We are working on bringing Golang 1.21.X version to Toolbox. It will be available in a couple of weeks. 

Hi Sylvain,

you usually (but not always) can cross-compile Google Go from any other device. I compiled several projects on my Mac and used them afterwards on AIX. Of course it doesn't work if you bind to external AIX libraries or use CGO in your project.

Hi Andrey,

This is very interesting, thanks for your reply!

However, I never could produce XCOFF (AIX) binaries on ppcle (Ubuntu), only ELF... I'd really like to make it, but may need some guidance here!

Hi Sylvain,

as usual - "hello world" example ;-)

package mainimport "fmt"func main() {    fmt.Println("Hello world")}

The system is Ubuntu x86_64 and sorry, I have only Go 1.20.2 on it:

$ cat /etc/*releaseDISTRIB_ID=UbuntuDISTRIB_RELEASE=20.04DISTRIB_CODENAME=focalDISTRIB_DESCRIPTION="Ubuntu 20.04.6 LTS"NAME="Ubuntu"VERSION="20.04.6 LTS (Focal Fossa)"ID=ubuntuID_LIKE=debianPRETTY_NAME="Ubuntu 20.04.6 LTS"VERSION_ID="20.04"HOME_URL="https://www.ubuntu.com/"SUPPORT_URL="https://help.ubuntu.com/"BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"VERSION_CODENAME=focalUBUNTU_CODENAME=focal$ go versiongo version go1.20.2 linux/amd64

Compiling hello world:

$ go build -o hello$ GOOS=aix GOARCH=ppc64 go build -o hello_aix

Result:

$ file hello_aixhello_aix: 64-bit XCOFF executable or object module

Copy to AIX and execute there:

$ scp hello_aix aix:hello_aix                                                                  100% 3530KB  21.8MB/s   00:00    $ ssh aix#./hello_aixHello world
