Building Options

The HotSpot Makefile supports several build options that you specify when running make. To use one or more of the build options, instead of simply running make, you run:

make <option1>=<value> <option2>=<value> ... <optionN>=<value>.

Here are the build options currently supported:

  • SUPERLU=0 or SUPERLU=1 : This controls whether or not HotSpot links to the SuperLU library and takes advantage of it to improve simulation times. The default value is 0.
  • DEBUG=0, DEBUG=1, or DEBUG=2 : Specifying a higher level of DEBUG compiles HotSpot with more flags to support debugging, such as -ggdb and -Wall. This does not change HotSpot's runtime behavior. The default value is 0.
  • VERBOSE=0, VERBOSE=1, VERBOSE=2 : Specifying a higher number for VERBOSE causes HotSpot to print more information at runtime. The default value is 0, which should be fine for most users.
