QNX Terminal Workflow Setup (Momentics + VMware + SSH)

---

1) Creating the QNX C Project

Inside Momentics:

• Login to workspace
• Create New → QNX C Project
• Select predefined template (e.g., Hello World)

This generates:

.project
.cproject
Makefile
src/Demo.c

These predefined files configure:

• Cross compilation toolchain
• Target architecture (x86_64)
• Debug build configuration
• Output folder structure

---

2) Creating the QNX VM with SSH Support

We created the QNX VMware target using Momentics.

During Target Creation, we added SSH properties under:

Extra Options

🔐 SSH Extra Options Used

--ssh-ident=none --sshd-pregen=yes --getip --users=root/root

🧠 What These Options Do

Option	Purpose
--ssh-ident=none	Enables SSH without requiring public key file
--sshd-pregen=yes	Pre-generates SSH host keys
--getip	Enables DHCP networking
--users=root/root	Creates root user with password root

This ensures:

• SSH server is included in image
• Networking works automatically
• We can login via SSH from host
• VM gets IP address dynamically

After creation, the VM boots and networking is verified using:

ifconfig

Example output:

vmx0:

inet xxx.xxx.xx.xxx

---

3) Modifying the Source File

Modified:

src/Demo.c

Example:

#include <stdio.h>

int main() {
    printf("Hello from TERMINAL WORKFLOW 🚀\n");
    return 0;
}

---

4) Loading QNX Build Environment (Host)

Before building from terminal:

C:\Users\xx\qnx800\env_full.bat

This sets:

• QNX toolchain in PATH
• Cross compiler (qcc)
• Debug tools

env_full.bat

@echo off
REM ===== Windows system paths first (so where, dir, etc work) =====
set PATH=C:\Windows\System32;C:\Windows;%PATH%
REM ===== QNX Base =====
set QNX_BASE=C:\Users\xx\qnx800
set QNX_HOST=%QNX_BASE%\host\win64\x86_64
set QNX_TARGET=%QNX_BASE%\target\qnx
set QNX_CONFIGURATION=C:\Users\xx\.qnx
set QNX_CONFIGURATION_EXCLUSIVE=%QNX_CONFIGURATION%
REM ===== Compiler include paths =====
set MAKEFLAGS=-I%QNX_TARGET%\usr\include
REM ===== Add QNX tools to PATH =====
set PATH=%QNX_HOST%\usr\bin;%QNX_BASE%\jre\bin;%QNX_BASE%\host\common\bin;%PATH%
REM ===== Temp dir =====
set TMPDIR=%TEMP%
echo.
echo QNX SDP 8 Environment Loaded
echo.

5) Building the Project from Terminal

Navigate to project:

cd C:\Users\xx\ide-8.0-workspace\Demo

Clean (optional):

make clean

Build:

make

Output binary:

build\x86_64-debug\Demo

---

6) Connecting to VM via SSH

Because of crypto compatibility between Windows and QNX, we used:

ssh -o MACs=hmac-sha2-256 -o Ciphers=aes128-ctr root@xxx.xxx.xx.xxx
Password:
root

---

7) Running the Program on VM

Inside SSH session:

chmod +x /tmp/Demo
/tmp/Demo

OR directly from Windows:

ssh -o MACs=hmac-sha2-256 -o Ciphers=aes128-ctr root@xxx.xxx.xx.xxx /tmp/Demo

---

Full Terminal Automation Script

run.bat

call C:\Users\xx\qnx800\env_full.bat
cd C:\Users\xx\ide-8.0-workspace\Demo
make
scp -o MACs=hmac-sha2-256 -o Ciphers=aes128-ctr build\x86_64-debug\Demo root@xxx.xxx.xx.xxx:/tmp/
ssh -o MACs=hmac-sha2-256 -o Ciphers=aes128-ctr root@xxx.xxx.xx.xxx /tmp/Demo

Run:

run
