From http://www.qnx.com/developers/docs/6.3.0SP3/neutrino/utilities/q/qcc.html , I understand that QCC compiler should 
be a built in compiler in QNX Neutrino RTOS but I am constantly getting error as follows:

/bin/sh : QCC: cannot execute - No such file or directory

whenever I try to compile my program using the QCC compiler on terminal on QNX RTOS

Do we have to separately download QCC compiler and if yes please give me the download link

Thanks!
