and in any other way you think it's possible.

But I'm new to Go and since I am not able to "go get" the project, I'm a bit lost on where to start haha What would you suggest me to do? :)

[facchinm]

Hi @murilopolese , sorry for the lack of documentation. The problem is that every OS has different prerequisites due to the tray icon being OS specific.
Linux in particular requires libappindicator which has two (three) different names 🙂
The problem you are encountering can be solved by installing -dev packages, which provide all the needed headers to compile stuff against the library.

[murilopolese]

Thanks big time! I managed to build! ❤️ I made a small PR with updating the docs about the go version and dev packages as a way to say thanks!

All the best!

Thanks @murilopolese for your contribution. I'll go ahead and mark this ticket as 'closed' while we work on merging #273
