MacOSX Mojave Panic #2465

Closed hippodribble closed 3 years ago

hippodribble commented 3 years ago

Describe the bug:

Unable to run any examples or fyne_demo in OSX Mojave 10.14.6

To Reproduce:

Steps to reproduce the behaviour:

  1. Install go, vscode with extensions, as well as fyne, fyne_demo
  2. Enter example code below into Visual Studio Code or text editor in folder
  3. Run go mod init github.com/whatever/stuff and go mod tidy in same source folder
  4. Try go run main.go -> panic
  5. go build completes normally, but executable does not run (same output)
  6. fyne_demo also does not start
  7. Code without fyne dependencies is working normally
  8. go.mod contains indirect dependencies - on Windows, it does not.

Terminal Output:

...etc

Example code:

package main

import (
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/widget"
)

func main() {
    app := app.New()

    w := app.NewWindow("Hello")
    w.SetContent(widget.NewLabel("Hello Fyne!"))

    w.ShowAndRun()
}

(or any code using fyne)

Jacalz commented 3 years ago

The indirect dependencies in your go.mod file are most likely because of a new feature (lazy module loading or pruned module graphs) in Go 1.17, not an issue with Fyne.

As for the actual panic, could you please share more of the stack trace? The part that is include above doesn’t contain the relevant information of the Fyne code running (just the runtime).

andydotxyz commented 3 years ago

AS this may relate to auto-graphics switching which we added in v2.1 work can you try the version v2.1.0-rc1 and confirm it is still an issue?

@Jacalz

Thanks for your help. Trace shown below.

I have fyne working on MacOSX 10.15.7 under clang 12.0.0, but not 10.14 under clang 10.

I'll upgrade to Big Sur, upgrade clang to 12+ and try again.

andydotxyz commented 3 years ago

Hmm, this is strange. It is almost certainly failing to create the OpenGL context. Can you please provide more information about your hardware configuration?

hippodribble commented 3 years ago

Andy

Macbook Pro 2017 Radeon Pro 560 4 GB

I just installed Big Sur and reinstalled vscode and fyne

I loaded this code from the Tour, which works on my Macbook Air under Catalina 10.15.7:

package main

import (
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/widget"
)

func main() {
    app := app.New()

    w := app.NewWindow("Hello")
    w.SetContent(widget.NewLabel("Hello Fyne!"))

    w.ShowAndRun()
}

It still won't run (nor will fyne_demo)Stack trace is:

WORKAROUND: compile on Macbook Air and copy to Macbook Pro. Code runs correctly.

andydotxyz commented 3 years ago

I think I understand. The fix that resolved auto-switching is in v2.1.0, but it is in the packager no the library. When you installed on a different computer you probably got the new one (check with fyne version). If you upgrade the cmdline tool on the computer that is not working (using go get -u fyne.io/fyne/v2/cmd/fyne) it should build and run correctly.

hippodribble commented 3 years ago

Thanks Andy

No luck, I'm afraid. I uninstalled the packages and the CLI application (even the demo), and reinstalled them all (packages and binary are now both v2.1.0). fyne version fyne cli version: v2.1.0 go mod init on the base example (window with a button) gives: module testfyne

go 1.17

go mod tidy then gives: module testfyne

go 1.17

It still fails to execute (building works, it just doesn't run). Whether I build and run, or go run, I get the same thing. If I create a binary on my Macbook Air and try to run that on the Macbook Pro, I also seem to get the same thing, viz

Perhaps it's the fact that I have a 2017 Mac with Big Sur. Mind you, it didn't work on Catalina either. A little frustrating of course.

I ran a diff on go.mod and go.sum from both Macs. They are the same.

I was able to go build . on both machines. The resulting file klengths were different:

MBP: 13226440 MBA: 13226672

The difference is 232 bytes.

Source code was:

package main

import (
    "fyne.io/fyne/v2/app"
    "fyne.io/fyne/v2/widget"
)

func main() {
    app := app.New()

    w := app.NewWindow("Hello")
    w.SetContent(widget.NewLabel("Hello Fyne!"))

    w.ShowAndRun()
}

If you have any suggestions as to other things I could try, I would certainly be grateful. I have been working through your book and creating custom widgets for displaying data as images, etc. I am hoping to compile for Mac and Win for folk at work.

Cheers

You seem to have helped narrow it down to a runtime issue - something about OpenGL. It seems not to be able to connect to your graphics card. Are you able to run any other OpenGL based apps? (google around for examples perhaps - not ones using material). Not sure how to start debugging the GL setup on macOS.

Thanks Andy

I was able to open .obj files in Clari3D, a free CAD viewer that uses OpenGL. I don't believe it uses Material.

Cheers

Thanks for this. I have one more thought. The GPU auto-switching config is part of the app metadata, so go run will not enable this. Can you please run fyne package (with the v2.1.0 at least version of fyne tool), then try executing the app by running open myapp.app (or double clicking the icon) instead of running it using the go commands. Hopefully this helps!

hippodribble commented 3 years ago

Thanks Andy

That worked. So I can just build and package.

I'll let you know if any more complex apps give a similar problem. I used the demo hello fyne app here. As it wasn't working before and is working now, it is a good result. Many thanks for your help.

This was a 2017 15" Macbook Pro, the one with the shitty keyboard. Maybe I am the only person with this problem.

Cheers

Glad it is sorted. Maybe we can find a way to message that this is a resolution for macOS developers that could hit it using go run
