I have qnxsdp-6.5 installed on my host pc (Vista), and installed QNX on VMware player 4.0. 
run qconfig on host pc:

QNX Installations

  Installation Name: QNX Software Development Platform 6.5.0

QNX Installations

Installation Name: QNX Software Development Platform 6.5.0
Version: 6.5.0
Base Directory: /usr/qnx650/
QNX_Host: /usr/qnx650/host/qnx6/x86
QNX_target: /usr/qnx650/target/qnx6

The default c++ QNX project can be compiled and run from IDE OK, and I can see the program out "Welcome to the QNX 
Momentics IDE". but when I transfer the executable file to qnx, and run it from the terminal, I got memory fault (core 
dumped) message. 

If I transfer the source file (.cc) files to qnx and compile the source file on QNX instead of IDE, the binary file can 

run without memory fault.
