Usage

Legacy usage

Set-up

The legacy system version does not need to be loaded.   Keep in mind that it dates to many years ago.  In general, it should be used with other tools from the same era, e.g., the system compiler version, which can be selected for your environment via module load gnu/4.8.5

Usage on Pitzer

Set-up on Pitzer

To load the default version of the OpenCV module which initalizes your environment for non legacy OpenCV, use module load opencv. To select a particular OpenCV version, use module load opencv/version. For example, use module load opencv/4.5.4 to load OpenCV 4.5.4.

In general users should employ the helper variables defined by an OpenCV module, e.g., module load gnu/9.1.0 cuda/11.2.2 opencv/4.5.4; g++ $OPENCV_INCLUDE $OPENCV_LIB bla bla.  A complete  example is available; for its location and other installation details see the output of module spider opencv/4.5.4.
