[Message part 1 (text/plain, inline)]

The command I used was (I'm doing an out of tree build)

../../src/emacs-24.0.90/configure --with-jpeg=no --with-png=no --with-gif=no --with-tiff=no

The last few lines printed are:

  ...
> checking for getpt... no
> checking for library containing tputs... no
> configure: error: I couldn't find termcap functions (tputs and friends).
> Maybe some development libraries/packages are missing?  Try installing
> libncurses-dev(el), libterminfo-dev(el) or similar.


The config.log file is attached:



I'm happy to help out anyway I can.

Thank you,
pedz

The error message says:

  I couldn't find termcap functions (tputs and friends). Maybe some
  development libraries/packages are missing? Try installing
  libncurses-dev(el), libterminfo-dev(el) or similar.

(I think the wording could be improved a bit.)

configure checks for the tputs function in any of libncurses,
libterminfo, and libtermcap. Your system does not seem to have any of
them:

collect2: library libncurses not found
collect2: library libterminfo not found
collect2: library libtermcap not found

Please try either installing one of these libraries and its header
files, or if they are already installed explicitly telling configure
where they are; eg:

CFLAGS=-I/path/to/terminfo/include LDFLAGS=-L/path/to/terminfo/lib ./configure

I think the configure test is incorrect.
For example on Solaris this would find libtermcap, where previous emacs
version would use libcurses, which would be the better option.

The current test is due to

PS I've always thought there was something weird here with the way
HAVE_LIBNCURSES can be defined even if you don't have libncurses.
(Maybe the define is just badly named.)

PPS are you sure this is an issue, because later on we see:

case "$opsys" in
  aix4-2|cygwin|hpux*|irix6-5|openbsd|sol2*|unixware) TERMINFO=yes ;;
  [...]
esac

[...]

if test $TERMINFO = yes; then
   [...]
   test "x$LIBS_TERMCAP" = "x" && LIBS_TERMCAP="-lcurses"
   [...]
fi

As a test, I built 24.0.90 on Solaris and indeed it linked to libcurses
and not libtermcap.

In fact on the machine where I tested, it turns out that libtermcap.so
is just a symlink to libcurses.so.

Is that the same on AIX? 
Where is tputs on that platform? 
If it's in libcurses, then the autoconf test would fail...

So perhaps libcurses should be added to the list of places that is
searched for tputs.

Whee, on RHEL6 libcurses.so is just a text file containing INPUT(-lncurses).

Perry, please can you try changing line 14364 of 24.0.90's configure
script so that it reads:

  for ac_lib in '' ncurses terminfo termcap curses; do

and see if that helps? (I assume you are using a pretest tarfile with a
prebuilt configure rather than generating it from configure.in with
autoconf. If the latter, change line 2774 of configure.in.)

That worked.

AIX has its tputs in libcurses.  AIX also has a libtermcap that is suppose to be compatible but most systems don't install it and I would try avoid using it.  You might consider moving curses in front of termcap.

Thanks for the help.  I'll try and do the make and see where that lands me.

Thanks, installed.

For now, I left curses at the end of the list, since that is the most
conservative change.
