Can you post a small program that produces this effect?

Try 'gnu.g++.*' newsgroup hierarchy. And if you'd like to continue
posting here, I strongly suggest starting with FAQ list. You can find
it here: http://www.parashift.com/c++-faq/ (section 5 is *very* useful,
especially question 5.8)

Can you post a small program that produces this effect?



Cheers,



- Alf

This is the test program which i am trying to compile . using g++ -Wall test.cpp

#include <iostream>
using namespace std;
int main()
{
cout<<"Hello World!\n";
cin.get();
}

For what it is worth, it compiles fine with g++ 4.2.2.



The errors you are getting look a lot like the sort you get when a

header you are including requires that other headers be included

before. (For example, in Unix contexts, there are lots of headers

that assume you've included <sys/types.h> first.)



Unfortunately, I'm not familiar enough with the content of the

standard headers to say what is missing.



Is there any chance that you can install a different g++ version,

since you say this is a known bug with your version?

Drew Lawson So risk all or don't risk anything

You can lose all the same

I will install a different g++ version, looks like there is no solution to fix this.
