QNX Neutrino RTOS

• Prerequisites
• Configure build environment
• Build Kaa application
  • Exporting application

The guide explains how to cross-compile Kaa C SDK for QNX Neutrino RTOS 6.6 and create Kaa applications.

NOTE: This guide is verified against:

• Target OS: QNX Neutrino RTOS 6.6.

Prerequisites

Prior to building Kaa C SDK, install QNX Software Development Platform (SDP). To do this:

1. Register as a developer and download the following components:
   • QNX Software Development Platform 6.6
   • QNX Software Development Platform 6.6 Applypatch Patch [Patch ID 4024]
   • QNX Software Development Platform 6.6 Header Files Patch [Patch ID 3851]

2. Install SDP.

   NOTE: It is recommended that you install SDP in the default directory (/opt/qnx660 for Linux platforms).

3. Install Applypatch and Header Files Patch.

Configure build environment

To configure your build environment:

1. Install build dependencies.

   sudo apt-get install cmake build-essential
   

2. Set the path to the root directory of SDP.

   export QNX_SDK_HOME="<path_to_qnx_sdk_home>"
   

   Default value: /opt/qnx660

3. Set the target architecture.

   export QNX_TARGET_ARCH=<architecture>
   

   Supported architectures:

   • gcc_ntoarmv7le_cpp-ne
   • gcc_ntox86_cpp-ne
   • gcc_ntox86_gpp
   • gcc_ntoarmv7le
   • gcc_ntox86
   • gcc_ntoarmv7le_cpp
   • gcc_ntoarmv7le_gpp
   • gcc_ntox86_cpp

   Default value: gcc_ntox86

4. Set paths to host and target SDP files.

   export QNX_HOST="$QNX_SDK_HOME/host/linux/x86"
   export QNX_TARGET="$QNX_SDK_HOME/target/qnx6"
   export PATH="$QNX_HOST/usr/bin:$PATH"
   

Build Kaa application

Since QNX is a POSIX-compliant system, you can use the Linux guide to build and run your application.

NOTE: During CMake configuration and building step, make sure to use proper CMake toolchain.

Kaa C SDK provides the toolchain file for QNX as shown below.

mkdir -p build
cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchains/qnx.cmake -DBUILD_TESTING=OFF ..
make

Exporting application

If you have SSH enabled, you can use it on a QNX-running device to transfer your application.

scp <app_name> <user>@<ip_of_target_machine>:<app_name>
