Environment variables

QNX Neutrino uses these environment variables to locate files on the host computer:

QNX_HOST The location of host-specific files.
QNX_TARGET The location of target backends on the host machine.
QNX_CONFIGURATION The location of the qconfig configuration files.
MAKEFLAGS The location of included *.mk files.
TMPDIR 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, which is the input to the compiler proper.

The qconfig utility sets these variables according to the version of the QNX Momentics IDE that you specified.
