Build errors

[kynn]

I want to be able to do

  autoload colors zsh/terminfo

in a script, but my ISP does not support the zsh terminfo module, so I
tried compiling zsh from source.  After running ./configure I modified
the link parameter terminfo line in config.modules from

name=zsh/terminfo modfile=Src/Modules/terminfo.mdd link=static auto=yes load=yes

to

name=zsh/terminfo modfile=Src/Modules/terminfo.mdd link=dynamic auto=yes load=yes

My goal was to put the compiled terminfo.so file in my $HOME/.zmodules
directory, and add this directory to my modules_path variable.  (Then
I would discard the rest of my compiled zsh, and use the zsh provided
by my ISP in /usr/local/bin.)

When I ran make, it tripped on terminfo:

  gcc -c -I.  -DHAVE_CONFIG_H -DMODULE -Wall -Wmissing-prototypes -O2 -fPIC -o terminfo..o terminfo.c
  In file included from terminfo.c:53:
  /usr/include/curses.h:452: `underscore' redeclared as different kind of symbol
  ../../Src/init.epro:6: previous declaration of `underscore'

  terminfo.c: In function `boot_':
  terminfo.c:385: warning: implicit declaration of function `setupterm'
  *** Error code 1

  Stop.

There seems to be some conflict with the local system's curses.h file.
Is there any way I can fix this?

Here are some system details:

  % uname -ar
  NetBSD my_isp3.my_isp.com 1.5.4_ALPHA NetBSD 1.5.4_ALPHA (MY_ISP-USER) #0: Thu Feb 26 14:11:15 EST 2004     root@some_host.my_isp.com:/devel/NO-BACKUPS/release-1.5-20020917/src/sys/arch/i386/compile/MY_ISP-USER i386

Thanks!

You may actually need ncurses for the terminfo module to work.

But zsh configure may not be accurate enough in its searching of
supported libraries. It shouldn't have selected "curses" here as
it has no support for "tigetstr..."

I suspect the library, as opposed to the header, actually does.  The
rule in terminfo.mdd is that the file is only compiled if
tigetflag is found; it doesn't bother checking for all the
tiget... functions since either all or none should be available.  This
suggests it's only the header that's defective, or at least not what the
configuration is assuming.  This changed in 4.2; before that the tests
were a bit more hit and miss.
