gcc problems with Fedora Core 3

**phldml3** · 06-10-2005

All,
Please excuse me, I'm rather new at working with C on LINUX. I'm trying to implement some code that will read information off of my weather station then post it to the web. Thought it would be as simple as running 'make' and then executing the code, but gcc came back with pages of errors. So I've stepped back to the simple 'hello world' code to familiarize myself with gcc.

My code is as follows:

Code:

#include <iostream>

using namespace std;

int main()
{
   cout<<"HEY, you, I'm alive!  Oh, and Hello World!\n";
   cin.get();
}

I'm also using the following makefile:

Code:

CC= gcc
LIBDIR= -I/usr/include/c++/3.4.2
SRC= test.c
OBJS= test.o
PROG= test

test:  ${OBJS}
           ${CC} -o ${PROG} ${SRC} ${LIBDIR}

When I run make, I get the following errors:

test.c:1:20: iostream: No such file or directory
test.c:3: error: syntax error before "namespace"
......

I've been unable to correctly characterize the header files locations so that the gcc recognizes it.

Thanks

1) This is not the general Linux support forum.
2) You're not programming in C at all. That's C++.

Like I said! I'm new at this

Ok, well I'm just telling you, you are in the wrong place for your question. You need the Fedora newsgroup or a basic "help me set up my linux box" site. The problem, as with your previous post on the same thing, appears to be that you don't have your compiler installed correctly.

I'd suggest looking for a linux forum or newsgroup.

So write it in C then

Code:

#include <stdio.h>
int main ( void ) {
  printf( "hello world\n" );
  return 0;
}

And since this is C, there's no need for LIBDIR

>test: ${OBJS}
Calling programs test in Linux/Unix is a bad idea, there's also a shell command of the same name.
Which if you invoke without parameters does nothing.

Code:

$ cat test.c
#include <stdio.h>
int main ( void ) {
  printf( "hello world\n" );
  return 0;
}
$ gcc -o test test.c
$ test
$ ./test
hello world
