About the standalone debug, we didn’t have developed it yet but we are looking on how to do it.
For the Release configuration :
Did you create your project from System Workbench or did you import it ?
In the first case, in the Project Properties > C/C++ Build, you have a configuration combo box to display your current configuration. A Release configuration with the correct optimisation and debugging level should editable here (don”t forget to set it active in “Manage Configuration” to use it)
If there is no Release configuration choice, in the “Manage Configuration” dialog, create a new configuration from the Debug one. Then set it active and modify the optimisation and debugging level options in C/C++ Build > Settings
Hope I did answer your problem.
