gcccilkcilk-plus

error in compiling cilk plus with gcc-4.7

I get the following error

main.c:107:2: internal compiler error: in extract_for_fields, at cilk-spawn.c:1857
}

and the relevant lines are:

cilk_for (index = 0; table_name[index]!=NULL; ++index )
{
      /* some work*/
}

Line 107 corresponds to the closing braces of cilk_for loop.

Any help is appreciated!

Solution

  • What I did above was not a valid cilk_for loop because the cilk_for loop must test the control variable. Also one must be able to predict how many time the loop will run and in this case this is not possible. So the correct version for this will be 

    int count=0;
while(table_name[count]!=NULL)
    count++;
cilk_for (index = 0; index!=count; ++index )
{
      /* some work*/
}
