Set up your environment for QNX

Set up your environment to develop for QNX.

Set up your environment to develop with QNX.
To create a Unity application for QNX, you first need to set up your Unity project to support QNX. To support QNX, a Unity project requires certain environment variables and dependencies.
Note
You must install the QNX platform package before you can set up your environment. For more information, refer to Install the platform package for QNX.

Set the environment variables

After you have installed the Unity Editor, you will need to set the environment variables. Open a terminal window and run one of the following commands to set the environment variables in the local shell and start the Editor from there.
  • qnxsdp-env.bat
    (Windows)
  • source path/qnxsdp-env.sh
    (Linux and macOS)
Alternatively, you can set the environment variables 
QNX_TARGET
and 
QNX_HOST
either locally in a terminal or globally, and then run the Editor.
These are the environment variables you need to set:
  • QNX_TARGET=/path/to/target/qnx
  • QNX_HOST=/path/to/host/platform/arch
  • Add to 
    PATH:
    $QNX_HOST/usr/bin
    (for QNX 7.1 only)

Dependencies

QNX must provide direct and indirect dependencies so Unity can run correctly.

Direct dependencies

Direct dependencies load at the application startup. Use the following dependencies for all versions of QNX:
  • libm.so.3
  • libgcc_s.so.1
  • libscreen.so.1
Then, add dependencies specific to your version of QNX:

QNX version

Supported dependencies

QNX 7.1
  • libc.so.5
  • libsocket.so.3
    (also known as 
    io-pkt
    )
  • libasound.so.3
QNX 8.0
  • libc.so.6
  • libsocket.so.4
    (also known as 
    io-sock
    )
Note
QNX 8.0 has no sound support so doesn't need the 
libasound
dependency.

Indirect dependencies

Indirect dependencies load when needed during the application runtime, as a shared library.

Type

Dependencies

Webcam
libcamapi.so
(for QNX 7.1 only; QNX 8.0 has no camera support.)
OpenGL ES
libEGL.so.1
, 
libGLESv2.so.1
Devices
libudev.so.1

Troubleshooting

If you notice one of the following issues in the Build Profiles window, then the QNX SDP Environment isn't set up correctly:
  • Unable to find QNX_TARGET in Environment.
  • The build environment does not fit the selected QNX Version.
  • The build environment does not contain the selected QNX Architecture.
Before starting the Editor, always check that you have the QNX SDP Environment set up correctly for the Editor to register it. For more information, refer to QNX Software Center.
