Hi,

I am newbie to c/cpp and I have linking and/or loading shared library 
problem.

I can not link with dynamic libraries.

Thanks for your help in advance,
Tamas

[violin]$ ldconfig -p | grep libboost_program_options
         libboost_program_options.so.1 (libc6) => 	
                   /usr/lib/libboost_program_options.so.1

*** 2 ***
As I do not have the file /usr/lib/libboost_program_options.so.1 I 
created a link:
libboost_program_options.so.1 -> 
libboost_program_options-gcc-1_33_1.so.1.33.1

Compiling my src file
[violin]$ g++ -Wall -I /usr/local/include/boost-1_33_1 -c test.cpp

[violin]$ g++ -Wall -o test test.o 
/usr/local/lib/libboost_program_options-gcc-1_33_1.so.1.33.1

[violin]$ ./test
./test: error while loading shared libraries:
