Hi, ncurses ebuild has an option to disable share libraries in cross compiler environment. Somehow, it does not work for me. Here is the outpu: bash# i686-pc-mingw32-emerge -1 ncurses Calculating dependencies... done! >>> Verifying ebuild manifests >>> Emerging (1 of 1) sys-libs/ncurses-5.9-r3::gentoo for /usr/i686-pc-mingw32/ * ncurses-5.9.tar.gz SHA256 SHA512 WHIRLPOOL size ;-) ...

The condition to which you refer is only for building some temporary binaries in case ncurses is not up to date on the build system. That's a separate issue. Perhaps do_configure should not forcably enable shared libs for normal building.
Windows should be able to produce shared libs (dll) for ncurses ...
