Re: Gawk 3.2.1 on HP-UX

[Michael Elizabeth Chastain]

I've run into this problem.

The issue is that HP-UX 11i has partial support for multibyte libraries.
The gawk configury machinery sees the partial support and turns on
multibyte support, but then the build fails because of the lack of full
support.

---

One solution is to patch the multibyte configuration machinery.  At the
end of this message is a patch for gawk 3.1.3.  I tested this with
several compilers and multibyte environment settings, and have been
using it regularly on hppa2.0w-hp-hpux11.11.

After applying this patch, you have to touch (or regenerate) these
files:

  sleep 2 ; touch gawk-3.1.3/aclocal.m4
  sleep 2 ; touch gawk-3.1.3/configh.in
  sleep 2 ; touch gawk-3.1.3/configure
  sleep 2 ; touch gawk-3.1.3/patchlev.h
  sleep 2 ; touch gawk-3.1.3/version.c

---

Here's an alternative that should probably work and is definitely
simpler.  I haven't tested this, though.  Before you configure gawk, do
this:

  export ac_cv_func_mbrlen=no
  export ac_cv_func_mbrtowc=no

If you use csh or tcsh, the command would be:

  setenv ac_cv_func_mbrlen no
  setenv ac_cv_func_mbrtowc no

This pre-answers some of the configuration probes to disable
some of the multibyte functions.  No source change needed.

Would you mind trying this out and sending an email back to the
list about whether it works or not?

---

All this should be sorted in the next release of gawk.  I've been
testing pre-releases on hpux 11.11 with gcc and hp ansi c and
it's working in the pre-releases.

Hope this helps,

Michael C
