查看lapack版本：

![2019040815261429.png][]

**lapack-devel-3.2.1-5.el6.x86\_64**

![20190408152721801.png][]

在网上查了下**\_ztpqrt2.c**

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3UwMTIzNzczMzM_size_16_color_FFFFFF_t_70 1][]

去官网：[http://www.netlib.org/lapack/][http_www.netlib.org_lapack]

上面看了一下版本信息

![20190408153242867.png][]

没有对应的库，于是这里卸载低版本lapack，安装高版本3.8

# yum remove lapack-devel

删除对应的blas-devel包

安装lapack3.8

参考：[https://blog.csdn.net/baiyang3/article/details/52790793][https_blog.csdn.net_baiyang3_article_details_52790793]

解压

# tar -xxvf lapack-3.8.0.tar.gz

复制一份make.inc

cp make.inc.example make.inc

进入BLASE

# cd lapack-3.8.0/BLAS/

# gfortran -c -O3 SRC/*.f

# ar rv libblas.a *.o

# cp libblas.a /usr/lib64/

# cp ../BLAS/libblas.a testing/

编译cblas

# cd ../CBLAS/

# make
