C++ Library Question

[darkscript]

I've come from developing programms in c++ on the windows box. I'm not used to the structure and layout of the STL and I feel greatly more comfortable with <iostream> <fstream>. I've been using them blindly since all of my programming books refer to them instead of the STL. So I dont even know if there platform dependent. Heck they could even be part of the STL.

So, what I want to know is,

Can I use this library on linux?

The Standard Template Library (STL) is part of the C++ standard, so all implementations of C++ should support them. It includes stuff like templated containers ("vector", "list", "set", etc.), their iterators, algorithms and utilities that are used on those containers (sort, copy,etc.) , templated function objects and their associated stuff, etc. The classes in the STL are templated, meaning that they must be specialized for some specific type -- i.e. list<int>. The iostream library and the standard C library are not part of the STL since they do not involve templated types.

For a very technical reference of the STL, go here; for a simple reference of the classes, go here.

yes, you can use iostream and fstream in linux

<iostream> does a few thing, the main the is cin and cout that is all, but yerah it is standard build when I make a program, but so is string

So now that I know that this library is compatible with linux, How can I get it to work with gcc? In otherwords where do I put the header files and what configuration files must I change.

You don't need to change anything. This is standard C++. Just put #include <iostream> or whatever; and any C++ compiler (especially GCC-C++) should have all the headers and be able to compile it without any extra action.

Hi,

It's been some while since the last post here. But I'm also trying to use the stl library on fedore (FC4). But just doing the following small test doesn't work:

#include <iostream>
#include <string>
using namespace std;
int main(){
string naam;
cout << "Geef je naam op: ";
cin >> naam;
cout << endl << "Je naam was: " << naam;
exit 0;
}

the output I get when compiling with gcc is:

[root@localhost Algoritmen]# gcc stl_test.c -o stl_test
stl_test.c:1:20: error: iostream: No such file or directory
stl_test.c:2:18: error: string: No such file or directory
stl_test.c:3: error: syntax error before ‘namespace’

stl_test.c:8: error: ‘endl’ undeclared (first use in this function)
stl_test.c:9: warning: incompatible implicit declaration of built-in function ‘exit’

So it does not seem to me like stl is standaard installed :s. I have downloaded the stl and placed it in the subfolder stl_lib. Does anyone know how I have to compile my files so that gcc knows how to check in this directory for the stl header files?

thanks in advance

For C++, you should give your files ".cpp" extension and use g++ instead of "gcc"

Ah! thanks alot :-)

I wish they would port dev c++ for us. that would be a great tool. I know its out now, but it uses the qt library.

Try Anjuta if you are shy to use QT libraries, if not, KDevelop is another great GUI, not forgetting Eclipse with C/C++ plugin.
