How to Troubleshoot "Inconsistency Detected: Dl-Lookup.C: 111" (Java Result 127) Error

debugging ld, Inconsistency detected by ld.so

Inconsistency detected by ld.so: dl-version.c: 224: _dl_check_map_versions: Assertion 'needed != ((void *)0)' failed!

This is a bug in glibc, or a corruption in one of your shared libraries. The glibc code reads:

  while (1)
  {
     ElfW(Vernaux) *aux;
     struct link_map *needed = find_needed (strtab + ent->vn_file, map);

     /* If NEEDED is NULL this means a dependency was not found
        and no stub entry was created.  This should never happen.  */
     assert (needed != NULL);
 ...

Your options at this point are:

• reinstall and verify md5sums for all libraries involved to rule out on-disk corruption, and
• install debuginfo package for glibc, and try to understand which library and which symbol version is triggering the assertion, or
• report this in appropriate bug tracker for your Linux distro.

Setting LD_DEBUG=symbols,bindings or even LD_DEBUG=all may also provide some clues on exactly which symbols are being looked up.

Java: Creating an array of only duplicates

If I'm understanding what you're after correctly, I think you're probably making this a lot harder than it has to be.

It is much easier to iterate over your fields array in order and add two Fields of the same value each iteration, then shuffle the array. Something like the following code:

{
    ...
    for (int i = 0; i < fields.length; i += 2)
        fields[i] = fields[i + 1] = new Field(r.nextInt(pool));

    shuffleFields(fields);

    return fields;
}

You can take your pick of shuffling algorithms. The Fisher-Yates shuffle is popular. E.g.:

void shuffleFields (Field[] fields)
{
    Random r = new Random();
    for (int i = fields.length - 1; i >= 1; --i)
    {
        int j = r.nextInt(i + 1);
        Field t = fields[i];
        fields[i] = fields[j];
        fields[j] = temp;
    }
}

Libgdx desktop does not run - WARNING: An illegal reflective access operation has occurred

What version of libgdx and java are you using?

---

For the error check this question

Like you the questioner used libgdx under ubuntu with a newer version of the open jdk.
Downgrading to version 8 seemed to have resolved that issue.

---

The warnings basically says something along the lines that the underlying code uses functionality that has been deprecated and is pending for removal. Using a newer version of libgdx might solves that issue.

However some of those issues might not be resolved as libgdx does not seem to be under (much) active development anymore. The usual recommondetation is to not use anything beyond JDK 8.

According to the repo (for example this) 1.9.10 is indeed the latest version.

Note as well that those are just warnings you could potentially igore.
However as your are facing other issues with the open-jdk implementation ignoring them is not an option for you.

PHP, remove from array?

Change your loop to:

foreach($this->registry->stockistCountries as $i => $value)
{
    if($value['country'] == 'UK'){
        $buffer .= '<option>UK</option>';
        $buffer .= '<option disabled>------------------</option>';
        unset($this->registry->stockistCountries[$i]);
    }

}
