[Condor-users] condor_compile

["关中大侠" <969041723@xxxxxx>]

I tried to use the standard universe,and some one has told me that the condor-7.6.3-x86_64_rhap_6.1-updated-unstripped.tar.gz release can do this.

And I write a simple Helloworld like this:

in the source file called a.cpp:

-------------------------------------------

#include<iostream>

using namespace std;

int main(){

        for (int i=0;i<20;i++){

                cout<<i<<": hello world"<<endl;

                sleep(1);

        }

        return 0;

}

-----------------------------------------------

then,I compile it with the command:

condor_compile g++ a.cpp -o a

but I have the result:

Could anyone tell me how to overcome it? 

Thank you!
