macOS arm64 Debug build broken?

[robs]

Hello,

Thanks for the work to support CEF on the Apple Silicon (M1) processors.
Is it expected (or known) that it does not work in a Debug build?

1. Download the spotify build for arm64:
https://cef-builds.spotifycdn.com/cef_b ... 64.tar.bz2

2. Before expanding the archive you probably want to remove the quarantine xattr from the file:
xattr -c ~/Downloads/cef_binary*.bz2

3. Expand the bz2

4. Configure and build:

Code: Select all

cd cef...
mkdir build && cd build
cmake .. -G Xcode -DPROJECT_ARCH="arm64"
open cef.xcodeproj
build and launch Debug cefclient.app


It launches, but the window stays white. I see the following in the console:

Code: Select all

2020-12-07 10:39:32.075750-0500 cefclient Helper (GPU)[57258:13510473] [1207/103932.075262:ERROR:vt_video_encode_accelerator_mac.cc(515)]  VTCompressionSessionCreate failed: -12908
[1207/103932.075262:ERROR:vt_video_encode_accelerator_mac.cc(515)]  VTCompressionSessionCreate failed: -12908


When I launch in a Release build I don't see the above error in the console.

I'm running on an Apple Developer Transition Kit. macOS Big Sur 11.0.1. Xcode version 12.2.

Note, when I build with ninja, it crashes on launch with the crash reporting saying "Termination Reason: Namespace CODESIGNING, Code 0x2". I suppose I need to sign it, and Xcode does this automatically?

Thanks,
Rob

Yes, there appears to be a renderer process crash with the Debug build.

Thanks, would you like me to add a bug, or is this known?

You can leave it with me. I suspect it will be a Chromium issue.
