Thanks Guys, works for me now too.  For completeness, here's the minimal working example without dragging in all of core.p4.
Regards,

action NoAction() {}
control foo() {
    action a(in bit<8> x) {}
    table t {
        actions = {
            a(5); // binding a's parameter x to 5
        }
    }
    apply {}
}

This looks wrong, this is not a p4-14 program.

This works for me.

#include <core.p4>
control foo() {
   action a(in bit<8> x) {}
   table t {
       actions = {
           a(8w5); // binding a's parameter x to 5
       }
   }
   apply{}
}

Hello P4,

I'm trying and failing to construct a minimal error-free example of a table in a control block.

AFAICT from the p4-16 spec, this code is valid:

  $ cat dummy.p4
  control foo() {
      action a(inout bit<8> x) {}
      table t {
          actions = {
              a(5); // binding a's parameter x to 5
          }
      }
  }


Building this code returns the following error:
  $ p4c -c dummy.p4
  dummy.p4(8):syntax error, unexpected }, expecting ACTION or CONST or TABLE
  }
  ^
  error: 1 errors encountered, aborting compilation


Can someone please show the fix needed to make this code compile?

Thanks,
-steve
