ubuntu 18.04中编译安装使用 lapack 示例
作者:互联网
0.0 拉取 ubuntu:18.04 docker image:
sudo docker pull ubuntu:18.04
0.1 启动docker:
sudo docker run --name Lapack_running -it \
-v /dev:/dev -v /usr/src/:/usr/src -v /lib/modules/:/lib/modules --privileged --cap-add=ALL ubuntu:18.04
以下是docker内操作:
0.2 mv /etc/apt/sources.list /etc/apt/sources.list.backupLL
0.3 echo "deb http://mirrors.163.com/ubuntu/ bionic main restricted universe multiverse" > /etc/apt/sources.list
0.4 apt-get update && apt-get upgrade
0.5 apt-get install vim
0.6 将下面的ubuntu18.04 163 源全部加入到 /etc/apt/sources.list 中: vim /etc/apt/sources.list
0.7 apt-get update && apt-get upgrade
0.8 安装必要软件:
apt-get install python3 gfortran wget make
0.8 mkdir 并且 cd 至源码目录
0.9 下载lapack包:
wget https://github.com/Reference-LAPACK/lapack/archive/refs/tags/v3.10.0.tar.gz
0.10 解压:
tar -zxvf v3.10.0.tar.gz
0.11 cd lapack-3.10.0
0.12 cp make.inc.example make.inc
0.13 vim Makefile 并且将12和13行修改为如下:
#lib: lapacklib tmglib
lib: blaslib variants lapacklib tmglib
0.14 开始编译:
make -j32
0.15 cd LAPACKE #cd 进入LAPACKE文件夹,这里是lapack的C语言接口源码
0.16 编译LAPACKE:
sudo make -j32 # 编译lapacke
0.17 手动安装lapacke:
cp include/*.h /usr/local/include #将lapacke的头文件复制到系统头文件目录
0.18 手动安装lapack:
cd .. #返回上级目录 lapack-3.10.0/
cp *.a /usr/local/lib # 将生成的所有库文件复制到系统库目录
0.19 使用示例:
在系统中任意文件夹中,将如下代码存储为helloLapack.c
//helloLapack.c
#include <stdio.h>
#include <lapacke.h>
int main (int argc, const char * argv[])
{
double a[5*3] = {1,2,3,4,5,1,3,5,2,4,1,4,2,5,3};
double b[5*2] = {-10,12,14,16,18,-3,14,12,16,16};
lapack_int info,m,n,lda,ldb,nrhs;
int i,j;
m = 5;
n = 3;
nrhs = 2;
lda = 5;
ldb = 5;
info = LAPACKE_dgels(LAPACK_COL_MAJOR,'N',m,n,nrhs,a,lda,b,ldb);
for(i=0;i<n;i++)
{
for(j=0;j<nrhs;j++)
{
printf("%lf ",b[i+ldb*j]);
}
printf("\n");
}
return(info);
}
0.20 使用gfortran进行编译:
gfortran helloLapack.c -llapacke -llapack -lrefblas -o helloLapack
0.21 执行示例:
./helloLapack
打印结果为:
2.000000 1.000000
1.000000 1.000000
1.000000 2.000000
