Migration considerations
3. From the drop-down list on the IDE title bar (QNX Software Developement Platform
6.6), select Use Environment Variables.
4. Restart the IDE so that the changes made to the environment variables in Step 1
are recognized by the IDE.
When the IDE restarts, it always uses your current qconfig setting as the
default version of the operating system (run-qde sets up the development
environment before starting the IDE).
You can have QNX SDP 6.6.0 installed on the same machine as QNX Momentics
6.5.0, 6.4.1, 6.4.0, 6.3.x and 6.2.x; however, the IDE installed with version 6.5.0
doesn't necessarily work with the tool chains from these earlier releases.
Starting the IDE
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. If you want to override the IDE's choice, you can choose the
appropriate build target.
Before starting the IDE to set up the current development environment:
• On a Linux host, use qconfig.
• On a Windows host, use run-qde.
Environment variables
The configuration program sets the environment variables (listed below) according to
the version of the QNX Momentics tool suite that you specify. The host uses these
environment variables to locate files on the host computer:
Environment variable
Description
QNX_CONFIGURATION
The location of the qconfig
configuration files.
QNX_HOST
The location of host-specific files.
QNX_JAVAHOME
A directory used for temporary files. The
gcc compiler uses temporary files for the
output of one stage of compilation used
as input to the next stage. For example,
the output of the preprocessor is the input
to the compiler.
