Query and display QNX installations and configurations
qconfig [-abc] [-d path] [-e | -i | -l] [-h] [-n installation_name] [-p] [-r program]
- Display all installed products and updates in a machine-readable format.
- Display the installed product baseline.
- Print the runtime environment strings in csh style.
- -d path
- The name of the directory where all of the individual configuration files are located. There's one configuration file per installation.
- Set up the runtime environment (see the examples).
If you specify this option, qconfig produces the commands
to set these environment variables:
You'll find this option useful when setting up the environment for building software.
- List all installations in an easy-to-parse form. The form is:
count: number_of_installations name: ... version: ... host: ... target: ...
There's a set of lines for each version of software that you've installed.
- List all installations in human-readable format (the default).
- -n installation_name
- Select a specific installation by name. The name may be incorporated as part of the configuration file using the <name> tag or, if not present, it defaults to the filename.
- Display the installed product updates.
- -r program
- Run the given program in the environment.
The qconfig utility sets or queries the QNX configuration files. It supports the coexistence of multiple versions of Neutrino on one machine.
Whenever you install a version of Neutrino, a configuration file is stored in a directory that depends on the host OS. Each configuration file defines the name of the installation and its base, host, and target directories.
The QNX_CONFIGURATION environment variable usually identifies the directory where the configuration files are stored, but you can override it by specifying the -d option. If neither of these produces a valid location, qconfig looks in /etc/qnx/qconfig before giving up and returning an error.
If you don't specify an installation with the -n option, qconfig uses the most current installation.
You can use qconfig to query your current configuration in a human-readable format, or you can use the -e option to set up your environment to use a certain installation.
List all the QNX installations:
Set up your shell environment for a specific installation:
eval `qconfig -n "QNX Momentics 6.3.0" -e`
Run a specific instance of qde (the IDE):
qconfig -n "QNX Momentics 6.3.0" -r qde
- The name of the directory that stores the configuration files.
