i have indeed found that the problem comes from a library that is use.

I create a very small class : 

in toto.h : 

class Toto
  {
    int x;

  public:
    Toto(int i);
  };

in toto.cpp :

#include "toto.h"

  Toto::Toto(int i)
  {
    x = i;
  }
in test.cpp : 

#include "../src/toto.h"

int main ()
{
  Toto tt(2);
  return 0;
}

i link toto.cpp in my_lib.so

i compile test.cpp with : 

g++ bin/libavisynth.so -L/home/torri/local/lib -lstlport_gcc
-L/home/torri/local/lib -lboost_thread-gcc-mt-1_31 -Wall -O2 -o bin/test
../../test/test.cpp

when i exec ./bin/test, i have:

./bin/test: relocation error: ./bin/test: undefined symbol: _ZN4TotoC1Ei

There's no problem if i link directly with toto.so and not my_lib.so
There's no problem if there's no parameters in the constructor
all the libs have been compiled with the same compiler (g++ 3.3.1)
nm ./bin/my_lib.so |grep _ZN4TotoC1Ei returns 001e8950 T _ZN4TotoC1Ei

afaik, gdb or valgrind have not helped me much.

i'm completely lost. Why this small class could not be used ?
