[Bruce Dubbs]

New minor version.

[ken@…]

FTBFS:

/usr/bin/ld: src/bison-complain.o: in function `warnings_print_categories':
/tmp/bison-3.7/src/complain.c:457: undefined reference to `ostream_printf'

(etc)

Already reported upstream by gentoo in thread which starts at ​https://lists.gnu.org/archive/html/bug-bison/2020-07/msg00033.html

Upstream is being too clever. There is one place that uses ostream_printf and another that uses styled_ostream_set_hyperlink, These are just used to format error messages in complain.c.

I was able to get bison to build by adding the following:

static inline ptrdiff_t
ostream_printf (ostream_t stream, const char *format, ...)
{
  va_list args;
  char *temp_string;
  ptrdiff_t ret;

  va_start (args, format);
  ret = vasprintf (&temp_string, format, args);
  va_end (args);
  if (ret >= 0)
    {
      if (ret > 0)
        ostream_write_str (stream, temp_string);
      free (temp_string);
    }
  return ret;
}

to complain.c. I also needed to comment out styled_ostream_set_hyperlink in two places. I took the ostream_printf function from lib/textstyle.in.h.

I'd rather add a patch to bison rather than a new library.

Seems to build OK with gettext-0.21. Patch not needed. All tests pass.
