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:

yields:

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.

your libkipi is outdated. You need current git/master code from libkipi to compile current digiKam until final digiKam release. libikipi API is not yet fully stabilized, and library is not yet released officially.

Thanks, solved it.

I was building from the latest tag in libkipi thinking it was a good idea, since I wasn't able to build master.

I had to disable building of tests to finally get libkipi/master to build, though.

Thank you very much.
