}


int main()
{
 ra_myappl myappl;
 
 myappl.init();
 myappl.scan(); 
 myappl.close();
}

Create file /usr/local/pwrp/cpp/src/appl/ra_myappl.h (this file just needs to exist, it should be empty)

On the terminal 

$ sdf cpp
$ cd /usr/local/pwrp/cpp/src/appl/
$ g++ -g -c ra_myappl.cpp -o $pwrp_obj/ra_myappl.o -I$pwr_inc -DOS_LINUX=1 -DOS=linux -DHW_X86=1 -DHW=x86 -DOS_POSIX
$ g++ -g -o $pwrp_exe/ra_myappl $pwrp_obj/ra_myappl.o $pwr_obj/pwr_msg_rt.o -L$pwr_lib -lpwr_rt -lpwr_co -lpwr_msg_dummy -lrt -pthread

On Proview

  • Shift+Ctrl+B Node + B
  • Tools -> Runtime Monitor
  • Start Runtime
  • File -> Start Runtime Navigator
  • right arrow key Database
  • right arrow key plant
  • MB3 curve Object Graph


On the terminal 

$ ra_myappl

Automatically Starting the Application When Proview Starts

  • Open the file /usr/local/pwrp/cpp/bld/common/load/ld_appl_***.txt
  • In the User applications section, add the line: 
 ra_myappl, ra_myappl, noload, run, ra_myappl, 12, nodebug, ""
