I'm pretty sure this is an issue with Qt and newer versions of make. What version are you using here?

Qt is 5.9.8 as it is built in depends.

$ dpkg --status make | grep Version
Version: 4.1-9.1ubuntu1

It seems nothing unusual...

fanquake commented at 12:02 PM on April 7, 2020: member

If you try and build with an older version of make, like 3.8x, I'm pretty certain it will work. I have seen this same failure before.

Built and installed the old make:

$ make --version

but it didn't help:

$ make qt -C depends
...
Project ERROR: Unknown module(s) in QT: xml

make: Leaving directory `/home/hebasto/bitcoin/depends'

And the log does not mention funcs.mk:251: ... now.

fanquake commented at 11:36 PM on April 8, 2020: member

Right, so I guess it's only on macOS where using an older make fixes the issue. In any case, this seems like something that should be taken upstream to Qts bug tracker. I don't think we need an issue open for it here.

I've managed to build Qt in depends on Armbian Focal (on the same ODROID-HC1) with the following diff:

Also the build system didn't find zconf.h header in the depends/armv7l-unknown-linux-gnueabihf/include directory. So the following was required:

$ sudo apt install zlib1g-dev

Eventually,

$ make qt -C depends

Is this fixed after #21376 ?

Should be fixed in Qt 5.15.x (https://github.com/bitcoin/bitcoin/pull/21589#issuecomment-833381710).
