Hi,

=app-emulation/qemu-2.8.0 with USE=ncurses does not build. The following error is observed during src_configure():

While ncurses is installed on the system:

[ebuild   R    ] sys-libs/ncurses-6.0-r1:0/6::gentoo  USE="cxx -ada -debug -doc -gpm -minimal (-profile) -static-libs {-test} -threads -tinfo -trace -unicode" ABI_X86="32 (64) (-x32)" 0 KiB

Have this issue as well.  Same experience as described by Bertrand.  I have ncurses-6.0-r1:0/6 installed:

[ebuild   R    ] sys-libs/ncurses-6.0-r1:0/6::gentoo  USE="cxx minimal -ada -debug -doc -gpm (-profile) -static-libs {-test} -threads -tinfo -trace -unicode" 0 KiB

The only thing unusual that I saw at a glance is that minimal USE flag.  I tried rebuilding with USE=-minimal and upgrading qemu again, but it still fails with the same error.

[Comment 3 Matthias Maier 2017-02-13 07:22:11 UTC]

I turns out that qemu needs unicode support in ncurses, i.e. sys-libs/ncurses[unicode].
