BLAS++ Example
================================================================================
This is designed as a minimal, standalone example to demonstrate
how to include and link with BLAS++. This assumes that BLAS++ has
been compiled and installed. There are two options:
## Option 1: Makefile
The Makefile must know the compiler used to compile BLAS++,
CXXFLAGS, and LIBS. Set CXX to the compiler, either in your environment
or in the Makefile. For the flags, there are two more options:
a. Using pkg-config to get CXXFLAGS and LIBS for BLAS++ (recommended).
pkg-config must be able to locate the blaspp package. If it is installed
outside the default search path (see `pkg-config --variable pc_path pkg-config`),
it should be added to `$PKG_CONFIG_PATH`. For instance, if it is installed
in /opt/slate:
export PKG_CONFIG_PATH=/opt/slate/lib/pkgconfig # for sh
setenv PKG_CONFIG_PATH /opt/slate/lib/pkgconfig # for csh
b. Hard-code CXXFLAGS and LIBS for BLAS++ in the Makefile.
Then, to build and run `example_gemm` and `example_util` using the
Makefile, run:
make
make test
## Option 2: CMake
CMake must know the compiler used to compile BLAS++. Set CXX to the
compiler, in your environment.
Create a build directory:
mkdir build && cd build
If BLAS++ is installed outside the default search path, tell cmake
where, for example, in /opt/slate:
cmake -DCMAKE_PREFIX_PATH=/opt/slate ..
Otherwise, simply run:
cmake ..
Then, to build and run `example_gemm` and `example_util` using the
resulting Makefile, run:
make
make test
