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 Tool Suite that you specified.
