 Thanks for your reply!   I tried it with g++ and I got the following
 error
 
 test.cpp:
 
 void operator delete[](void * pPtr) throw()
 {
 }
 
 gcc -c test.cpp
 
 g++ -lc -lstdc++ -shared test.o -o test.so
 /usr/bin/ld: test.so: undefined versioned symbol name operator 
 delete[](void*)@@GLIBCPP_3.2
 /usr/bin/ld: failed to set dynamic section sizes: Bad value
 
 Could you tell why?  I did not get any error in gcc 3.1.
 
 Thanks
 
 Philip

 If you are trying to make a shared library, the commands are
 
     gcc -c -fPIC test.cpp
     g++ -shared -fPIC test.cpp -o test.so
 
 as described in the FAQ here:

 There's no need for the two -l... switches. If you drop them, everything 
 works fine. g++ will do all this stuff for you, there's no reason to make 
 it more complicated than necessary!
