Description jonas.licht 2023-04-05 08:57:35 UTC 
To bootstrap golang version 1.20 at least Go 1.17.13 is required. https://go.dev/doc/go1.20#bootstrap

So trying to build go-native-1.20.1-r0 fails with:
| DEBUG: Executing shell function do_compile

The bootstrap mechanism seems to use the same PV when building go so it's not clear how you are encountering this problem. Can you explain how to reproduce the issue in detail?

Did you have some e.g. docker environment for a yocto example build to demonstrate the issue?

If I look into the go-native_1.20.1.bb it says in it's comment to first build go1.4 as the bootstrap version [0].
Buildroot is encountering some simualr error [1].

However, you can avoid to build you native go with the bootstrapping version by using the go-binary-native recipe.
Therefor I need to set PREFERRED_PROVIDER_go-native = "go-binary-native"

Movign to unassigned. Jonas, you want to work on this go for it.

I think the best solution would be to build the go-native directly with gccgo.
But this will require at least gcc version 12 and this will limit the supported Ubuntu version to 22.04 and above.

Another way could be a multistage bootstrapping, so building some intermediate version. But I think this will be a never ending storie.

We deleted the 1.4 recipe so this is no longer a valid bug.
