Hi all,
I am sorry to ask a question probably simple, but I can't solve this
problem.
I am new with C++ and I tried to run the first simple program to get
started.
The program is "Hello World":
#include <iostream.h>
// This program prints "Hello, World."
main()
{
cout << "Hello, World.\n";
return 0;
}
I called it primo.c, then I tried to run it:
I think that gcc assumes that files with .c extension are plain C files.
Try using a .cc extension.
$ gcc primo.c
primo.c:1:22: error: iostream.h: No such file or directory
primo.c: In function 'main':
primo.c:5: error: 'cout' undeclared (first use in this function)
primo.c:5: error: (Each undeclared identifier is reported only once
primo.c:5: error: for each function it appears in.)
I then tried to link the library iostream.h:
$ gcc -Wall -I/usr/include/gcc/darwin/3.3/c++/backward primo.c
In file included from primo.c:1:
/usr/include/gcc/darwin/3.3/c++/backward/iostream.h:32:20: error:
iostream: No such file or directory
In file included from primo.c:1:
/usr/include/gcc/darwin/3.3/c++/backward/iostream.h:34: error: parse
error before 'std'
primo.c:4: warning: return type defaults to 'int'
primo.c: In function 'main':
primo.c:5: error: 'cout' undeclared (first use in this function)
primo.c:5: error: (Each undeclared identifier is reported only once
primo.c:5: error: for each function it appears in.)
In the second output line, the compiler seems to tell me that it cannot
find iostream.h, but if i execute the ls command iostream.h is there:
$ ls /usr/include/gcc/darwin/3.3/c++/backward/iostream.h
/usr/include/gcc/darwin/3.3/c++/backward/iostream.h
I also tried to run primo.c with iostream.h in the same directory but it
gave me the same output of `$ gcc primo.c'
I know that this is not exactly a X11 problem, but I hope you can help
me too.
I work on a iBook 12'' PPC G4 1.33GHz, Tiger 10.4.10. I have installed
XCode 2.4.1.
Bye
Maurizio
