According to the ncurses 6.0 release notes (the site is at
"https://www.gnu.org/software/ncurses/"), the intent of the release is
to provide a new stable ABI,
which is binary-incompatible with ncurses 5, but it can still be
configured to support the ncurses5. Because this release introduces
symbol-versioning.
The symbol-versioning allows the developers of a library to mark each
public sysmbol(both data and functions) with an identifier denoting the
library name and
the version for which it was built. By doing this , users of the library
have a way to help ensure that applications do not accidentally load an
imcompatible library.
In addition, private sysmbols can be hidden entirely.

When I first release the patch 5.9 -> 6.0 with the option
--with-abi-version=5, I want to be compatible with the existing system,
so I do the following test:
$bitbake world core-image-sato-sdk
tested it on the qemuarm, qemux86, qemux86-64 with multilib (oe-core),
and no error happened .

When I second release the patch "drop the compatible option
--with-abi-version=5", because I want to introduces the feature
symbol-versioning, so I droped the
option --with-abi-version=5 , and I do the following test:
$bitbake world core-image-sato-sdk
tested it on the qemuarm, qemux86, qemux86-64 with multilib (oe-core),
and no error happened.
Today, Robert let me test it on the following layers:
/meta-openembedded/meta-oe
/meta-openembedded/meta-networking
/meta-openembedded/meta-meta-webserver
so I add the layers to my build and run the following commands:
$bitbake world
It reported the following error:

It seems the umip was affect by the ncurses version change. So I went to
the log.do_compile, the log file say:
fatal error: gram.h : No such file or directory
compilation terminated
So I think the ncurses version change didn't affect the whole system.
Then I release the patch "ncurses: drop the compatible option"
