I'd like to compile a model with the OPC UA interface, as described in Section 6.3 of the system documentation.

1) Is there a step by step documentation on how to merge solver_main.cpp (c_runtime), compile the solver and also how to build OpenModelica simulations with the OPC UA server included?

2) The most recent version of solver_main.cpp in branches/OPC/c_runtime is for 1.7.0 RC1. In the meantime, solver_main.cpp has considerably changed. Nonetheless, is it possible (and safe) to patch the current version and add function calls for opc_ua_init, opc_ua_deinit and opc-ua_new_iteration? What are the current equivalents for the function arguments?
