Question Newbie Q

What is the comand to compile a c++ code in Unix. I have only used Borland C++ on win but have heard that UNIX has a integrated compiler.

Yes there is a compiler in Unix, its called g++

g++ [option | filename ]

g++ is a script to call gcc with options to recognize C++. gcc processes input files through one or more of four stages: prepro-cessing, compilation, assembly, and linking.

C++ source files use one of the suffixes `.C', `.cc',`.cxx', `.cpp', or `.c++'; preprocessed C++ files use the suffix `.ii'

In g++ options must be separate: "-dr " is quite different from `-d -r ' and so on..

For more information check your g++ man pages

Error message

I tried to run g++ ut got an error about <iostream.h>

As I understod it is supposed to be located in /usr/include but it is not there. Have i got it wrong?

The error msg I got is:

hello.cpp: In function `int main ()':
hello.cpp:5: no match for `_IO_ostream_withassign & = const char[13]'
/usr/include/g++-3/iostream.h:243: candidates are:
_IO_ostream_withassign &_IO_ostream_withassign:Smilieperator= (ostream &)
_IO_ostream_withassign &_IO_ostream_withassign:Smilieperator=
(_IO_ostream_withassign &)

and the source code is:

#include <iostream.h>

main ()
cout >>"Hello World\n";

return 0;

Error Error

Ok, now I do got error:

hello.cpp: In function `int main ()':
hello.cpp:5: `cout' undeclared (first use this function)
hello.cpp:5: (Each undeclared identifier is reported only once for each
function it appears in.)

`cout' undeclared? I don't get this....

Bug Got it working

Finally I got it working!
Feels quite embarrasing to put the error from one of the most simple program ever on the web. ut for all newbies - Watch ad learn.

The rigth code is:

#include <iostream.h>

int main()
cout << "Hello World!\n";

return 0;

Take care!
