IIRC the keypad symbol comes from sys-libs/ncurses. Please post the output of emerge -Opqv ncurses to this bug.
I think it's another instance of https://bugs.gentoo.org/729988#c5 where your system somehow has 'libtermcap.so' installed. Can you find where libtermcap.so comes from on your system? For example 'sys-libs/libtermcap-compat' should install only versioned 'libtermcap.so.<number>'
Sergei, your sight was right, thank you. My box had /usr/lib64/libtermcap.so, that might be added by hand to compile some local software (but I don't remember what's that now...). $ locate libtermcap.so /usr/lib64/libtermcap.so /usr/lib64/libtermcap.so.2 /usr/lib64/libtermcap.so.2.0.8 $ equery b libtermcap.so * Searching for libtermcap.so ... $ emerge =sys-devel/gdb-10.1 works after removing /usr/lib64/libtremcap.so.
Yeah, adding symlinks manually would do it. Let's close it as INVALID. Ideally software should be tweaked to use ncurses instead of termcap.
