Can't find <iostream>

Hello there,
I've been running in to a ton of problems lately. I'm in Vocational school, and I use Ubuntu on my computer there. I've been programming with the allegro library, and things were going fine. Then, when I went to compile a program I was making (a Pong game), Code::Blocks told me it couldn't find <iostream> and <string>. I compiled something like 10 minutes before that, and didn't do anything.

I went home, and tried the code on my Ubuntu on my laptop and I got the same problem. So I figured it as the code, and I wrote a simple hello world program to test my iostream. It didn't work. Here're the errors I got:

Code:

#include <iostream> using namespace std; int main(void){ cout << "Hello world!"; cin.get(); return 0; }

Errors:

Code:

when I compile the code for the Pong game I was making (I know there are bugs, I just wanted to compile and see if it would show the paddles -- I found out there are htings I need to fix before it works, but look at everything else)

Code:

#include <allegro.h> #include <iostream> #include <string> using namespace std; void Check_Null(BITMAP* Picture, string Type, string Error); int Get_Rand(void); int main(void){ cout << "This is a Pong game by Lorgon Jortle.

I have uninstalled Code::Blocks, gcc, g++, and tried installing other IDE's. Now I reinstalled gcc, g++ and Code::Blocks and it's still giving me errors.

Anybody have any ideas? I have the latest build-essential, and release.

Well, you do have <iostream> because line 44 of that file is

Code:

#include <bits/c++config.h>

and line 48 is the function call

Code:

_GLIBCXX_BEGIN_NAMESPACE(std)

so it seems to be that "c++config.h" file that you can't seem to access. Do you have a /usr/include/c++/4.3/i486-linux-gnu/bits/c++config.h file?

Lines 20-22 of /usr/include/bits/stdlib.h are

Code:

#ifndef _STDLIB_H # error "Never include <bits/stdlib.h> directly; use <stdlib.h> instead." #endif

so it looks like something is inappropriately #including that file and generating those errors. Not that that helps you.

I guess the next thing to try would be to "completely uninstall" build-essential and liballegro*** (whichever version you have), and reinstall them. (Assuming you installed an Ubuntu allegro package & didn't build it from source.)

Another thought -- could it be something as simple as that somehow your $PATH got messed up?

I think we all know a lot of times a 50 line compiler error is usally caused by the first line and then it just decays from there. your compiler obviously can't find that bits/c++config.h file so i would check your $PATH variable and make sure thats taken care of as well as making sure config.h isn't corrupted in some way. BTW bits/c++config.h: - Google Search google is still your best friend. check the first link and i bet you its related to your problem. cheers.

I've reinstalled gcc, g++, allegro, and code::blocks. Still the same problem. I've searched how to change the $PATH variable, but I still haven't found how. Will you please point me in the direction to do so, and not vaguely tell me "Google is my friend". I'm not ignorant, you know.

EDIT: I completely removed build-essential, liballegro4.2, and gcc, then reinstalled them. I still get the same error about bits/stdlib.h and bits/string.h and so on. Any other ideas?

Does GCC work when called from the command line?

Does a Hello World in CodeBlocks work?

Same errors doing gcc from terminal. The Hello World is the first one I showed up in post #1. I'll try a fresh hello world in Gedit, then try to compile it via terminal.

Code:

#include <iostream> using namespace std; int main(void){ cout << "Hello world, C++ works again.\n"; cin.ignore(1000, '\n'); cin.get(); return 0; }

Code:

lorgonjortle@laptop:~/Desktop/Test$ ls main.c lorgonjortle@laptop:~/Desktop/Test$ gcc main.c main.c:1:20: error: iostream: No such file or directory main.c:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘namespace’ main.c: In function ‘main’: main.c:6: error: ‘cout’ undeclared (first use in this function) main.c:6: error: (Each undeclared identifier is reported only once main.c:6: error: for each function it appears in.) main.c:7: error: ‘cin’ undeclared (first use in this function) lorgonjortle@laptop:~/Desktop/Test$ g++ main.c lorgonjortle@laptop:~/Desktop/Test$ ./a.out Hello world, C++ works again. lorgonjortle@laptop:~/Desktop/Test$

CRAZY! It worked when I did g++, but not gcc. Even when the code was main.c not .cpp. Let me try to compile the allegro stuff with g++....

EDIT: When I did it with g++, it compiled fine. This is the command I used:

Code:

g++ Collision.c `allegro-config --cflags` `allegro-config --libs`

Here was the code:

Code:

#include <iostream> #include <allegro.h> #include <string> using namespace std; bool Collision_Test(void); //Checks for collision void Check_Null(BITMAP* Test, string Type, string Error); //Tests bitmap to see if it recieved content int main(void){ cout << "Collision testing in preparation for Pong.

So I'm just using Geany, and I compile via the built-in terminal inside of it. Thanks for the help, guys/gals.

CRAZY! It worked when I did g++, but not gcc. Even when the code was main.c not .cpp. Let me try to compile the allegro stuff with g++....

EDIT: When I did it with g++, it compiled fine. This is the command I used:

so just to clarify lorgon, you were compiling a C++ program as a C program is that right.

for future reference C++ is supposed to be a superset of C (meaning it should compile pretty much any C code) as a valid C++ program. It doesn't do it very well, but it tries and i'm sure you'll get used to the ideosyncracies of both language especially when doing game coding like you are now. Many in the industry say C/C++ like its one language, but in fact they are two separate distinct languages. get used to that.

BTW, allegro is written in C not C++, so writting C++ code with the allegro lib you should compile it as C++, not C. which means calling g++ not gcc.

From the errors that you posted in #6

Code:

lorgonjortle@laptop:~/Desktop/Test$ gcc main.c main.c:1:20: error: iostream: No such file or directory main.c:3: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘namespace’ main.c: In function ‘main’: main.c:6: error: ‘cout’ undeclared (first use in this function) main.c:6: error: (Each undeclared identifier is reported only once main.c:6: error: for each function it appears in.) main.c:7: error: ‘cin’ undeclared (first use in this function)

it's obvious that the error is using the c compiler (and .c extension) on a file that includes <iostream>. But those are completely different from the errors you posted for your "Hello world" in #1:

Code:

so what did you do that produced those errors?

The longer list was what Code::Blocks gave me. The shorter was when I did it via terminal. I understand now though, I was using C++ code, and I thought it had to be compiled as C. Thanks for the help. :-)

It's just odd that it always worked before. Maybe it's the new upgrade that changed it so that wasn't allowed...
