Also try running ldd /home/bkebianyor/eclipse-workspace/Model_LLDB_Debugger/Debug/libModel_LLDB_Debugger.so
That will list dependencies that the loader can and cannot resolve. A possible alternative to a plugin could be to use "breakpoint set -p", which does a regular expression match on the source, so you can set a breakpoint based on the text of an annotation. You could wrap this in a python script if you want to make it into a custom command. Ted -- Qualcomm Innovation Center, Inc.
