[Boost-users] Execution problem moving libraries

Hi everyone.

I get a very tricky error with boost.thread. I can compile and execute 
perfectly a C++ program with the following comand line:
g++ -Wall -fPIC -pedantic -g -O3 -DDEBUG -march=native -std=c++0x 
-lboost_thread -o myExecutable myExecutable.cpp

But I have to move this software into another machine, and I thought it 
was possible to take dynamic libraries with it, in order to properly 
link them to the executable.
I have a structure like the following:
package
       |
     bin
       |- myExecutable
     etc
       |- libboost_thread.a
       |- libboost_thread.so -> libbost_thread.so.1.42.0
       `- libboost_thread.so.1.42.0

And performing a proper export of LD_LIBRARY_PATH, it seems I obtain a 
correct link:
ldd myExecutable
     ...
     libboost_thread.so.1.42.0 => ../etc/libboost_thread.so.1.42.0 
(0x002cd000)
     ...

But when I try to execute my software, I obtain the following error:
/home/user/myExecutable symbol lookup error: /home/user/myExecutable: 
undefined symbol: _ZTIN10__cxxabiv115__forced_unwindE

Do you have an idea of why this occurs?
Have I to compile boost libraries in an uncommon way to make this 
situation work?

Thank you.
