[Nix-dev] ncurses failing with glibc

[Malcolm Matalka]

Hello, last night I did:

nixos-rebuild switch
nix-env -u '*'

And now I have the following error when trying to link ncurses programs:

/run/current-system/sw/lib/libncursesw.so: undefined reference to
`memcpy at GLIBC_2.14'

I've tried uninstalling and reinstalling ncurses with no effect.  I
noticed there is another thread related to this but reinstalling Opera
seemed to have fixed that persons issue.  What is the suggested
solution?

Thanks,
/Malcolm
