I will try this. Is this a flag that I have to set in cmake, or can I
also use this in the makefile?

The constructor of the RTIambassador is called, but fails with an
exception. I assume that therefore the destructor is called for cleanup...

I already did this, by adding the following macro to the cpp file:

#define dbg \
    { \
      FILE *logfiletmp = fopen("out2.txt","at"); \
      fprintf (logfiletmp, "DBG: %s::%s::%d\n", __FILE__, __FUNCTION__, 
__LINE__); \
      fclose (logfiletmp); \
    }


Adding dbg commands to several lines in the code, I see which lines are
executed (I had to print it to a file, as console output is somehow lost
within xplane).
See attached PDF for the code, and here is the output:

So, for me everything looks OK.

In execution outside xplane, I get additionally:
DBG:
d:/home/patrick/eclipse/certi/certi/libRTI/RTI1516ambPrivateRefs.cpp::executeService::212
DBG: d:/home/patrick/eclipse/certi/certi/RTIA/RTIA.cc::RTIA::49

DBG:
d:/home/patrick/eclipse/certi/certi/libRTI/RTI1516ambPrivateRefs.cpp::executeService::214

In xplane, I get the same lines, but after executeService::200 it
diverges due to the error.

I will try to compile it with the TCP flag. If this doesn't work, I may
ask the xplane developers, if they have an idea (e.g. if xplane doesn't
allow opening new processes).
