Certainly possible. That's not the tactic we took on resolving the issue. One
line change vs significantly modifying the package. The following is the chunk
that handles the dynamic generation (from ncurses.inc)
python populate_packages_prepend () {
libdir = d.expand("${libdir}")
base_libdir = d.expand("${base_libdir}")
pnbase = d.expand("${PN}-lib%s")
do_split_packages(d, libdir, '^lib(.*)\.so\..*', pnbase, 'ncurses %s
library', prepend=True, extra_depends = '', allow_links=True)
if libdir is not base_libdir:
do_split_packages(d, base_libdir, '^lib(.*)\.so\..*', pnbase, 'ncurses
%s library', prepend=True, extra_depends = '', allow_links=True)
}
Beyond this even, the package has a number of dynamic configurations that should
probably be done based on libc and/or distro flags as well.
So this is probably a job for a janitor task.
I still think as a minimal change the PACKAGES_DYNAMIC is the correct change,
but as you said -- during a cleanup -- the need for PACKAGES_DYNAMIC can be
diminished or removed.
