安裝的步驟如下：

（1）git clone git://github.com/xianyi/OpenBLAS

（2）cd OpenBLAS

（3）sudo make FC=gfortran （如果沒有安裝gfortran,執行sudo apt-get install gfortran）

  (4) sudo make install (將OpenBLAS安裝到/opt下)

結果如下：

make -j 8 -f Makefile.install install
make[1]: Entering directory '/home/lbg/下載/OpenBLAS'
Generating openblas_config.h in /opt/OpenBLAS/include
Generating f77blas.h in /opt/OpenBLAS/include
Generating cblas.h in /opt/OpenBLAS/include

Install OK!
make[1]: Leaving directory '/home/lbg/下載/OpenBLAS'

編譯好的資料夾大小40M

（5）執行以下命令完成安裝

   ln -s /opt/OpenBLAS/lib/libopenblas.so  /usr/lib/libblas.so.3

   ln -s /opt/OpenBLAS/lib/liblapack.so.3 /usr/lib/liblapack.so.3
   再次執行程式，則不會發生此類錯誤

make時報錯：

/usr/bin/ld: cannot find -lgfortran
 Check what version of gcc, g++, and gfortran you have:

g++--version
gcc --version
gfortran 
 
--version

結果gfortran也有，在目錄/usr/lib/x86_64-linux-gnu/裡面，

sudo ln -s /usr/lib/x86_64-linux-gnu/libgfortran.so.3 /usr/lib/libgfortran.so

就可以了

使用編譯例子：

gcc testOpenBlas.c  -I /opt/OpenBLAS/include/-L/opt/OpenBLAS/lib -lopenblas
