General Usage

OpenBLAS is an open source implementation of the BLAS (Basic Linear Algebra Subprograms) API with many hand-crafted optimizations for specific processor types. It also provides an optimized LAPACK API.

The following environmental variables have been defined:

  • $OPENBLAS_ROOT has been set to the root of the openblas installation
  • $OPENBLAS_LIBDIR points to the directory containing the libraries
  • $OPENBLAS_INCDIR points to the directory containing the header files

You will probably wish to use these by adding the following flags to your compilation command (e.g. to CFLAGS in your Makefile):

  • -I$OPENBLAS_INCDIR

and the following flags to your link command (e.g. LDFLAGS in your Makefile):

  • -L$OPENBLAS_LIBDIR -Wl,-rpath,$OPENBLAS_LIBDIR

All libraries are built with the standard 32 bit integer API
