Hi all, I build a native C++ compiler - version 4.1.1. I then tried to execute a simple hello world C++ program. when compiled with g++, it gives me the following error: ./a.out: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory but when i use the command line driver $gcc 1.cpp i get the following errors. /tmp/cc2wk6Uk.o(.text+0x23): In function `__static_initialization_and_destructio n_0(int, int)': : undefined reference to `std::ios_base::Init::Init()' /tmp/cc2wk6Uk.o(.text+0x3e): In function `__static_initialization_and_destructio n_0(int, int)': : undefined reference to `std::ios_base::Init::~Init()' /tmp/cc2wk6Uk.o(.text+0x90): In function `main': : undefined reference to `std::cout' /tmp/cc2wk6Uk.o(.text+0x95): In function `main': : undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std ::operator<< <std::char_traits<char> >(std::basic_ostream<char, std::char_traits <char> >&, char const*)' /tmp/cc2wk6Uk.o(.text+0x9d): In function `main': : undefined reference to `std::basic_ostream<char, std::char_traits<char> >& std ::endl<char, std::char_traits<char> >(std::basic_ostream<char, std::char_traits< char> >&)' /tmp/cc2wk6Uk.o(.text+0xa5): In function `main': : undefined reference to `std::basic_ostream<char, std::char_traits<char> >::ope rator<<(std::basic_ostream<char, std::char_traits<char> >& (*)(std::basic_ostrea m<char, std::char_traits<char> >&))' /tmp/cc2wk6Uk.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0' collect2: ld returned 1 exit status I did not have anyproblems while building the compiler. Can any one tell me where i am going wrong!!! Regards, Rohit
