[Click] Doing some research

[Bobby Longpocket]

Maybe you ran configure --fix-includes again after you made the change?  The file that you are modifying is the result of running configure, so your changes will get clobbered if you run configure again.  Check your file again to verify that lines 150 and 176 include the int pointer casts.

Click patchless has a problem with 2.6.37.  In radix-tree.h there's a call to a macro that ends up trying to dereference a void*.  The C++ compiler doesn't like this.  You can apply the following changes to click/include/click-linuxmodule/include1/linux/radix-tree.h to make more progress with your compilation:




150c150

<       return rcu_dereference(*pslot);

---

>       return (void *)rcu_dereference(*(int **)pslot);

176c176

<       rcu_assign_pointer(*pslot, item);

---

>       rcu_assign_pointer(*(int **)pslot, (int *)item);

ok applied the reference patch to click and now.... still no joy
