System :: problems with gcc1.dsl



well, the topic description pretty much said it all.
i downloaded, checked the md5sum and installed gcc1.dsl (which went really well). i wrote a short hello_world and tried to compile it. the computer thought for about 10 seconds and then complained. here is the program and the complaint, incase anybody's interested:

#include <iostream>
using namespace std;

int main()
{
cout << "hello world" << endl;
return 0;
}

i suppose these undefined reference things could mean, that the standard library isn't correctly installed. but it doesn't complain about my #include instruction.

does anyone know what's up?

howlingmadhowie, take a look at this previous g++ post.  I believe you need to compile c++ programs with g++ rathr than gcc.  You didn't mention what comand line you were using to compile your program, but try:

g++ -o hello hello.cpp
that was it, many thanks :)

now why didn't i find that page while searching the forum?...
