kde-apps/umbrello-18.08.3 build failure: what is wrong?

[hujuice]

The full (pretty big) build log is at https://gist.github.com/hujuice/67058f8 ... 55b064e56c
(You can also find there a grep -n filter for error and warning, to move in the 2517 lines.)

The failure(s) depend on namespaces or undeclared variables, but I don't understand how to investigate.

The first error is at line 2375 (and following). The line is huge and the error itself is too much to be reported here. Here's the initial part:

Code: Select all

The first warning, before and with a similar "flavour", is at 1743. Again, the line is huge and the message is :

Is anyone able to understand what's happening?

Thanks to everybody,

Resolved by attempt building again kde-frameworks/kcoreaddons, dev-qt/qtcore and dev-qt/qtgui
Not the best way to understand a problem. No idea about the reasons.

This was fixed in umbrello itself. https://bugs.gentoo.org/677868

Well, I didn't check the bugzilla anymore, and I should.

Thanks,
