Using older toolchains with the IDE

You can upgrade the IDE and continue to use an older toolchain if required. For example, you can have a QNX Software Development Platform version 6.5.0 installed on the same machine as QNX Momentics 6.4.1, 6.3.x and 6.2.x, and in most cases, the IDE installed with version 6.5.0 should work with the toolchains from these earlier releases.

To upgrade the IDE and use an older toolchain, do the following:

To change versions of the QNX Momentics Tool Suite for the IDE, use QWinCfg for Windows, or use qconfig for other hosts, to set the version of the QNX Momentics Tool Suite for the IDE you want to use.
Start the IDE.
Select Window > Preferences , and then select QNX.
Select Use Environment Variables from the Select Install list on the Global QNX Preferences page.
Click OK for the changes to take effect.
Restart the IDE so that the changes made to the environment variables in Step 1 are recognized by the IDE.
Note: When the IDE restarts, it always uses your current qconfig or QWinCfg setting as the default version of the operating system.

Once you specify the Use Environment Variables option, when you start the IDE, it uses your current qconfig choice as the default version of the OS; if you haven't chosen a version, the IDE chooses an entry from the directory identified by QNX_CONFIGURATION (the location of the qconfig configuration files.) If you want to override the IDE's choice, you can choose the appropriate build target.
