check out codes from git://github.com/xianyi/OpenBLAS.git
1)Normal compile
Please read GotoBLAS_02QuickInstall.txt or type "make"

2)Cross compile
Please set CC and FC with the cross toolchains. Then, set HOSTCC with your host C compiler. At last, set TARGET explicitly.

examples:
On X86 box, compile this library for loongson3a CPU.
make BINARY=64 CC=mips64el-unknown-linux-gnu-gcc FC=mips64el-unknown-linux-gnu-gfortran HOSTCC=gcc TARGET=LOONGSON3A

3.Support CPU & OS
Please read GotoBLAS_01Readme.txt

4.Usages
Link with libopenblas.a or -lopenblas for shared library.

Set the number of threads. for example,

 or 
export OMP_NUM_THREADS=4
