Re: [Condor-users] condor_compile

["Koller, Garrett" <kollerg14@xxxxxxxxxxxx>]

I think the problem is that condor_compile doesn't support system calls and sleep functions since a checkpoint during a sleep function would have indeterminate results.  See Section 1.4 of the Condor manual for more information on the limitations of checkpointing programs: http://www.cs.wisc.edu/condor/manual/v7.6/1_4Current_Limitations.html .  To run this program in Condor with the sleep function, you'll have to compile it without condor_compile and run it in the vanilla universe.

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!
