Did you try some solutions from google?

I tried, but I didn't use it.
thanks

I also met it, and finally found that moc can't create directory by self, you need mkdir -p GeneratedFiles/Debug in Telegram directory.

to @auchri : I think add mkdir -p GeneratedFiles/Debug to Preprocess is a better choice.
btw, why use Debug directory for qt generated files? I think use qt directory is better, Debug make me confuse with BUILD CONFIGURATION.

1. You don't need to build MetaEmoji project, results are already in the source code here.
2. It is legacy directory path used by Qt, because the moc files in theory can be different for different build configurations (because they respect preprocessor definitions), so originally Qt makes different moc files for different build configurations. But I used only the first one, Debug, for them for all configurations.
