Hm, haven't looked in depth yet, but only happens with the new =ncurses-6.2_p20210619 snapshot.

[Comment 8 Sven Hesse 2021-07-26 12:45:54 UTC]

setcchar() seems to be a wide character function, so it's only available when ncurses was built --enable-widec, as the ncurses ebuild does for the ncurses*w targets.

Which means that linking the programs with -lncursesw instead of -lncurses works.

I'm attaching a patch which changes ncurses to ncursesw in the configure script. It's not really the clean way to do this (it should probably probe for ncursesw vs ncurses), but it works.

Patch that fixes compilation with ncurses-6.2_p20210619

[Comment 10 Ionen Wolkens 2021-07-26 12:57:21 UTC]

I did notice that it works with ncursesw already, but why did it work before and now doesn't?

There was no changes in the ncurses ebuild regarding regarding --enable-widec I can see.
