Hey,

New member here because I haven't been able to find any good info on how to create C++ programs for the iPhone/iPod Touch.

I just want to make a simple "Hello, world!" programme on the iPod itself and <b>not</b> using the toolchain.

I found a thread discussing how to do it in C

//main.c
#include <stdio.h>

int main()
{
printf( "Hello, world!n" );
return 0;
}

then type into terminal

gcc main.c -o main
ldid -S main
chmod 0775 main
./main

and that works perfectly but when I try to make a C++ "Hello, world!" I get header errors.

// main.cpp
#include <iostream>

int main()
{
std::cout << "Hello, world!n" << std::endl;
return 0;
}

Now, when I type into terminal:

g++ main.cpp -o maincpp

I get the following errors;

main.cpp:1:20: error: iostream: No such file or directory
main.cpp: In function 'int main()':
main.cpp:5: error: 'cout' is not a member of 'std'
main.cpp:5: error: 'endl' is not a member of 'std'

Please could someone help me out with this problem as I want to learn how to program in C++ but because I have lots of homework during the evenings I don't get much time to use a C++ compiler on my desktop.

I would also prefer to code in C++ because I've already got to grips with the basics and don't really want to learn C.

Thanks.

Come on people, there are bound to be some good programmers out there who can help me.

Clearly you are missing STL header files.

Once you install the missing headers, you have to ckeck if the lib is installed.

[decky1990]

the standard library files are not missing they are just in other subfolders within /var/include

Problem is whenever I try to link the compiler to the directory I get everlasting errors. The compiler finds iostream alright when I link it using the -I"/var/include/c++/4.0.0/" option but it can't find the header files stated within iostream.

Another question: am I searching for iostream or iostream.h? And which compiler should I be using e.g. gcc, c++, g++, arm-apple-darwin9-g++ etc?
