running the app like always, but now I get: (attached screenshot)

Same issue on my side, but only on projects using cgo. This works as expected on non-cgo projects.

tzookb · 2024-09-24T20:05:47Z

I would say that I made it "work" by downgrading dlv to 1.21.2

rm -f $(which dlv)

./build-support/go/go1.21.0/bin/go install github.com/go-delve/delve/cmd/[email protected]

but now breakpoint are not stopping, as it says:

could not find file /xxxxx/src/go/example.com/contacts_interactions/server/contacts_interactions.go

hyangah · 2024-09-24T21:16:56Z

Can you try to run dlv command directly and see if it works?
I think something like

cd /xxxxxxx/connected_accounts/cmd/connected_accountsd
dlv debug ./main.go

cc @derekparker @aarzilli

tzookb · 2024-09-24T22:35:24Z

not sure if it worked or not :|

#:/ dlv debug ./main.go
Warning: no debug info found, some functionality will be missing such as stack traces and variable evaluation.
Type 'help' for list of commands.

(dlv)

derekparker · 2024-09-24T22:40:08Z

@tzookb was this using the latest version of Delve? This error message is unusual especially considering Delve is building the binary. The binary seems to be created without any debug information.

A few questions:

Are you using CGO? Are you disabling DWARF (debug info) generation in any C compilation unit?
Do you have anything nonstandard during your build process that could be stripping the debug information during a build?

tzookb · 2024-09-24T23:44:45Z

I just installed latest vscode-go, that installed latest dlv, as I don't want to jump hoops around versioning.

I tried to see what I can do here:
https://github.com/golang/vscode-go/blob/master/docs/debugging.md#starting-a-debug-session-fails-with

but I get the original error of the issue:

Failed to launch: could not launch process: could not read debug info (decoding dwarf section info at offset 0x0: too short) and could not read go symbol table (could not find rodata struct member

dlv (latest 1.23.1) debug errors now:

➜  connected_accountsd git:(master) ✗ dlv debug ./main.go

Warning: no debug info found, some functionality will be missing such as stack traces and variable evaluation.
could not launch process: could not read debug info (decoding dwarf section info at offset 0x0: too short) and could not read go symbol table (could not find rodata struct member)

we are using a this go version: go version go1.21.0 darwin/arm64

Are you using CGO? Are you disabling DWARF (debug info) generation in any C compilation unit?
- I don't think so, Ill verify
Do you have anything nonstandard during your build process that could be stripping the debug information during a build?
- Im passing the program file full path, so I assume the extension builds and runs the file by itself, I didn't pass any special flags

aarzilli · 2024-09-25T06:45:50Z

Could be a duplicate of go-delve/delve#3701, knowing whether you are using CGO would be important.

aarzilli · 2024-09-25T15:05:03Z

What about cgo? Does it use it? Also can you post the binary executable built with go build -gcflags='all=-N -l' ... somewhere?

dunglas · 2024-09-25T15:37:23Z

In my case, cgo is heavily used (and I haven't the problem on non-cgo projects) and I've the same problem when using the command line:

This looks to be the same issue as: go-delve/delve#1138 (comment)
However, I tried to upgrade delve and the other workaround and nothing fixes the issue in my case.

aarzilli · 2024-09-25T17:05:44Z

cc @cherrymui it could be that the problem that existed with custom clang toolchains now also affects the xcode toolchain.

dunglas · 2024-09-25T17:20:45Z

I also notified a weird issue that may, or may not be related.

Starting the program with go run main.go works, but building it with go build and then executing it fails with this error:

terminated by signal SIGKILL (Forced quit)

However, executing the binary that is killed through LLDB (lldb ./mybinary) surprisingly works.

dunglas · 2024-09-25T17:26:14Z

I figured out the issue on my side: it is because the project has toolchain go1.22.0 in its go.mod.
Setting the environment variable GOTOOLCHAIN to auto to force using the system installation fixes both Delve and go build. Thanks for your time and sorry for the noise.

Edit: the root of the issue was that ~/Library/Application\ Support/go/env was containing a GOTOOLCHAIN variable (I've no idea why, I probably messed it up at some point). Removing this file definitely fixed the issue.

tzookb · 2024-09-25T23:10:56Z

at least for me I noticed that for an app that include packages that needs "CGO_ENABLED" it fails with the mentioned error.

it depends on
https://github.com/confluentinc/confluent-kafka-go

aarzilli · 2024-09-26T04:49:29Z

@tzookb can you upgrade to go1.23 and see if the problem still reproduces?

tzookb · 2024-09-26T15:26:37Z

checked with 1.23
and Im able to run and debug 😮‍💨

aarzilli · 2024-09-26T15:29:24Z

I think this can be closed.

tzookb · 2024-09-26T15:43:03Z

do we have a suggestion for go 1.21?

findleyr · 2024-09-26T16:29:09Z

Thanks @aarzilli @dunglas and @derekparker for your help investigating.

do we have a suggestion for go 1.21?

@tzookb as Go 1.21 is not supported by the Go release policy, I don't think we'll be able to help. If you must use 1.21, your solution above (downgrading delve) may be necessary.
