Hello,

• krb5-1.16.3/src/configure.in searches for libncurses and if it cannot find it, gives up. It should also search for
libncursesw (in particular, when libreadlinfo is linked towards libtinfow.so).

• rename configure.in → configure.ac

Regards
Дилян

What platform does this problem apply to?

Ideally I'd like to use pkg-config here, but I don't think readline
provides a pkg-config file.

Alternatively, we could eliminate the -lncurses (and possibly -lhistory
since I think we don't use it directly) and just assume that the
platform has functional library dependencies and a shared libreadline.

Hello,

it is a “Linux from Scratch”.

sorry to jump in, but I think linux from scratch has libncurses.so pointing to
libncursesw.so. Exactly, they do:
for lib in ncurses form panel menu ; do
rm -vf /usr/lib/lib${lib}.so
echo "INPUT(-l${lib}w)" > /usr/lib/lib${lib}.so
ln -sfv ${lib}w.pc /usr/lib/pkgconfig/${lib}.pc
done
So libncurses.so is a linker script, and passing -lncurses is equivalent to
passing -lncursesw.

Now, whether krb5 configure should use a different method is another story.

Hello,

I think this statement for LFS was in the past (15 years ago) not valid.

Anyway, it does not matter which kind of system it is. If libncursesw is available and libncurses is missing,
./configure shall be happy.

Simplify libreadline configure support

If configure is explicitly asked to build with libreadline, look for
and link against only -lreadline, relying on the platform to resolve
any dependencies.
