On Gentoo, the base-system maintainers refuse to do this (I would agree if you call it a bug on our side), but I am not allowed to touch those packages. Luckily ncurses provides the config scripts and the pkg-config modules to do sane linking. This should be done if possible regardless the situation on a single distributions. > > If I just configure ncurses with: > $ ./configure --with-termlib --with-shared --without-normal && make > $ readelf -d lib/libncurses.so.5.9 |grep tinfo > 0x0000000000000001 (NEEDED) Shared library: [libtinfo.so.5] > > I wonder how you configured your ncurses. ./configure --prefix=/usr --build=x86_64-pc-linux-gnu --host=x86_64-pc-linux-gnu --mandir=/usr/share/man --infodir=/usr/share/info --datadir=/usr/share --sysconfdir=/etc --localstatedir=/var/lib --libdir=/usr/lib64 --with-terminfo-dirs=/etc/terminfo:/usr/share/terminfo --with-shared --without-hashed-db --without-ada --with-cxx --with-cxx-binding --without-debug --without-profile --with-gpm --disable-termcap --enable-symlinks --with-rcs-ids --with-manpage-format=normal --enable-const --enable-colorfgbg --enable-echo --enable-pc-files --enable-warnings --without-assertions --disable-leaks --without-expanded --with-macros --without-trace --with-termlib --with-chtype=long --with-mmask-t=long --disable-ext-colors --disable-ext-mouse --without-pthread --without-reentrant > > Thanks for staying around during the iterations. No problem, this is how it works. Thanks for your suggestions, Justin
