1. レポジトリのクローン
$ git clone https://github.com/jluttine/suitesparse.git
2. openblasのinstall
$ brew install openblas
3. SuiteSparse_config/SuiteSparse_config.mkを編集
3-a. Mac用の設定
l372-376:アンコメント
F77 = gfortran CF = $(CFLAGS) -O3 -fno-common -fexceptions -DNTIMER BLAS = -framework Accelerate LAPACK = -framework Accelerate LIB = -lm
3-b. CFLAGSにopenblasへのパスを追加
l64:
CFLAGS = -L/usr/local/opt/openblas/lib -I/usr/local/opt/openblas/include
4. デモのビルド
$ cd CHOLMOD/Demo $ make
