Subject: [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:
       |- myExecutable
       |- libboost_thread.a
       |- ->

And performing a proper export of LD_LIBRARY_PATH, it seems I obtain a
correct link:
ldd myExecutable
     ... => ../etc/

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.
