Hi,

Could you post the full source code, or better, a subset of your current example that reproduces the problem? In your code above, several parts are missing like a systemc header include, class vcn_lcm, if_int definition etc.. and compilation gives also errors on missing scope like sc_core for sc_out.

On a side note, this is a UVM-SystemC/SCV forum whereas your problem is purely SystemC related.
