GUI hangs (no windows) when bitcoin-qt runs on macOS Big Sur, and it was compiled with depends (Qt 5.12)

hebasto commented at 1:09 pm on March 13, 2021: member

On macOS Big Sur 11.2.3 (20D91):

0% xcrun --show-sdk-version
111.1

When bitcoin-qt is compiled with depends, no window is shown.

That was not the case before bumping Qt version to 5.12.10. See https://github.com/bitcoin/bitcoin/pull/21376#issuecomment-795379418

I scratched it a bit. Looks like a problem with the Cocoa integration plugin as dereferencing of the QGuiApplicationPrivate::platformIntegration() pointer causes the EXC_BAD_ACCESS error.

Probably, it’s an upstream bug.

UPDATE:

Case A (SDK 11.1)

system: Big Sur 11.2.3 (20D91)

0% xcode-select --print-path    
1/Library/Developer/CommandLineTools
2% xcrun --show-sdk-path
3/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
4% xcrun --show-sdk-version         
511.1
6% make C depends
7% CONFIG_SITE=$PWD/depends/x86_64-apple-darwin20.3.0/share/config.site ./configure
8% make
9% src/qt/bitcoin-qt -regtest -printtoconsole

The client runs but the GUI hangs – no window is created.

Case B (SDK 11.1 compiled on Catalina, tested on Big Sur)

build system: Catalina 10.15.7 (19H524) + Xcode 12.4 (12D4e)

 0% xcodebuild -version
 1Xcode 12.4
 2Build version 12D4e
 3% xcode-select --print-path
 4/Applications/Xcode.app/Contents/Developer
 5% xcrun --sdk macosx --show-sdk-path
 6/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX11.1.sdk
 7% xcrun --sdk macosx --show-sdk-version
 811.1
 9% make C depends
10% CONFIG_SITE=$PWD/depends/x86_64-apple-darwin19.6.0/share/config.site ./configure
11% make
12% src/qt/bitcoin-qt -regtest -printtoconsole

Everything works just fine.

test system: Big Sur 11.2.3 (20D91)

The binary compiled on Catalina has been moved to Big Sur.

0% ~/Downloads/bitcoin-qt -regtest -printtoconsole

The client runs but the GUI hangs – no window is created (the same behavior as in the case A).

Case C (SDK 10.15.6 from downloaded Xcode 11.7)

system: Big Sur 11.2.3 (20D91)

 0% sudo xcode-select --switch ~/Downloads/Xcode_11.7/Xcode.app
 1% xcode-select --print-path
 2/Users/hebasto1/Downloads/Xcode_11.7/Xcode.app/Contents/Developer
 3% xcrun --show-sdk-path
 4/Users/hebasto1/Downloads/Xcode_11.7/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk
 5% xcrun --show-sdk-version         
 610.15.6
 7% make C depends
 8% CONFIG_SITE=$PWD/depends/x86_64-apple-darwin20.3.0/share/config.site ./configure
 9% make
10% src/qt/bitcoin-qt -regtest -printtoconsole

The client runs but the GUI hangs – no window is created (the same behavior as in the case A).

Xcode 10.3 and older (SDK 10.14.6) does ~~not~~ work on Big Sur at all. (see https://developer.apple.com/documentation/macos-release-notes/macos-big-sur-11_0_1-release-notes)

But building depends fail:

Case D (SDK 10.14.6 from downloaded Xcode 10.3)

build system: Big Sur 11.2.3 (20D91) + Xcode 10.3 (10G8)

0% xcodebuild -version
1Xcode 10.3
2Build version 10G8
3% xcode-select --print-path
4/Applications/Xcode.app/Contents/Developer
5% xcrun --show-sdk-path
6/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.14.sdk
7% xcrun --show-sdk-version
810.14
9% make -C depends native_ds_store

The last command fails (looks like an infinite loop).

@fanquake

FWIW, the build on your qt_5_15_2_rebased branch fails as well, unfortunately.

hebasto commented at 10:04 pm on March 15, 2021: member

Qt 5.12 docs define supported build environment as Xcode 10 (10.14 SDK).

My attempts to use downloaded Xcode 10.13 on Big Sur failed.

Confirming this issue on macOS Big Sur 11.2.2 and SDK 11.1, I get a bunch of warnings similar to this (if helpful)

0ld: warning: direct access in function 'QMetaTypeIdQObject<QWindow*, 8>::qt_metatype_id()' from file '/Users/xyz/Code/Bitcoin/test-depends/bitcoin/depends/x86_64-apple-darwin20.3.0/plugins/platforms/libqcocoa.a(qcocoaintegration.o)' to global weak symbol 'QMetaTypeIdQObject<QWindow*, 8>::qt_metatype_id()::metatype_id' from file 'qt/libbitcoinqt.a(libbitcoinqt_a-walletcontroller.o)' means the weak symbol cannot be overridden at runtime. This was likely caused by different translation units being compiled with different visibility settings.

Same issue on macOS Catalina 10.15.7 and SDK 10.15.6

Edit: Not the same issue, the GUI will actually start with a depends build on macOS Catalina 10.15.7 and SDK 10.15.6. But this message is displayed in the terminal:

0Unable to create basic Accelerated OpenGL renderer.
1Unable to create basic Accelerated OpenGL renderer.
2Core Image is now using the software OpenGL renderer. This will be slow.```

@jarolrod What is the first dozen of strings in the debug.log (about graphics system)?

Is this os installation on bare metal or virtualized?

jarolrod commented at 6:28 pm on March 17, 2021: member

Currently on VM. Do you want me to make a partition on my MacBook and try it bare metal?

Currently on VM.

This could be a reason for Unable to create basic Accelerated OpenGL renderer.

jarolrod commented at 5:15 am on March 18, 2021: member

@hebasto was able to build and run on bare metal macOS Catalina 10.15.7 without the openGL error. So the 10.15 SDK could be a potential candidate, so is the 10.14 SDK.

I grabbed my CommandLineTools directory from my 10.15.7 installation moved it over to my 11.2 installation and changed the SDK with sudo xcode-select --switch <new-sdk-path>. On my 10.15.7 machine this directory includes xcrun and when you run xcrun --show-sdk-version prints 10.15. But upon moving to the 11.2 machine and switching the SDK, macOS seems to alter some files in this SDK and xcrun --show-sdk-version prints 11.1. So how could I attempt a build on Big Sur using the Catalina SDK? @fanquake maybe you know how to do this properly?

Edit: NVM I have to copy over the entire Developer/ directory not just Developer/CommandLineTools

Currently, I have no detailed explanation for that, but the following command fixes the issue:
