no, 'DEPENDS = "ncurses-native"'; BUT:

Isn't the whole point of ASSUME_PROVIDED that user be aware?
Would be too arbitrary in this case because it forces people to check by
trial & error whether ASSUME_PROVIDED are working. A raw guideline for
adding an entry to ASSUME_PROVIDED should be, whether a corresponding,
recent -devel package has been installed on the host.
That seems totally backwards. The guideline for adding an entry to
ASSUME_PROVIDED is that you know better than the build system. No one
doing commits for native packages should have anything set, or at least
confirming that having an empty set (aside from bitbake.conf anyhow...)
works fine too as that's the common case.
imo, packages should not have so strict requirements on the actual
provider but check in their configure task what to use (this includes
autodetection of libtinfo vs. libtermcap vs. libncurses).
Yes, and we're grappling with the fallout of a big switch, which
includes fixing up (or upgrading) other packages to be happy with a
given version.
For cmake, problem above can by solved by an initial configuration
script having
| SET (BUILD_CursesDialog OFF CACHE BOOL "" FORCE)
Great, lets do that.
* some hours ago I added a libtermcap.so compatibility symlink to
ncurses(-native) so that 5ea3047995421d99f7f3537cb8f9ae23f3185a9f
might not be needed anymore
Um, is there a reason this wasn't just done as a ln within the recipe?
It's a mix of personal preference, following Fedora's packaging of this
file and the hope to use some more of the power of linker scripts (giving
out a deprecated warning, add AS_NEEDED, linking against multiple files).
There was no opposition when I wrote about linker scripts neither.
Perhaps I should have made it inline by 'echo INPUT(-ltinfo) > ...' but
I did not saw this when I committed the patch.
Well, it wasn't at all clear from the commit message why anything more
than a symlink was done. So can you please add a comment and a commit
message explaining what's going on here? Thanks!
