Created attachment 431848 [details, diff] Add std:: prefix This patch adds the std:: prefix two to occurrences of isnan. Those are the ones for Qt; the ones for Gtk are left alone since they will get compiled as C code.
Also fixed upstream here: https://quickgit.kde.org/?p=qtcurve.git&a=commit&h=34a1e3277aa21c59029576bffe2576a9ddd4b1a7
(In reply to Martin von Gagern from comment #1) > Created attachment 431848 [details, diff] [details, diff] > Add std:: prefix This patch works for me.
I cannot reproduce this issue. x11-themes/qtcurve-1.8.18-r1 emerges fine with sys-libs/glibc-2.23-r2 installed.
Patch applied integrated into x11-themes/qtcurve-1.8.18-r1.
