Describe the bug

I have a module built by go plugin. And I want to load the plugin in my main module, and debug the main code in vscode using go extension.

However, I can always see below error when it goes to the line to load the plugin using plugin.Open():

plugin.Open("/path/to/my/plugin"): plugin was built with a different version of package runtime/internal/sys

While, if I build and run the code outside vscode on the same machine, it works w/o any problem.

As I know, usually, go plugin load failure like this is caused by plugin and main code using different golang release, GOPATH, etc. However, I've checked that they are all the same.

Does vscode-go support debug go code using go plugin? Any idea of how to troubleshoot this issue?

@morningspace does the program run without an error if you build/run the program outside vscode, and debug directly using delve? I see many open bugs and similar bug reports about plugin in upstream go project. So, maybe testing by eliminating the vscode or vscode-go is the first step to narrow down the scope of the problem.

golang/go#27751 (which uses module) and many others linked from there.

@hyangah Thanks for your prompt help... to try outside vscode and debug directly using delve is a really good idea. It can help me identify the cause further. I will circle back here when I have updates!

In my case, go test can run the program but when debugging with debug test in vscode, it will throw an error plugin was built with a different version of package runtime/internal/sys

Hi, I've managed to make it work after reading this. So, it's not an issue of vscode-go, but an "issue" of the upstream project delv. After I use -gcflags='all=-N -l' to build both the plugin and the main module, I can successfully debug it both by delv in terminal and vscode.

@jdu-mydevices You can have a try.

I'd be happy to close this issue if that works for others.
