c++

what I need to compile a c++ fille on Linux, as far as I know I've created my file with extension cpp by using the text editor such as KWirter, and then compile it with gcc, but it gives me long error message

/tmp/ccb5v3PS.o: In function `__static_initialization_and_destruction_0(int, int)':

1.cpp:(.text+0x23): undefined reference to `std::ios_base::Init::Init()'

/tmp/ccb5v3PS.o: In function `__tcf_0':

1.cpp:(.text+0x6c): undefined reference to `std::ios_base::Init::~Init()'

/tmp/ccb5v3PS.o: In function `main':

1.cpp:(.text+0x8b): undefined reference to `std::allocator<char>::allocator()'

Try compiling it with g++ instead of gcc.

 

Welcome aboard! :)

after compiling the code ......what I need to write to see the outputs on the shell screen, Is it the same as Fortran ./a.out

[Greg2]

Yes, you would execute the file with

./a.out

You may need to make it executable first with

chmod +x a.out

You could also specify a name using the -o option

g++ file-name -o new-file-name

for more info, see 'man g++'.
