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.
