[Pan-users] configure error with iconv - no ISO-2022 support?

[Himanshu J. Gohel]

I was browsing both the archives for comps.sys.sgi.* and the Pan-users
mailing list to find a solution to this problem, but I didn't find any
that solved the problem, just questions (see Msg-Id:
<address@hidden>).

If I run configure on Pan 0.14.0 sources, I get an error:

checking preferred charset formats for system iconv... not found
configure: error:
        *** The iconv-detect program was unable to determine the
        *** preferred charset formats recognized by your system
        *** iconv library. It is suggested that you install a
        *** working iconv library such as the one found at
        *** ftp://ftp.gnu.org/pub/gnu/libiconv

One suggested solution was to specify the path to iconv, which I
did, but I still go the same errors.  Turns out that specifying the
path is done like so: --with-libiconv-prefix=/usr/freeware which then
looks
in /usr/freeware/lib and /usr/freeware/include.  But libiconv.a was in
lib32, so I made a link from lib/libiconv.a lib32.  Still did not solve
the
problem.

So I looked in the config.log as DRK suggested in his response.  Turns
out that iconv passes the first two tests:

configure:6943: checking for iconv
configure:7058: checking for iconv declaration

But fails this third test:

configure:7127: checking preferred charset formats for system iconv
 <snip>
configure:7155: $? = 0
configure:7157: ./conftest
System prefers ISO8859-1
System doesn't support any ISO-2022 formats
configure:7160: $? = 3
configure: program exited with status 3
configure: failed program was:

Looking at the code left behind in iconv-detect.c, the code says:

        iso2022 = ISO_UNSUPPORTED;
        info = iso2022_tests;
        /*printf ("#define ISO_2022_FORMAT(iso,codepage)\t");*/
        for (i = 0; i < num_iso2022_tests; i++) {
                cd = iconv_open (info[i].charset, "UTF-8");
                if (cd != (iconv_t) -1) {
                        iconv_close (cd);
                        /*printf ("(\"%s\", (iso), (codepage))\n",
info[i].format);*/
                        fprintf (stderr, "System prefers %s\n",
info[i].charset);
                        iso2022 = info[i].id;
                        break;
                }
        }

        if (iso2022 == ISO_UNSUPPORTED) {
                fprintf (stderr, "System doesn't support any ISO-2022
formats\n");
                fprintf (fp, "#define ICONV_ISO_S_FORMAT \"%s\"\n",
info[0].format);
#ifdef CONFIGURE_IN
                exit (3);
#endif
        } else {
                fprintf (fp, "#define ICONV_ISO_S_FORMAT \"%s\"\n",
info[i].format);
        }


And that's where it's getting the return code of 3, and failing.
Question is, how can I get the test to pass?

Thanks for any ideas.
