Cannot find ldl lnsl lpthread lrt when buildling?

I am trying to build the RTI perftest in an i86 QNX architecture. When I try to build the makefile that I generated, I get the following:

Checking directory obj/i86QNX6.6qcc_cpp4.7.3/Release
Checking directory ../bin/i86QNX6.6qcc_cpp4.7.3/Release
qcc -V4.7.3,gcc_ntox86 -Y_cpp -lang-c++ -m64 -Wall -o ../bin/i86QNX6.6qcc_cpp4.7.3/Release/perftest_cpp obj/i86QNX6.6qcc_cpp4.7.3/Release/test.o obj/i86QNX6.6qcc_cpp4.7.3/Release/testPlugin.o obj/i86QNX6.6qcc_cpp4.7.3/Release/testSupport.o obj/i86QNX6.6qcc_cpp4.7.3/Release/Property.o obj/i86QNX6.6qcc_cpp4.7.3/Release/RTIDDSImpl.o obj/i86QNX6.6qcc_cpp4.7.3/Release/perftest_cpp.o -L/opt/RTI/ndds.5.1.0/lib/i86QNX6.6qcc_cpp4.7.3 -lnddscppz -lnddscz -lnddscorez -lm -lsocket  -lpthread -lnsl -lrt -L/usr/lib/nptl

make: *** [../bin/i86QNX6.6qcc_cpp4.7.3/Release/perftest_cpp] Error 1

I am not to familiar with QNX and its libraries, but when I remove those flags I get a ton of errors. Any tips on how to build the perftest for QNX or dealing with this error would be great, thanks!

Solution

My makefile has the following build line which resolves all symbols and results in a running executable:

qcc -o ../bin/i86QNX6.6qcc_cpp4.7.3/Release/perftest_cpp 
  obj/i86QNX6.6qcc_cpp4.7.3/Release/test.o 
  obj/i86QNX6.6qcc_cpp4.7.3/Release/testPlugin.o 
  obj/i86QNX6.6qcc_cpp4.7.3/Release/testSupport.o 
  obj/i86QNX6.6qcc_cpp4.7.3/Release/RTIDDSImpl.o 
  obj/i86QNX6.6qcc_cpp4.7.3/Release/perftest_cpp.o
  -L/opt/RTI/rti_connext_dds-5.2.3/lib/i86QNX6.6qcc_cpp4.7.3
  -lnddscppz -lnddscz -lnddscorez -lm -lsocket
  -V4.7.3,gcc_ntox86 -Y_cpp -lang-c++ -Wall

Note that it has none of the libraries that you mention.
