Configuring nepomuk-core failed

I got the following error building nepomuk-core after upgrading to High Sierra (and following the migration guide)

Configuring now works, but I get the following while building

Please attach the new main.log file so we can see the error.

[riccardobrasca]

I already attached the new file (overriding the old one, sorry if this was not clear).

[mf2k (Frank Schima)]

I see now. Thank you.

I see the failed ld failure as well.

I don't understand, sorry. Is there a workaround (or a solution) to the problem? Thank's!

[NicosPavlov]

Sorry, the comments above were mostly a note to myself, explaining what I gathered from the issue. I am looking into solving it.
