[Digikam-devel] Compiling DigiKam: conflicting return type specified for virtual void Digikam::KipiInterface::preview(const QUrl&, int)

[Tobia Tesan]

Hello, I'm having a particularly hard time compiling DigiKam.

I'm trying to build 71bed47 on a clean Fedora 23 machine, and I hit this 
error:

I am rather clueless.

On a fresh clone the command sequence:

> [tobia at Host-001 digikam]$ git show -s

> [tobia at Host-001 digikam]$ git diff
> [tobia at Host-001 digikam]$ cmake . > cmake.log 2> cmake.err && make > make.log 2> make.err

yields:

make.log: http://pastebin.com/5B9EtuGh
make.err: http://pastebin.com/wL55bU3W
cmake.log: http://pastebin.com/WiSVcgQM
cmake.err: http://pastebin.com/YjkF4Aty

(Sorry for not attaching them directly, their length triggers a ML filter)

I have tried the latest tag, with the same results.

I also tried the digikam collection repository, but had a number of 
other, different issues with building dependencies.

Is there a surefire, tested configuration to build digikam on?
A preferred distro I can install on a fresh VM?

Thank you very much.
