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, ""
