What are the dependencies for qt5? I am just starting an ebuild, see https://github.com/gentoo/gentoo/compare/master...charIes17:dhcpcd-ui.
Any help for completing the ebuild is much appreciated.

Thanks for your help. Just added qtgui, qtcore and qtwidgets, see https://github.com/gentoo/gentoo/compare/master...charIes17:dhcpcd-ui#diff-9dfb4ad0513d7a4d04a7eb30eef96320R40 But dhcpcd-qt is not being built:

You need also add sys-libs/ncurses[tinfo] as dependency (for curses ui).
I have another erro when compiling package:
Code:

/lib64/libtinfo.so.6: error adding symbols: DSO missing from command line

This because in configure LIB_CURSES variable -ltinfo is missing.

        fi

EDIT: Not sure if tinfo use flag in ncurses is required but in my system with it enabled I have the error

Yep, forgot to set qt5. Thanks for your attention.

Still need to care for the icons:

Remember to check if tinfo is enable in ncurses (and also add it as dependency) and add -ltinfo to LDFLAGS. I think that this must be checked in configure.

Shouldn't that patch go upstream? Or is it just only for Gentoo?

Yes but this patch is only a workaround that only work on a system with ncurses[tinfo] but fails in other case.
The correct way is that configure check if tinfo is present and only in this case add -ltinfo, but I've not idea how to do.

Why should I even know about tinfo? dhcpcd-curses only makes curses calls.
On NetBSD, curses and terminfo are separate libraries and it works fine. Maybe fix ncurses?

Probably you right and problem is related to this tracker.
A good patch for gentoo can be

Does it really only affect the live ebuild or also dhcpcd-ui-0.7.5-r1?

Only live because version 0.7.5-r1 didn't ncurses ui. You can also resolve problem adding src_prepare function in ebuild
