[plexil-support] Building an application with both Executive and Interface Adapters
|

Dear Plexil Support,
Another rookie question for you.
I am trying to figure out how to build and use an interface adapter from within the same application as the executive (as opposed to linking to a shared library). To that end, I have been modifying UniversalExec.cc to try to use the code from example/sample-app (the "SampleAdapter" class). In summary, it seems that I can build the code, explicitly create a SampleAdapter, but when the plan runs, it doesn't know where to go for the commands and lookups.
The modifications to UniversalExec.cc are as follows:
<snip>
#include "SampleAdapter.hh"
<snip>
// construct the application
PLEXIL::ExecApplication _app;
/////////////////////////////////////////////////////////////////////////////////////////////
// CL: Try to manually add a SampleAdapter adapter
std::cout << std::endl << "YO! About to add a SampleAdapter!" << std::endl;
SampleAdapter myAdapter(_app.getInterfaceManagerReference(), configElt);
_app.getInterfaceManagerReference().addInterfaceAdapter(myAdapter.getId());
std::cout << "Hmm... I wonder if that worked?" << std::endl << std::endl;
/////////////////////////////////////////////////////////////////////////////////////////////
// initialize it
std::cout << "Initializing application" << std::endl;
<snip>
I have made one modification to example/sample-app/plans/plan1.pli, which is to make the start condition always true, otherwise it doesn't do anything (more on this below). When I run the application using this plan, I get:
Reading interface configuration from plans/dummy-config.xml
YO! About to add a SampleAdapter!
[SampleAdapter] created.
Hmm... I wonder if that worked?

ERROR: ../utils/Id.hh:493: Cannot remove an invalid Id<N6PLEXIL16InterfaceAdapterE>.
AllInOneSandbox: Error.cc:89: void Error::handleAssert(): Assertion `false' failed.
The fact that I get "Speed and size: UNKNOWN UNKNOWN", and the fact that it habitually fails the notional start conditions in the original .pli, leads me to believe that the Commands and Lookups are going nowhere instead of being handled by SampleAdapter. No idea what the invalid ID is all about.
The above result is using the configuration example/dummy-config.xml. If I try the same thing with the configuration example/sample-app/interface-config.xml, I get:
YO! About to add a SampleAdapter!
[SampleAdapter] created.
Hmm... I wonder if that worked?
Initializing application
ERROR: unable to initialize application
ERROR: ../utils/Id.hh:493: Cannot remove an invalid Id<N6PLEXIL16InterfaceAdapterE>.
AllInOneSandbox: Error.cc:89: void Error::handleAssert(): Assertion `false' failed.
I assume it's unable to initialize because it's looking for libSampleAdapter.so, which I am explicitly trying not to use. Same invalid ID error as above.
I would really appreciate some help on how to create an all-in-one application. Thanks in advance.
