ncurses 5.7 doesn't build libtermcap anymore?

ncurses 5.7 doesn't build libtermcap anymore?

[Mike Westerhof]

I've been working on some recent problems that popped up in the SlugOS
feeds; one that appeared recently is that asterisk no longer builds;
configure complains about -ltermcap, and investigation shows that
indeed, libtermcap is missing.  It seems that the new ncurses recipe
(5.7) no longer builds it for some reason.  I think the same problem is
the root cause for the failure of js to build as well.

So I guess the first question is if this is intentional or not?  If it
is, then I guess I'll modify the asterisk recipe to remove the
dependency and submit that patch.  Otherwise, well, I guess I could
attempt to debug and fix the ncurses recipe, but it looks a bit, um,
"non-trivial" so any advice would be appreciated.

Or should I just pin ncurses to the old 5.4 version that worked?

Thanks,
-Mike

AFAICT libtermcap is now in libncurses. so either we can create a
symlink called libtermcap.so pointing
to libncurses.so or we can fix the recipes to link with -lncurses
instead. I think first approach might be
better.

Hi Mike,

it's because 5.7's configure is using --with-ticlib which is 
incompatible with --enable-termcap.
On ubuntu, it seems they simply do the following links :
usr/lib/libncurses.so usr/lib/libtermcap.so
usr/lib/libncurses.a  usr/lib/libtermcap.a

5.7 is also broken for sdk build, I'm currently trying to fix this, I've 
add the link and tested asterisk's build, patch is coming.

When I remembed an irc discussion, asterisk (tested on version 1.6.0.28)
is able to use -ltinfo from recent ncurses.  afair, the explicit

  --with-termcap=${STAGING_EXECPREFIXDIR}

must be removed from the recipe too.

libtermcap is dead and unmaintained since 1996 (!).  Recent software
should be able to use -ltinfo instead of -ltermcap.

Recent js-1.8.0rc1 brings in the -ltermcap by

| ifdef JS_READLINE
| ...
| PROG_LIBS += -lreadline -ltermcap

libreadline itself should be linked against the correct termcap library
(ltinfo or ltermcap) so that this '-ltermcap' can be removed.

Accordingly Makefile.ref, the '-DUSE_TERMCAP' option requires manual
addition of '-ltermcap' to LDFLAGS (which is btw usually the wrong
variable for extra libraries).

So, when somebody revives the js recipe (last package specific changes
were in Feb 2007) and sets '-DUSE_TERMCAP', (s)he should link against
'-ltinfo'.

We could provide like Fedora a linkerscript 'libtermcap.so' with

| INPUT(-ltinfo)

content.  But I am not sure whether -ltinfo is really 100% compatible
to -ltermcap and if such a workaround would break autodetection which
checks whether termcap or tinfo is to be used.

This part is wrong; libtermcap functionality is provided by libtinfo and
does not need whole libncurses.

A linker script libtermcap.so with

| INPUT(-ltinfo)

might be a better solution for .so.


> +	ln -sf libncurses.so.5 libtermcap.so.5

This is not needed; DL_NEEDED will be libtinfo.so.X both if you create a
symlink or use the linkerscript.  There is nothing with a libtermcap.so.5
SONAME either.

that's the way it's done on ubuntu so I thought this could be ok -but it 
seems there is no libtinfo on ubuntu which may explain this point), I 
will switch the link to libtinfo and test asterisk build.

I do not see a reason, not to apply '--with-ticlib' to widec.  I changed
this in git.

I think that I fixed widec builds for native targets in git. 'sdk' and

well if the meaning of noticing is spending 2 days on this recipe trying

Thanks for finishing the work, I'm currently rebuilding from scratch to 
test.
