Running that symbol through c++filt on a Mac gives the following
unmangled name:

woz$ c++filt __ZNSs4_Rep20_S_empty_rep_storageE
std::string::_Rep::_S_empty_rep_storage

Doing a web search on that implies that you need to link against
libstdc++, so try adding this to the Makefile that builds simDetectorApp:
    OP_SYS_LDLIBS += -lstdc++

If that fixes it on Darwin there will need to be some adjustments to
make it cross-platform.
