@dah33 Thanks for the report. Can you please try debugging with dlv to see if the problem is reproducible with dlv?

$ dlv debug
(dlv) b main.main
...

dah33 · 2021-12-01T18:18:25Z

Looks very broken:

(dlv) b main.main
Command failed: location "main.main" not found
(dlv) funcs
(dlv) sources
(dlv)

If I remove the glfw.Init() code and replace with say fmt.Println("hello, world") then it works as expected:

(dlv) b main.main
Breakpoint 1 set at 0x312aa6 for main.main() c:/users/danho/onedrive/documents/projects/nes/test/foo.go:5

     6:         fmt.Println("hello, world")
     7:         //glfw.Init()
     8: }
...

So it seems like my code is silently breaking the command line debugger?

hyangah · 2021-12-01T23:54:57Z

Assuming you installed all the libraries required to correctly use glfw,
can you build the program with the following command and share the compiled binary here for inspection?

go build -gcflags='all=-N -l'

Since glfw involves cgo and non-Go code heavily, it can be an issue in go compiler or delve.

dah33 · 2021-12-02T09:08:14Z

Here you go: https://1drv.ms/u/s!Aj6uwC1FRxANhroUVDQr8P_--LR8RQ?e=uiJraB

hyangah · 2021-12-05T04:53:11Z

@dah33 Thank you so much for sharing the binary. I see some compile units from c99/C11 with DWARF5.
I am guessing go-delve/delve#2786 and golang/go#49590 are relevant. I hope you have a better luck if you try go1.18 and the dlv built from the master. (cc @aarzilli @thanm)

btw I was curious so I tried to reproduce the issue from my windows box today, but failed to reproduce it using the example repro case. Skimming through the debug info, I see @dah33 and I used different mingw installation (mingw-w64-crt vs
mingw-w64) and my binary didn't include DWARF5 at all. 🤷🏽‍♀️

annomel · 2021-12-05T21:38:15Z

@hyangah I think you are using older mingw (msys2). I could debug in msys2 before but after updating to msys2-x86_64-20210725 I got into the same situation as go-delve/delve#2786.

hyangah · 2021-12-05T23:54:40Z

@annomel Of course, toolings in my mingw-w64 installation is older than mingw-w64-crt so it generates DWARF4 not DWARF5. The culprit is delve and the std library delve depended on didn't handle DWARF5. It's delve and go's issue, so I am closing it. Until then, use old toolings, or try delve built from the master branch with the Go built from tip.
