Error undefined hidden symbol `__dso_handle' can not be used when making a shared object

Question

Yocto 3.4 failed at the glibc 2.34 compilation.

I think that the error happening at the linking stage:

Regarding "__dso_handle", it related to making shared objects.

I don't understand what is the cause of the error. Any idea can help?

The piece of code for that error:

  {
  static int added_atexit_handler;
  char *mallfile;

  /* Don't panic if we're called more than once.  */
  if (mallstream != NULL)
    return;

  mallfile = secure_getenv (mallenv);
  if (mallfile != NULL)
    {
      char *mtb = malloc (TRACE_BUFFER_SIZE);
      if (mtb == NULL)
        return;

      mallstream = fopen (mallfile != NULL ? mallfile : "/dev/null", "wce");
      if (mallstream != NULL)
        {
          /* Be sure it doesn't malloc its buffer!  */
          malloc_trace_buffer = mtb;
          setvbuf (mallstream, malloc_trace_buffer, _IOFBF, TRACE_BUFFER_SIZE);
          fprintf (mallstream, "= Start\n");
          if (!added_atexit_handler)
            {
              added_atexit_handler = 1;
              __cxa_atexit ((void (*)(void *))release_libc_mem, NULL,
                __dso_handle);
            }
      __malloc_debug_enable (MALLOC_MTRACE_HOOK);
        }
      else
        free (mtb);
    }
}

Answer 1

I tried with the definition in dso_handle.h as below:

void *__dso_handle __attribute__((weak)) = NULL;

But, it didn't work in my case.

The error looked like comming from gcc compatibility.

And my solution is

I upgraded the build host's gcc version (>= 7.5.0) then cleanup and rebuild glibc. And the result is okay.
