v1.22.0 pkg fails usage test

[claybridges]

On Big Sur 11.2.3.

Steps to reproduce:

1. Follow instructions in README to uninstall existing.

2. Follow instructions in README to install 1.22.0.pkg, basically like this:

git clone https://github.com/pqrs-org/Karabiner-DriverKit-VirtualHIDDevice.git
cd Karabiner-DriverKit-VirtualHIDDevice
open dist/Karabiner-DriverKit-VirtualHIDDevice-1.22.0.pkg
/Applications/.Karabiner-VirtualHIDDevice-Manager.app/Contents/MacOS/Karabiner-VirtualHIDDevice-Manager activate

3. Follow instructions in Usage section to test, basically like this:

cd examples/virtual-hid-device-service-client
make
make run

Expected results: Test works
Actual results:

$ make run
sudo ./build/Release/virtual-hid-device-service-client
Password:
Press control+c to quit.
connect_failed asio.system:2
connect_failed asio.system:2
connect_failed asio.system:2
^Cconnect_failed asio.system:2

Have confirmed tests work with pkg 1.15.0 and checked out at tag v1.15.0.

I cannot reproduce this issue.
Are there any error messages in /var/log/karabiner/virtual_hid_device_service.log?

[claybridges]

Just retried. Here's the log:

virtual_hid_device_service.log

And here's the command line:

$ make run
sudo ./build/Release/virtual-hid-device-service-client
Password:
Press control+c to quit.
connect_failed asio.system:61
connect_failed asio.system:61
connect_failed asio.system:61
connect_failed asio.system:61
connect_failed asio.system:61
connect_failed asio.system:61
^Cconnect_failed asio.system:61

Different asio error this time... ¯\_(ツ)_/¯ .

Test #2/more info:

• load the generated .xcodeproj into Xcode
• add default scheme
• set to run as root
• run

And it works fine. Still fails via make run.

Thank you for your confirmation!
It seems Karabiner-DriverKit-VirtualHIDDevice services works well on your machine.
So I guess this issue is caused by version mismatch of example code.

Although I try to avoid it, incompatible changes are sometimes made in the client libraries.
v1.16.0 changed the file name of the UNIX domain socket used for communication.
Due to this change, previous example code cannot communicate with the v1.22.0 driver.

Please upgrade to your repository and build examples again.

I always run the repo code vs. the correct package (per the commit tag), E.g. commit tag v1.22.0 vs. dist/Karabiner-DriverKit-VirtualHIDDevice-1.22.0.pkg.

This session is present master branch vs. 1.22.0, which should be OK, right?:

Thank you for detailed information!

Hmm, it seems the binary is not rebuilded.
Does executing make clean before make solves this issue?

make clean
make
make run
