Qt build failed without any error output, how to get verbose output?

[yanni]

I am building QT 5.15, this is really a long way to go.

The build would stop, without any error output, only warnings. I assume this is related to parallel processing in ninjia, although I use simple make instead of make -j4. Without error, I do not even know where the problem is. I tried make V=1, it did not give any additional information. Is there anyway I can get verbose output? Below is the log where build stopped.

@yanni You can forward the stdout/stderr output into a file and search there for "error". You can also call make again - it will not rebuild what was already built, so it should be easier to spot the actual error.
