求教在Mandrake下gcc的使用问题

tom

有谁在Mandrake 9下使用过gcc 编译程序的经验？
我安装了使用Mandrake 9 并使用gcc 编译一个C++的例子，但编译有错，我的C++程序如下：

#include <iostream.h>
int main()
{
cout<<"test\n\n";
return 0;
}
编译后显示：
[root@localhost tmp]# gcc test.cc
In file included from /usr/include/c++/3.2/backward/iostream.h:31,
                 from test.cc:1:
/usr/include/c++/3.2/backward/backward_warning.h:32:2: warning: #warning This file includes at least one deprecated or antiquated header. Please consider using one of the 32 headers found in section 17.4.1.2 of the C++ standard. Examples include substituting the <X> header for the <X.h> header for C++ includes, or <sstream> instead of the deprecated header <strstream.h>. To disable this warning use -Wno-deprecated.
/tmp/cc3HLE0n.o: In function `main':
/tmp/cc3HLE0n.o(.text+0x19): undefined reference to `std::cout'

不只到为什么会出这个问题？然后我将程序修改为：

#include <iostream>

int main()
{
cout<<"test\n\n";
return 0;
}

编译后显示：
[root@localhost tmp]# gcc test.cpp
test.cpp: In function `int main()':
test.cpp:5: `cout' undeclared (first use this function)
test.cpp:5: (Each undeclared identifier is reported only once for each function it appears in.)
[root@localhost tmp]#

是不是在Mandrake 9下gcc不支持这种标准的C++程序？

请指点迷经。

谢谢。

编译cpp的相应命令是g++，gcc是专门编译c代码的。
oops，偶感觉g++比较慢。

我用g++试过，显示同样的错误,当我敲入命令‘gcc -v’时，显示：
Reading specs from
/usr/lib/gcc-lib/i586-mandrake-linux-gnu/3.2/specs
Configured with:
../configure
--prefix=/usr
--libdir=/usr/lib

--enable-__cxa_atexit
--enable-languages=c,c++,ada,f77,objc,java
--host=i586-mandrake-linux-gnu
--with-system-zlib
Thread model: posix

look at the line:
--enable-languages=c,c++,ada,f77,objc,java
does this mean that it support c,c++,ada,f77,objc, and java?

真是搞不清，闹不明。

你直接用printf不就行了。非要弄个cout。
