Hi!

This is is what I see:
CFDISK is a separate flag that sets FDISKS.
FDISKS is then used to build all fdisks.
But only the selected fdisks get installed.
I don't see an error here?

but unfortunately if also no other packages that use the ncurses library
are also not selected, when cfdisk is compiled the following error occurs:

Do I understand it correctly when you say that the only user of ncurses
in your entire build is cfdisk? Seems quite odd, hence my rather stupid
question. In that case, can you please check that NCURSES actually gets
built before util-linux?
And that your selected ptxconfig contains ncurses?

I couldn't reproduce this in 09 or 10. x86_64 or arm-v7a.
Now I don't have an ncurses cfdisk only build nor do I have OSELAS as
toolchain. I don't think the latter should make much of a difference
though. Our toolchain for arm-v7a looks rather similar in components.

Thanks for the answer Christian, I'm at home now, but I remember that there were actually three sub-packages of util-linux that were selecting ncurses, in my configuration, by chance, none of them was selected and no other packages in the whole configuration are using ncurses, as my device is fully headless, there is no need for it.
The problem is that cfdisk can be individually de-selected in menuconfig, but still it is build, if is actually installed in the fw image even if deselected, this I don't know, I can test if you like.
Would be nice if cfdisk (and other parts of util-linux that can be individually deselected in the configuration menu) could be inhibited to be build at all when not selected, I don't know if is possible as an util-linux configuration parameter.
Right now, if I select cfdisk in the configuration menu, the build succeeds but I have yet another library that I don't need as well as anotother useless utility (for the specific use case).
I really don't know how to solve this, and I will be happy to learn from this, the whole Meson crazyness is still new to me.
BTW, the previous release set of rules are working, but I believe these are still autoconf based.


 Best regards,
 Mircea
