gcc doesn't know <iostream> ?!

gcc doesn't know <iostream> ?!

[Christine Tobler]

Hello,

I'm not sure this is the right address but I just can't get gcc to compile
any program using <iostream>, I tried everything I can think of.

When I try to compile just this:

#include <iostream>
using namespace std;

int main()
{
	//nothing in here!
}

it returns:

gcc -g -Wall -o hello.exe hello.cc
C:\WINDOWS\TEMP/cc2c06fb.o: In function
`Z41__static_initialization_and_destruction_0ii':
C:/PROGRA~1/MINGW/include/c++/3.2/iostream:62: undefined reference to
`std::ios_base::Init::Init()'
C:/PROGRA~1/MINGW/include/c++/3.2/iostream:62: undefined reference to
`std::ios_base::Init::~Init()'
C:\WINDOWS\TEMP/cc2c06fb.o: In function `main':
C:/Eigene Dateien/Tis/cpp/hello.cc:5: undefined reference to
`__gxx_personality_v0'

Compilation finished at Mon Apr 12 23:24:15

I'd be VERY happy if you could help me, I've been trying to get this working
for hours.

PS: Here's all the system info I could think of as might be useful:

I got gcc with MinGW32 2.0.0.3, when I do gcc -v there appears:

C:\WINDOWS>gcc -v
Reading specs from C:/PROGRA~1/MINGW/BIN/../lib/gcc-lib/mingw32/3.2/specs
Configured with:
../gcc/configure --with-gcc --with-gnu-ld --with-gnu-as --host=
mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --en
able
-languages=f77,c++,objc,ada --disable-win32-registry --disable-shared
Thread model: win32
gcc version 3.2 (mingw special 20020817-1)

and with ld -v:

C:\WINDOWS>ld -v
GNU ld version 2.13

I got this error on two computers, one with Windows 98 and one with Windows
XP.

You need:

g++ -g -Wall -o hello.exe hello.cc

C++ code must be linked using 'g++', *not* 'gcc' . 'gcc' only links
    with the C runtime and libraries, it does not link in the C++
    libraries.
