Version of Delve is too old for Go version 1.20.0 (maximum supported version 1.19)

Question

When start debbugging session in GoLand I get this error:

WARNING: undefined behavior - version of Delve is too old for Go version 1.20.0 (maximum supported version 1.19)

I reinstall it with JetBrains Toolbox and didn't work. I uninstall it and install it manualy and didn't work!

The IDE maintainers say that GoLand didn't update delve when updating the IDE version in SOME CONDITIONS!

Have you tried installing a newer version of delve? – Hardwick

No, there is no doc on JetBrains to update it in GoLand. If you have a resource to do it please provide me with it. – Director

Please download EAP version of GoLand (jetbrains.com/go/nextversion). It contains the latest version of Delve. – Davedaveda

Thanks But, it is stable? – Director

It is in Beta right now, so pretty stable. Alternatively, you can update Delve using following workaround: youtrack.jetbrains.com/issue/GO-14287/… – Davedaveda

Answer 1

I was using GoLand 2022.3.2, recently 2022.3.3 was released and I update it to the latest version, and the issue was resolved.

I don't think it solves the problem entirely and I may hit it again in the future. So, I hope they fix it in a complete manner.

Answer 2

I found this workaround from the official issue.

1. Install dlv binary with go install github.com/go-delve/delve/cmd/dlv@latest
2. Set the dlv.path=<path_to_dlv_executable> under Help > Edit Custom Properties
3. Restart GoLand

It works for me.

Firstly install the latest version of delve based on the instructions here, https://github.com/go-delve/delve/tree/master/Documentation/installation

# Install the latest release:
$ go install github.com/go-delve/delve/cmd/dlv@latest

After installing the latest version of dlv, identify the path of the dlv executable file,

which dlv
# Output: /Users/<username>/go/bin/dlv

In your debug console check for the path that is used for running dlv /Users/<username>/Library/Application Support/JetBrains/IntelliJIdea2022.1/plugins/go/lib/dlv/macarm/dlv

Goto to the above path and follow the below steps,

mv dlv dlv.old # If the dlv is present 
ln -s /Users/<username>/go/bin/dlv dlv

Now you can rerun the application and you should be able to get the debugger working.

Answer 4

I solved this issue in this way:

go install github.com/go-delve/delve/cmd/dlv@latest

(first make a copy of the original dlv.exe)

copy '%homepath%\go\bin\dlv.exe' to 'C:\Program Files\JetBrains\goland-2022.1.4.win\plugins\go\lib\dlv\windows\dlv.exe' restart GolandIDE

Answer 5

You can either install the latest version of goland or upgrade only the dlv. For the latter, download source code from here and run go install pathToYourDownloadedPackage/cmd/dlv

Please read the post comments, there is no doc on JetBrains to update delve in GoLand. – Director

Answer 6

I was having the same problem. Updating the Goland version solved my problem.

Make sure you've fully updated your IDE by following these commands: Help -> Check for updates.

In ubuntu, if you install goland by jetbrains toolbox, you can upgrade goland dlv with following commands:

go install github.com/go-delve/delve/cmd/dlv@latest                     # download and compile latest version dlv
p=~/.local/share/JetBrains/Toolbox/apps/goland/plugins/go/lib/dlv/linux # goland dlv binary location
$p/dlv version                                # check older version                                     
mv $p/dlv $p/dlv.old && mv $GOPATH/bin/dlv $p # move to upgrade
$p/dlv version                                # check newer version

Answer 8

I have same problem, and I have solved it by replacing the DLV bound to Goland with a 1.8.0 support Golang 1.16 DLV version.

1. download an older dlv version supporting your golang version, such as: my golang is 1.16 and dlv use this delve1.8.0

2. complie dlv:

cd <downloadDir>/cmd/dlv 
go build

3. edit goland properties: Help > Edit Custom Properities..., and add

dlv.path=<yourPath>/cmd/dlv/dlv
