Hi,

I am configuring my local environment on Windows 11 with WSL2 and Ubuntu.

I have installed foundationdb-client. I found some issues reported here

$ dpkg --status foundationdb-clients

And fdb bindings in go seem to be there after running go get:

$ go list  github.com/apple
/foundationdb/bindings/go/src/fdb
github.com/apple/foundationdb/bindings/go/src/fdb

I have also tried to install the bindings as explained here

$ ./fdb-go-install.sh install --fdbver 7.1.35
mkdir -p /home/manufog/go/src/github.com/apple

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by switching back to a branch.

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -c with the switch command. Example:

  git switch -c <new-branch-name>

Or undo this operation with:

  git switch -

Turn off this advice by setting config variable advice.detachedHead to false

But for some reason it looks like go cannot find the bindings module :thinking:

Do these errors ring any bells? Any help to get this fixed would be greatly appreciated :pray:

Ok looks like ubuntu default installation was missing libc6 and cmake.

After installing both I am getting this error:

$ make manager
go build -ldflags="-s -w -X github.com/FoundationDB/fdb-kubernetes-operator/setup.operatorVersion=4bcf4695bc8033ecffa7589cb0f41f832bf06a4b" -o bin/manager main.go

ok restoring go.mod and go.sum fixed it. Looks like I polluted the mod files during the troubleshooting.

Successful execution:

$ make manager
go build -ldflags="-s -w -X github.com/FoundationDB/fdb-kubernetes-operator/setup.operatorVersion=4bcf4695bc8033ecffa7589cb0f41f832bf06a4b" -o bin/manager main.go
