[Buildroot] [PATCH] pakage/erlang: fix host build without termcap (curses) library

[Yann E. MORIN]

We do not need termcap (curses) support in the host variant of erlang.

Fixes a bunch of autobuild failures;

Cc-ing Nathaniel, as all failures happen on his build server. Thomas and
Nathaniel, could you please review the setting of that autobuild server?
And the others as well?

It seems legit ncurses is missing on a build server, but we did not notice,
because we do require it for menuconfig and nconfig, so virtually everyone
has it, and it is most probably installed on other autobuild servers
because owners want to be able to run menuconfig on them to debug stuff.

Care to have a look, please?

Regards,
Yann E. MORIN.

I haven't installed libncurses-dev per the discussion we had a few
weeks/months back. (Basically only use the system's ncurses for 'make
*config', and in all other cases build it)

I haven't heard otherwise, and this is also causing failures in
host-mysql (IIRC).

If you both believe that I should install it, I will, but I still
believe it is better to build host-ncurses.

Thanks, Nathaniel.

We already discussed this on the mailing list some time ago.
Nathaniel's build server is the only one where libncurses-dev is not
installed in the system. And since libncurses-dev is not part of our
mandatory dependencies (someone could very well use gconfig or xconfig
only, for example), we thought that keeping Nathaniel's configuration
as is was a good way of catching the cases where we have a missing
dependency on host-ncurses.

I remember we even had a discussion to decide whether we should build
host-ncurses in such cases, or whether we should make libncurses-dev a
hard dependency of Buildroot, and Peter decided that building
host-ncurses was the right solution.

Best regards,

Thomas

Ah, OK. I've overlooked that discussion, then. Thanks!

Yes, I fully agree with this. No need to fix your autobuild instance.

Thank you!

I fully back this resolution. It is very often that a build server
(whether it is for us to do autobuilds, or a production build server)
lacks such libraries.

So, we have to fix such build failures by either:
  - adding a dependency on host-ncurses, or
  - disabling ncurses/termcap support for the host tools if it makes
    sense and it is possible, otherwise revert to depending on
    host-ncurses.

Thank you!

Regards,
Yann E. MORIN.
