Has anyone gotten lapack to work on centos 7?
If so, how?
Most recently, I installed lapace-devel and let yum bring in what it wanted.
Whenever I try to link, I get a long list of undefined references ending with
/usr/lib/gcc/x86_64-redhat-linux/4.8.5/../../../../lib64/liblapacke.so:
undefined reference to `dgeevx_'
[hennebry at localhost test]$ nm -D /usr/lib64/libblas.so | grep dge
0000000000018850 T dgemm_
0000000000011080 T dgemv_
00000000000170c0 T dger_
[hennebry at localhost test]$
confirmes that the reference is not there.
Installing blas or atlas first does not help.
When installing lapack-devel, yum always wants to install blas-devel.
What do I need?
