error running a compiled C++ file (uses OpenGL). Error: “Inconsistency detected by ld.so: dl-version.c: 224”

Question

I created a simple opengl file in cpp. It works on the University computer. I\'m able to compile the file, but i can not run the compiled file. The error I get is:

It looks that some thing has changed by some Ubuntu 13.10 sw updates. I had also code that has compiled and run without problem and just one day I started to get same Assertion `needed != ((void *)0)' failed! error but only if I compiled my code again with current gcc/lib versios.

After debugging I found out that the assert error comes from /lib/i386-linux-gnu/ld-2.17.so

      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);

It is said that this should never happen and it does not say what is needed but not found. Some gdb work and i found that it needs libpthread.so.0 . The good question is that why /usr/bin/ld linker linking application and ld.so disagree about need of this library.

I did not intentionally use libpthread but from somewhere i got to my link map reference to __pthread_key_create@@GLIBC_2.0 I don't know where this comes but it may cause need of libpthread.so without adding NEEDED libpthread.so.0 as follows on objdump -p :

Dynamic Section:
 NEEDED               libglut.so.3
 NEEDED               libGLU.so.1
 NEEDED               libGL.so.1
 NEEDED               libstdc++.so.6
 NEEDED               libgcc_s.so.1
 NEEDED               libpthread.so.0
 NEEDED               libc.so.6

I did not find a root cause of this problem but least workaround. You need link your code with -pthread option and have some dummy call to this library .

Define in you Makefile libs

 -lglut -lGLU -lGL -lm  -pthread

Then include some dummy function just refer some libpthread function to make linker link it and you get the NEEDED libpthread.so.0 and then ld.so is hap.

#include 
void junk() {
  int i;
  i=pthread_getconcurrency();
};

This helped for me, i hope that it helps.
