What did you do?

I'm trying to run gotip download but I get an error that is not very explicit.

./make.bash -v

...

Building packages and commands for darwin/arm64.
runtime/cgo: /Users/rleone/sdk/gotip/pkg/tool/darwin_arm64/cgo: exit status 2
go tool dist: FAILED: /Users/rleone/sdk/gotip/pkg/tool/darwin_arm64/go_bootstrap install -v std: exit status 1

What did you see happen?

I see that the process exit but I don't think gotip is successfully installed and I don't understand what the problem is.

What did you expect to see?

I would expect gotip to be installed or to have an explicit error

[mknyszek]

What gets printed if you run /Users/rleone/sdk/gotip/pkg/tool/darwin_arm64/go_bootstrap install -v std?

[mknyszek]

It seems almost like it's using your Go 1.25 compiler to build std erroneously, assuming that this is also what's going wrong in gotip. But it might not be, since the environment is probably slightly different. :/

Instead of using gotip, can you just confirm for me that the following steps work for you?

git clone https://go.googlesource.com/go
cd go/src
./make.bash

[remyleone]

nope this fails as well with:

go tool dist: FAILED: /Users/rleone/workspace/upstream/go/pkg/tool/darwin_arm64/go_bootstrap install -v std: exit status 1

[mknyszek]

Thanks for confirming -- so it's not related to gotip and environment management there.
