[gentoo-user] Upgrade of gdb this morning failed to compile

[Meino.Cramer]

Hi,

the daily update I usually do failed while compiling gdb:

Before I post every bit/log of the compilation process...

Here are the last lines. Is there already known, how to fix that?

Looks like gdb is linking againt libreadline but libreadline is linked
against ncurses 5 and you're trying to link gdb against ncurses 6. So rebuild 
libreadline which should cause it to link against version 6 and try again.

Also you may want to disable the tinfo flag for ncurses 6 because it's 
problematic and mostly needed by binary packages and I don't think you have 
any linked against ncurses 6.
