delve: no such file or directory

Hello Brandon,

Can you share the Dockerfile configuration or a link to the project?

Hi Daniil, I posted up a quick goland project on https://github.com/bsnuggs1/remoteGoTest.  With this example, you should be able to see the same scenario where remote works if you use Run, but you get the "no such file or directory" when you try to use the Debugger.  

I also included the configurations that I used.

Thanks for looking into this!

Hello,

Will it work if you use golang image instead of golang-alpine?

Please see attached screenshot.

Thanks Daniil, that did the trick!  Admittedly, I am confused though...  I thought that the delve executable was transferred to the container, why is alpine usage a problem?  Also, the blog post, https://blog.jetbrains.com/go/2021/04/30/how-to-use-docker-to-compile-go-from-goland/, also uses alpine.

Hmm, perhaps I may have spoken too soon.  I noticed that this did indeed work for the simplified scenario, but when I tried using golang for the larger scenario, I get a different error where it seems that delve is timing out:

Debugger finished with the exit code 0

Goland will wait about 30 seconds before it gives up waiting for dlv.  I'm still investigating this, but I am curious if it has something to do with the dlv version.  As I understand, Goland 2022.3 uses Delve 1.9 and I'm curious about what happens if I force it to use 1.20 instead.

I get a different error where it seems that delve is timing out:

Is there a chance to share a reproducible example? Will it work in the same way with enabled Build on remote target option?

Thanks for spotting that out! We will update the blog post because alpine is different than other Linux distributions. Delve nowadays requires libc6-compat library to use, but it is not included by default in the image.

So, you can add RUN apk add --no-cache libc6-compat entry in Dockerfile or use a non-alpine image.

I am having a similar issue trying to run my debugger on the latest Go image…

Hi Himynameischaseiwearsocks, please share your Dockerfile.
